Developed by NetEnt, and with an incredible return to player (RTP) rate of 98.9%, Mega Joker is comfortably one of the best payout slot games for UK players. The 98.9% RTP rate is well above the industry average, and it's a video slot with low variance. Payout rates are frequent, but the prizes tend to be small when they land. Mega Joker has a 3x3 playing grid, five paylines, and a maximum win of £30,000. Mega Joker slot review.

RTP rates on Barcrest’s Rainbow Riches Reels of Gold vary according to how bold players are in their wagers. Any bet under £2 is considered conservative by this video slot, generating an RTP of 92%; wagers higher than this mark steadily raise the RTP to 96%, while the bravest wagers will push the RTP up to 98%. With a jackpot of 500x the stake and 100 different paylines in play, this leprechaun-themed classic is a favourite of many online casino players. Rainbow Riches Reels Of Gold slot review.

NetEnt’s Steam Tower comes with five reels, 15 paylines, and an RTP of 97.04%, making it one of the best paying slot games in the UK. Bet limits range from £0.15 to £150, with the biggest jackpot win paying out at 2,000x the stake. During the free spins bonus round – triggered by stacking Wild icons – all bet lines are subject to the in-play multiplier, which updates prior to each free spin and according to the level players are on.

In recent years, Microgaming’s Immortal Romance has been one of the best slots for winning. There are 243 different ways to win on this 5x3 video slot, producing an RTP rate of 96.8%. Wagers range from 30p to £30, with a jackpot payout of 12,150x the stake. Immortal Romance is a high variance slot – big wins are extremely hard to come by, and players should expect frequent but smaller payouts instead. In fact, Immortal Romance’s hit frequency of 31.21% means that on average, players will find a winning combination almost every three spins.

Playtech’s Ugga Bugga is a 2013 slot with a massive RTP rating of 99.07%. Although this RTP is way above the average, Ugga Bugga is a low volatility slot, meaning that payouts are frequent but small. This slot game has a unique layout, with icons appearing on a 10x3 grid, generating a maximum payout of 1,000x the stake. With a wager range of £0.10 to £250, this means players can stand to win a max jackpot of £250,000.

2015’s Ooh Aah Dracula by Barcrest is a ten payline, medium volatility slot that takes place on a 5x3 grid. Players wager coins rather than cash in this game, with betting ranges stretching from 0.01 to 50, and a max win of 250,000 coins. The game incorporates two RTP rates: for the base game this stands at 96%, but if players sink their fangs into the High Roller bonus, the RTP is bumped all the way up to an impressive 99%.

Released in 2014, this is a high volatility slot with five paylines and a base RTP rate of 95%. Betting limits are strict, with a maximum bet of £2 and a maximum payout of 6,000 coins.

The Catfather aligns Garfield with Don Corleone in this unusual slot by Pragmatic Play. The game was released in 2016 to much acclaim, with players enjoying the quirky theme and high RTP rate of 98.1%. The Catfather is a low volatility slot with nine paylines that takes place on a 5x3 grid, where all kinds of felines look to build winning combinations. Pragmatic even had fun with the betting limits, which begin at £0.09 and rise to £45; max payouts are set at 5,000x the stake. The Catfather slot review.

This high volatility slot from Yggdrasil is known for being one of the best payout slots available. Jokerizer features an RTP range of 88-98%, a £60,000 maximum win, and 10 paylines across its 5x3 reel structure. Hitting a win sends players to the Jokerizer mode, with the chance to land a mystery win. If you secure two joker symbols during this round, the mystery prize will drop with a potential 6,000-coin payout. Bets range from 10p to £2. Jokerizer slot review.

What Do We Class as a High Payout Slot?

We define a high payout slot as one with a return-to-player (RTP) percentage above 96%. In its simplest terms, this figure means players can generally expect to receive £96 back from every £100 wagered on one specific game. 96% is the average payout rate in the realm of online slots, so we classify anything above the median as being favourable to players.

It’s important that our readers don’t overstate this favourability here. When a slot is in the testing phase, RTP percentages are calculated over millions of simulated spins, which makes it likely for individual playing sessions to deviate from this mark, sometimes significantly. After all, if players knew exactly what they’d win and lose from a slot, there wouldn’t be much point in spinning the reels.

There are thousands of slots with RTP rates higher than 96%, so to find the very best payout slots, we whittle down the list according to criteria such as themes, bonus rounds, jackpot prizes, game developers, and minimum/maximum bets. What remains is a collection of the best paying slot games.

The design of the VoodooDreams casino homepage makes seeing what’s available a hassle-free experience. I found the registration process simple, and I got my 100% up to £50 bonus and 50 free spins on Book of Dead as soon as I made my qualifying deposit. There are more than enough slots here to keep even diehard slots enthusiasts happy, and I feel that most will also find the site’s unique loyalty scheme loads of fun. The program is magical-themed and involves casting spells to collect free spins and cash rewards! Instant payouts to most banking options round off the perks at VoodooDreams, leaving the only concerns the wagering requirements attached to the sign-up offer and the absence of a mobile app.

From our list of the top ten high payout slot machines on this page, VoodooDreams boasts seven of them: Mega Joker, Rainbow Riches Reels of Gold, Steam Tower, Immortal Romance, Jackpot 6000, Blood Suckers and Jokerizer.

Setting out to discover if All British Casino was a good pick for UK players, I was pretty impressed by what I found. Signing up was simple, and I was able to claim the 100% up to £100 matched deposit bonus and dive into the slots collection in just a few minutes. I was wowed by the range of software providers that contribute to the library. This included the likes of NetEnt, Thunderkick and Nolimit City, so I feel confident in thinking that most players will be as pleased as I was by the choice of games. The mobile app, tested on iOS, also hit the spot, offering a smooth playing experience and access to plenty of best payout slots.

All British Casino hosts half of the games in our list of the highest paying slots: Mega Joker, Steam Tower, Immortal Romance, Ooh Ahh Dracula and Jackpot 6000. The original Blood Suckers slot isn’t in the catalogue, but you can play Blood Suckers II (96.94% RTP) and Blood Suckers Megaways (97.66% RTP), which offers players increased payline routes to success.

Taking Hyper Casino for a spin proved an enjoyable experience. The sign-up process at this online casino was simple, and I was able to claim a 100% boost to my first deposit up to £100. The bonus cash on offer is a welcome treat, even though I’d prefer to see the above average 45x wagering requirement come down a bit. Despite the high playthrough demand, I had fun exploring the site, finding it well organised and nicely designed with fun space-themed graphics. The slots are sorted into different collections, making it easy to find the games you want, and I also appreciated being able to filter slots by different developers, such as Play’n GO and Elk Studios.

Among the best playing slot games in our top ten list at Hyper Casino are Mega Joker, Steam Tower, Immortal Romance and Jackpot 6000. Like All British Casino, the first Blood Suckers release isn’t available, but Blood Suckers II and Blood Suckers Megaways both make the cut.

Duelz Casino made a good impression from the start. I found the design of the site appealing and quickly noticed several perks that would appeal to players. The welcome offer of a 100% up to £100 bonus and 100 free spins on Book of Dead is definitely one of the plus points, even if the T&Cs are a little strict. Exploring the site revealed a great variety of slots to choose from, including top titles like Gonzo’s Quest and Finn and the Swirly Spin. All the game tiles are transparent, which is something rarely seen and looks really good — in my opinion anyway! The promos also deserve a mention, with head-to-head tournaments with cash prizes starting every 15 minutes and 10% cashback every Friday.

Duelz hosts four games from our list of the best payout online slots: Mega Joker, Steam Tower, Immortal Romance and Blood Suckers. Blood Suckers Megaways is also available for more dynamic winning combinations.

LuckLand welcomes new customers with a 100% up to £50 matched deposit bonus and 50 free spins on Starburst — a sign-up offer that proved easy to claim and fun to use. The only small concern was that the wagering requirements are quite high at 40x. Nonetheless, the site boasts an excellent selection of games, and the library was relatively simple to explore, despite the lack of any significant filtering options. I was able to fire up new top payout slots like Trojan Kingdom and Gold Blitz directly from the homepage and use the search function to find old favourites. The promos page is also noteworthy, with slots offers for Pragmatic Play and Spinomenal, as well as a reload deal worth up to £200 in bonus cash every week.

Steam Tower and Immortal Romance are the only two high payout slots from our top ten list to currently feature at LuckLand. LuckLand might not rank as a casino with the highest slot payouts, but there are still loads of titles to enjoy in the collection.

A new sister site to the popular Buzz Bingo site, Buzz Casino certainly has what it takes to become a success in its own right. This new online casino comes loaded with plenty of slots, and welcomes newcomers on board with 200 free spins on Fishin’ Frenzy The Big Catch. These free spins were credited automatically as soon as I had wagered my first deposit of £10 on slots and came with a £400 wagering requirement. I also received a £5 slots voucher for my local Buzz Bingo club. Checking out the promos for returning players revealed a handful of different offers, including a monthly £200,000 slots prize draw and the chance to win guaranteed bonus spins on the Sizzling Slots Spinner, so there’s plenty of fun to be had.

Immortal Romance is the only one of our best payout slots to feature at Buzz Bingo, but Blood Suckers Megaways does give players a taste of the vampiric as they look for a healthy return.

Signing up for Casino Casino was really simple, and I was all set to explore the site — and enjoy a 100% up to £100 matched deposit bonus — in minutes. There’s no max cash-out for this bonus, though it does come with an above average 40x playthrough demand. I found no shortage of top slots to enjoy at Casino Casino, and the site’s design makes it really easy to pick out best payout slots. The games page, for example, is organised into collections such as tournament games and new games, and it’s also possible to sort games by developer, such as Novomatic and Microgaming. I found both features handy while finding my way around. Fast processing of withdrawal requests adds to the appeal of this site.

Popular online and on the high street, I was expecting to be impressed by Grosvenor Casino, and I wasn’t disappointed. After signing up and claiming a £30 bonus by depositing £20, I set out to explore the site. There ended up being several areas where Grosvenor excels, including in its selection of slot games. These are arranged into collections such as the newest releases and frequent wins, making it easy to find games I was interested in. Along with offering plenty of best payout slots, Grosvenor Casino also offers lightning-fast payouts, with many processed within just 15 minutes. With that in mind, about the only niggle I can report here is that the promos page is skewed towards sports betting offers.

Four of our best payout slots feature at Grosvenor: Mega Joker, Rainbow Riches Reels of Gold, Steam Tower and Immortal Romance. For your Blood Suckers fix, you can play Big Time Gaming’s Megaways version.

My first impression of the Spin Rio online casino was how bright and colourful the site was, and I feel that the fun carnival theme will appeal to lots of players. Signing up was really simple, and I found the welcome package of 100 free spins and up to £200 bonus across my first three deposits generous, even if it did come with a 35x rollover demand and a £500 win limit. The slots library at Spin Rio is well organised, and it’s really easy to jump into top payout slots like Big Bass Bonanza and Immortal Romance direct from the homepage. If there’s a downside to report here, it’s that the promotions page could be better populated, though the site does offer Pragmatic Play Drops & Wins tournaments.

From our list of the ten best paying slot games, only Steam Tower and Immortal Romance are accounted for at Spin Rio. But that doesn’t mean this carnivalesque site isn’t a high payout casino – browse the games library to find an RTP percentage you like.

Best Payout Slots Explained

Looking for the best payout slots? You’re in the right place. On this page, we’ve got everything you need to know in order to find slots that meet this description — but what exactly qualifies as the ‘best’? 

Slot payouts can be measured in a number of different ways. Many players will be looking for the highest RTP or ‘return to player’ — the percentage of stakes a slot pays back out as winnings. Others will be seeking slots with a certain size or frequency of payout, which is known as volatility. And some players are simply looking for the biggest potential win, often found in games with progressive jackpots. Keep reading and we’ll dive into each of these slot payout factors in more detail.

Return to Player

The Return to Player or RTP of a slot is a characteristic that describes the percentage of money paid in that’s paid back out as winnings. Take a slot with 95% RTP, for example. For every £100 bet on the slot by players, £95 is returned as winnings. So — broadly speaking — the higher the RTP, the ‘better’ the payouts. 

A related concept is house edge, which is essentially the inverse of RTP. A game with 99% RTP could be described as having a house edge of 1%. 

It’s important to keep in mind that RTP numbers are mostly theoretical. They’re calculated by slots developers over millions and millions of spins, so you’ll never see them bear out during your own play session. Nonetheless, it’s a good idea to pick a slot with higher RTP if you’re seeking the best payouts. 

How to Find a Slot’s RTP

Usually, developers are required to publish RTP numbers for their slots. You can often find this information in the help section of the slot or on the developer’s own website. Sometimes there are two figures — the ‘expected’ RTP is theoretical, while the ‘actual’ RTP is based on the slot’s historic payout performance.

While RTP gives us an idea of how much a slot pays out over time, it’s only one part of the picture. Volatility — or variance — is the second payout characteristic to consider, and describes the size and frequency of payouts.

  • Low volatility slots tend to pay out more frequently but in smaller amounts. 
  • Medium volatility slots offer a mix of big and small wins at varying frequencies.
  • High volatility slots may pay out less frequently, but often in larger amounts.

The slot variance you prefer depends entirely on your own playstyle. It can also be helpful to consider your budget — those with less to play with may prefer to rack up some smaller wins before burning through their bankroll, while larger budgets can allow you to weather the long dry streaks more common in high variance slots.

How to Work Out a Slot’s Variance

Some developers will include the volatility in the help files of the slot, but this isn’t always the case. Thankfully, it’s fairly easy to work out for yourself — just take a look at the paytable. Seeing lots of low-paying symbols and just a few high-paying ones? It’s likely the slot has low volatility. The reverse also holds true, with high volatility slots tending to have more high-paying than low-paying symbols. 

The third characteristic to consider is the maximum payout. Quite simply, this is the largest amount you can win on the slot. You can think about max payout in a few ways:

  • Maximum base game payout is the max stake multiplier per payline. For example, Starburst’s maximum base game payout is 250x your bet, which requires landing five of the Bar symbols on a payline. 
  • Maximum bonus round payout is a separate maximum that applies during bonus rounds. Book of Dead has a max payout of 5,000x your stake in the bonus round, for example.
  • Maximum overall payout is a fixed ceiling on what you can win, although it’s not found in every slot. If you exceed this amount, the round ends and the payout is added to your balance. 
  • Jackpots are separate prizes that are won when the player fulfils a specific requirement. Many jackpot slots feature different tiers of prize, while some are progressive and increase with every bet. Mega Moolah, for example, has paid out jackpots worth tens of millions in the past.

How to Find the Maximum Payout of a Slot

Again, you’ll often find the max payout of a slot within the help files. If not, it’s simple enough to calculate yourself. Take a look at the paytable and find the highest-paying symbol. Multiply the payout by the maximum stake allowed in the game. 

For example, Gonzo’s Quest has a max payout of 2,500x in the base game and a max stake of £50. So theoretically you could win a maximum of £125,000 if you fill the board with the highest-paying symbol.

Together, RTP percentages, slot volatility, and maximum wins all influence the overall payout rate of an individual slot. A slot’s payout rate can therefore be described as a product of how these three factors interact with one another.

A low volatility slot with a high maximum win, for example, is one way in which developers temper the payouts of their games – in this example, it would be rare for players to hit a large win, but when it happens, it will dramatically influence the overall RTP percentage.

Before playing one of our best payout slots, take a look at these three factors, and consider how they might affect your chances of success. For those on small budgets, it’s best to play low volatility games so that wins aren’t too sparse.

How We Review Casinos with the Best Payout Slots

Each page on TopRatedCasinos has a focus, from the best payout slots to the fastest payment methods. Before we make a casino recommendation, sites must first satisfy a range of criteria pertaining the overall online gambling experience. Some elements of the review, like customer service, are always relevant, while others carry more significant weight depending on the focus of the page. For the best payout slots, here’s what we’re really interested in during our reviews.

Licensing and Security

Every time you come across a slot or casino recommendation on our site, we guarantee that it’s legal and safe to play. We’re only interested in reviewing licensed games and casinos, because the safety of our readers is paramount. 

For the best payout slots page, we naturally want to direct readers towards casinos that feature as many of these games as possible. After this, we look more generally at size of the library, contributions from the biggest game developers, and variety in terms of themes and mechanics.

Hosting a bunch of high payout slots isn’t much use if withdrawing funds from the casino is needlessly difficult. That’s where a decent range of payment methods, such as e-wallets and bank transfer systems, really helps – these banking options often facilitate payout times at a faster rate than debit cards.

We want to see frequent, high-value bonuses offered to all players, as well as a healthy welcome bonus when signing up to a new casino. For the purposes of this page, we also want to see good bonus eligibility on high payout slots.

Our team of reviewers have put many different online casinos to the test. In order for one site to stand out over another, it needs to offer a point of difference. Were there any glitches or malfunctions during the review? Was the site easy to navigate? Is there a particularly attractive or innovative reward scheme? These are the kinds of questions we ask in this section. 

Some casinos host thousands of games, running the risk of over cluttering the site and slowing it down. It’s vital that players are able to move through the casino without any hiccups, and that it’s easy for them to find what they’re looking for – such as the best payout slots.

During testing we always engage with the casino’s customer support, knowing that a timely, helpful and friendly service is one of the cornerstones of a great casino. Live chat is the best way to facilitate this, and top online casinos offer this service 24/7.

Best Payout Slots by Category

Whether you’re looking for the highest RTPs or the biggest progressive jackpots, we’ve got a great selection of slots that fit the bill — check out the range below.

High RTP Slots

If you’re looking for slot machines with the lowest house edge, give these slots with high RTP a try.

  • Goblin’s Cave – This Playtech slot offers the highest RTP on the market — an incredible 99.32% when you bet the maximum amount. This 3-reel, three payline game also has a hold feature where, after each new spin, you get to choose to hold symbols for the next round and get a better chance of landing a win. One thing to keep in mind is that the maximum bet requirement means that only those with higher bankrolls will be able to enjoy the maximum RTP.
  • Ugga Bugga – Also developed by Playtech, a 99.07% RTP makes Ugga Bugga one of the highest payout slots you can play at online casinos. This game is very similar to Goblin’s Cave and also has a hold feature, adding a tactical element you don’t usually get with slots. Line up three wild symbols and you’ll land the jackpot which pays out at 1,000 times your bet.
  • Ooh Aah Dracula – This game has a base RTP of 96% which shoots up to 99% when you play the Big Bet mode, making this Barcrest title one of the best payout online slots available. There are two high roller options: play 5 spins for 20 coins and land the Graveyard Bonus if free spins are activated, or play 5 spins for 30 coins to be in with a chance of activating the Super Graveyard Bonus feature.
  • Jackpot 6000 – Jackpot 6000 is a NetEnt slot in which the RTP can reach up to 98.9%. This game is based on classic arcade slots but, thanks to the Supermeter mode, it’s far from your standard 3-reel game. This option is activated each time you land a win when betting ten coins, offering enhanced bonus features as well as the chance to reach the maximum RTP of 98.9%.
  • Jokerizer – This Yggdrasil slot is another title that offers an increased RTP in high roller mode. This Jokerizer mode, in which the RTP increases to 98%, is activated whenever you land a win. This mode does cost 20 coins per spin, however, so you’ll need a sizeable bankroll to activate the maximum payout percentage.
  • Blood Hunters – The second vampire-themed game to make our list of the best RTP video slots is Blood Hunters from Leander Gaming. There’s plenty to keep players entertained here, including wilds and scatters that pay out thousands of times your stake, as well as the Coffins pick game. The game itself looks great too: played on five reels, the symbols include various vampiric items plus familiar characters from Bram Stoker’s classic Dracula novel. The RTP of this title is substantial too, clocking in at 97.99%.

If progressive jackpots are famous for their enormous payouts, then the titles funding them must be the best paying slots, right? Well, quite possibly, but only if you win the elusive jackpot, which is easier said than done.

A progressive jackpot can be standalone, which means it’s individual to one game or pooled between games. In these cases, wagers on multiple titles contribute to the prize fund, so top prizes tend to grow larger and faster.

Here are some of the most popular progressive jackpot slots around today:

  • Age of the Gods: God of Storms – Sitting within Playtech’s massively popular Age of the Gods series, God of Storms has four progressive jackpots. The largest seeds at £100,000.
  • Buffalo Blitz Megaways – A modern update to the original Buffalo Blitz slot, this version has up to 117,649 ways to win as well as four jackpots. The Blitz Jackpot is the largest, starting at £100,000.
  • Atlantean Treasures Mega Moolah – This underwater redesign of Mega Moolah is linked to the same progressive jackpot as the original title, which seeds at a whopping £1 million.
  • Jackpot Bells – Playtech’s classic style slot offers different progressive jackpots based on your stake size. The largest often tops £100,000.
  • Absolootly Mad: Mega Moolah – Another slot in the Mega Moolah jackpot network, this one sees players join the Mad Hatter’s tea party for a chance at the top prize.

It’s worth keeping in mind that many progressive jackpot slots have lower RTPs than other games. Microgaming’s Mega Moolah, for example, holds the title for the biggest ever online slot payout — one very lucky player bagged more than £16,000,000 on this game. You might think that this makes Mega Moolah the ‘highest paying slot’, but this title has an RTP of just 88.12%.

That’s pretty low on the RTP spectrum. If you get lucky enough to land a rare win, it’s likely to be a bigger prize. However, on average you’re far less likely to land some returns on Mega Moolah than on the best RTP slots.

Want to try your hand at a progressive jackpot slot without sacrificing a solid RTP rate? Here are some progressive jackpots with high return to player:

  • Mega Joker by NetEnt – 98.9%
  • Mega Fortune by NetEnt – 96.6%
  • Age of the Gods: Wheels of Olympus by Playtech – 96.13%
  • Rhino Blitz by Playtech – 95.96%

Developers are always releasing weird and wonderful slots to keep things fresh at online casinos. Here are some new slots with the best payouts.

  • Fruit Salad – This simple five-reel slot is inspired by classic fruit machines and boasts an RTP of 96.94%. It has low volatility and the max win is 555x your bet.
  • Lucky Fish Finder – Dive below the ocean waters and you’ll get to spin the reels of this 5×5 slot with a 96.96% RTP. Players can control the volatility by selecting how many ‘boots’ to have in play.
  • Blood Suckers Megaways – This vampiric spin-off reimagines Red Tiger’s massively popular slot in the Megaways format, with up to 117,649 ways to win and an RTP of 97.66%.
  • Chilli Willie – Join the fiesta in this Mexican-themed slot with five reels and 10–50 paylines. The RTP stands at a respectable 97.07%.

While the simplest slots might offer just five paylines, there are plenty of Megaways titles on the market with many thousands of ways to win. Here’s a selection of our favourites:

  • Monopoly Megaways – Big Time Gaming’s Megaways feature changed the slots landscape forever by boosting the number of ways to win to an incredible 117,649 and beyond. Monopoly Megaways sticks at this payline figure, and allows players to win a max jackpot of 14,700x their stake. There are six reels on the grid here, with each one featuring between two and seven symbols. If each reel appears with seven symbols, then all of the slot’s paylines are live. Mr Monopoly himself joins you round the classic board, and wins are formed by matching two or more symbols on adjacent reels. With an RTP of 96.5%, plenty of bonus features, and classic Monopoly iconography, this is definitely a slot worth playing.
  • Holy Diver Megaways – Join the medieval knights of the realm in this six-reel, 96.5% RTP slot from Big Time Gaming. There are 15,120 ways to win in the base game here, but this can rise to an enormous 586,789 when working in unison with all the bonus features. These bonus opportunities include wild upgrades, wild reels, exploding wilds, multipliers, and free spins. As you spin the reels, the knight moves through the scene encountering treasure chests, each with their own prize inside.
  • White Rabbit Megaways – Big Time Gaming’s White Rabbit Megaways has the highest RTP rating of the five slots listed here at 97.2%. Inspired by the zany creatures of Lewis Carroll’s stories, this six-reel slot offers players 248,832 different ways to win and features wilds, multipliers, free spins and an expanding symbol – this expansion can stretch up to twelve symbols on one reel. As you’d expect from a Lewis Carroll-themed gamel, the aesthetics are unconventional and slightly jarring at times, but this all adds to an excellent gameplay experience.
  • Who Wants to be a Millionaire Megaways – Based on the iconic TV quiz show, this is another product of the Big Time Gaming studio that gives players the chance to win a whopping 70,000x their stake. There are no opportunities to increase the paylines here, which is set at 117,649 throughout the game. This slot really comes to life when punters play the Hot Seat free spins feature, which mimics the formula of the TV show by offering players the option to use their lifelines and work their way up the board in an attempt to land up to 50 free spins. With an RTP rate of 96.24%, you can put your knowledge to the test with this classic slot.
  • Gonzo’s Quest Megaways – NetEnt’s first Gonzo’s Quest title is one of the abiding games of the video slot genre, revered by online casino players around the world. This Megaways adaptation is faithful to the original, taking place in the same sultry heat of the South American jungle. Only this time, the six reels and cascading avalanches give players 117,649 different ways to win. With multipliers, free spins bonuses, a random earthquake feature, and an RTP of 96%, this slot is a triumph of the iGaming world.

  • Ocean Princess – 99.1%

  • Olympus Thunder – 97%
    With Mount Olympus standing in the backdrop, spin the reels with the power of the gods in Olympus Thunder. Zeus himself will reward players with three re-spins when landing on the middle reel, during which he expands to boost combo potential. Free spins and multipliers can also be unlocked by the lightning bolt scatter.
  • Witch Pickings – 96%
    Slot providers usually deploy the witch theme to draw haggard, creepy characters, but this isn’t the case with Witch Pickings. This slot has a relaxed nature, and the witches themselves couldn’t be more amiable — they serve as the slot’s scatter, and landing three of these symbols will trigger five free spins and a picking game.
  • Ramesses Riches – 96%
    The simple design of this slot will be endearing to many players, with ancient Egyptian iconography laid over the reels. Ramesses is the game’s wild, while the Ankh will launch a gamble feature that gives players the chance to double their winnings and the opportunity to claim some free spins.
  • Starmania – 97.7%
    Trek through the jungle with Gorilla Go Wild, where Gary the lemur will aid your quest for prizes. He acts as the scatter, and will trigger the Gorilla’s Feature Kingdom bonus when three or more land on the reels. At this point, players get to decide which bonus they want to play; the longer you spin the reels, the more bonus features you’ll unlock.

Best Payout Mobile Slots

Want to play the best payout slots while on the go? All the top online casinos have mobile-friendly websites, so you can do exactly that when you play at one of our recommended slot sites.

Software developers like NetEnt, Microgaming and Playtech all optimise their games for mobile play, meaning you can enjoy smooth spinning whenever you feel like it – whether that’s on the sofa, on the commute, or while you’re waiting for that mate that’s always late.

If you want to enhance your mobile slots experience, we recommend downloading a casino gambling app whenever possible. Your online casino might not have one of these available, or you may not like the idea of downloading the software onto your device, but there are a few reasons why this is our preferred option – we’ve bullet listed the pros and cons below.

Using Casino Bonuses on the Best Payout Slots

Online casino bonuses are a great way to boost your bankroll, either through cash tokens or free spins.

When you sign up to a new online casino, the bonus on offer could be a deciding factor in where you end up spinning the reels, and there are a few factors to consider for the major bonus schemes available when you’re making your decision.

Matched Deposit 

Matched deposit bonuses see the casino equal a portion of your deposit up to a set limit. Typical offers for new customers are as high as 100%, which effectively doubles your playing funds with bonus money.

From our list of the top UK online casinos with high payout slots, seven of them currently offer matched deposit bonuses: VoodooDreams, All British Casino, Hyper Casino, Duelz, LuckLand, CasinoCasino and Spin Rio. If you’re looking to make a withdrawal from a matched deposit bonus, you’ll want to stick to slots when using bonus funds, since these have the most favourable wagering contributions.

Often lumped in alongside matched deposit bonuses are free spins, which offer players a spin of the reels for free. Alongside their matched deposit offers, free spins are available for new players at VoodooDreams, Duelz, LuckLand, Buzz Bingo and Spin Rio.

Only slot machines can be played with free spins, but this bonus usually comes with very strict game restrictions. It’s likely that a free spins bonus will only be eligible on one game; in the best case scenario, casinos offers players a choice of five slot games. Starburst, Book of Dead and Aloha! Cluster Pays are three popular options for casinos.

Cashback bonuses are less common, in which casinos offer to return a portion of lost bets, usually on a weekly basis. The amount tends to be small, such as 10% on losses under £10.

From our list of the best payout slot casinos, only All British Casino currently offers cashbacks. Game eligibility is irrelevant here, since you’re recouping funds at the site, as opposed to spending them.

A reload bonus is one that rewards returning customers for making a deposit into their casino account. For instance, you might receive 20 free spins on Big Bass Bonanza in exchange for a qualifying deposit of £10.

By definition, reload bonuses are for existing customers, so you’ll need to sign-up to a casino in order to receive one of these offers. Reload bonuses are often targeted to individual players, so at the best payout slot casinos, offers could target games with high RTP percentages if they’re regularly played.

The best UK online casinos will offer no deposit bonuses, whereby players can sample the games entirely for free. There’s no need to make a deposit, but restrictions on what players are able to do with the funds is often heavily restricted. For instance, you’ll likely only be able to spend the no deposit bonus on one slot game.

Watch Out for Wagering Requirements

With any casino bonus, you need to be mindful of the attached terms and conditions. Wagering requirements are one of the most impactful when it comes to the value of a bonus. These requirements prevent you from withdrawing your bonus and resulting winnings until they’re completed.

Typical wagering requirements are set at around 35x the bonus. So if you claim a matched deposit worth £10, you’ll need to wager £350 (£10 x 35) in total before the bonus and any related winnings can be cashed out. For free spins, these requirements are typically applied to any resulting winnings — so if you won £5 using free spins, the wagering requirements would be £175 (£5 x 35) in total.

Games Restrictions

If you’re intending to use a slots bonus to play games with the best payouts, keep in mind there could be restrictions on certain titles. This is often the case when it comes to slots with high RTP — you can find the full list of exclusions within the bonus terms and conditions.

Other T&Cs

Best Payout Slots – Ways to Win

Working out the number of ways to win a slot game predominantly comes down to three features: its paylines, its multiplier symbols, and its bonus rounds. Below we break down these features and explain how they affect player payouts. 

Paylines

Paylines refer to winning combinations of symbols across the reels. The very first mechanical slot machines had just one payline that paid out when players landed three identical symbols in one horizontal line.

During the early days of online gambling, developers of slot games stuck with simple playlines, but as technology improved, more and more reels and rows were able to be introduced to their slots, raising the potential number of paylines.

These days, you can play slot games with numerous potential paylines that cover different patterns across the reels. In fact, thanks to the invention of slot mechanics like Big Time Gaming’s Megaways framework, some of the best payout slots boasting hundreds of thousands of ways to win.

Multipliers


Another way in which payout opportunities increase is through the use of multipliers. These might feature in the base game of a slot or during a bonus round, boosting any potential winnings according to the value of the multiplier.
Multipliers can show up in a multitude of ways in the best payout slots. They’re often attached to other features in the game. Let’s take a look at a few examples.

Gonzo’s Quest by NetEnt popularised the Avalanche Reels feature found in many games today. Every time a winning payline is created, it’s blasted off the board and replaced with new symbols. At the same time, the win multiplier increases by one. The more wins you chain, the bigger your multiplier, amplifying your payout.

Jammin Jars 2 by Push Gaming uses the Cluster Pays mechanic rather than traditional reels. Much like Avalanche Reels, winning clusters disappear from the grid to make space for new ones. If you land a Jar wild symbol in your combination, a multiplier is applied to the win which increases for every cluster.

Bonus Rounds


Many slots increase a player’s chances of winning through bonus rounds, where players might be presented with an entirely new game altogether. Bonus rounds may include multipliers, free spins, increased wilds, expansion symbols, and other unique payout opportunities. 
With slots fans always on the lookout for something new and exciting, there are plenty of games on the market with thrilling bonus rounds. Examples include:

Head out to the Tropics and experience the dinosaurs as you’ve never seen them before: shades on and with a piña colada in hand. This 7x7 slot developed by Relax Gaming comes with a great soundtrack to match the beautifully designed island paradise. A mix of different dinos and eggs fills the reels, and these will be replaced by new symbols after every win thanks to the avalanche feature. Land two of the Jurassic Party scatters and you’ll receive two re-spins; land three of them and you’re rewarded with seven free spins. Before these free spins start, you’ll be taken to the beach hut to take part in a cocktail picking game, enhancing the potential to win big during the bonus spins. Wilds will stick in place on the reels until they pop in a winning combo, and players should look out for the wayward beach ball — this adds a multiplier value to each of the wilds on the board. With an RTP of 96.5%, this is definitely the party to be at, and one of the best payout online slots we’ve seen for years.

Pragmatic Play’s Drill That Gold takes players deep within the mines of the United States. We love this game’s fantastic country soundtrack, which provides the perfect accompaniment to the action. Players can receive six, eight, or ten free spins when landing three, four, or five bonus symbols on the reels. During this free spins bonus round, a golden drill will expand to fill one of the reels and improve your odds of winning, and this round can be reset if you’re lucky enough to find more bonus symbols. When a stack of miners lands on one reel, our hard-hatted friend at the side of the screen will jolt into action, turning the stack into one big drilling wild. With an RTP of 96.5%, this high volatility slot comes with 20 paylines and a max jackpot of 5,000x the stake.

Moon Princess 100 is the anime-inspired sequel to the original Moon Princess slot, which was released back in 2017. Play’n GO has retained much of the design of the original game, with wins on the 5x5 grid made possible by the cluster pays engine — this means players can earn prizes when they land three or more identical symbols either vertically or horizontally. The game’s three princesses have the power to reward any non-winning spin according to their own ability: Storm will remove and replace any two sets of symbols; Love will transform one symbol into another; and Star will add one or two wilds to the reels. As well as this, the Princess Trinity meter to the side of the grid will be filled when combos are made with one of the three princesses. Once it’s filled, players have the chance to launch the free spins bonus round. Moon Princess 100 is another highly volatile slot that comes with an RTP of 96.2%.

Big Time Gaming teamed up with IGT for this TV-inspired slot title. The base game delivers the standard 117,649 different ways to win via its six reels, but in the free spins feature, players can land an expansion icon that increases the number of symbols on the reels. It’s incredibly unlikely to occur, but if players manage to expand the number of symbols to their full amount of ten per reel, Wheel of Fortune then becomes a slot with an eye-watering one million different routes to payouts. With the chance to win 80,150x your stake, and an RTP of 96.5%, this slot is high risk, high reward.

Slip on your balaclava and tiptoe your way to cash prizes in Midnight Marauder – a 6x6 Relax Gaming slot with a top win of £900,000. This slot also adopts the cluster pays engine, paying out when players land five or more symbols next to one another on the reels. The best thing about this slot is that every win will be granted with a re-spin, allowing for players to build huge combinations. If the cluster you’ve already hit collects more of the same symbol, they’ll be added on to the multiplier value: collecting five is a 5x multiplier, and so on. Land three of the robber bonus symbols and you’ll launch a round of ten free spins that take place next to a sleepy museum guard.

One spin of this slot and you’ll get a flavour of what Johnny Cash was slandering in his immortal live prison shows. Nolimit City hasn’t sugar-coated anything here – this is a bleak representation of life behind bars, with a gritty soundtrack, images of electric chairs, and convicts who look deserving of their place. There are 46,664 paylines available on this slot, but first you’ll need to unlock certain spaces on the grid; if you manage to do so, you’ll open yourself up to the possibility of landing the max jackpot of 75,000x the stake. Each time you land one of the golden Folsom scatters, two of the positions on the reel will open up. If you hit three of these scatters on the middle two rows, you’ll trigger a round of eight free spins. Walk the line and electric chair bonuses can also be unlocked, and the cockroach feature will grant players multipliers on their wins.

Castle of Terror is a spooky new 6-reel slot from Australia-based Big Time Gaming. It is a highly atmospheric title with some impressive graphics and a menacing soundtrack. However, in truth, Castle of Terror’s only really terrifying when you’re losing, as it sometimes depicts some rather picturesque scenery and becomes suitably jolly whenever you trigger a big win. Up for grabs in the castle are free spins, progressive win multipliers, win exchanges and a truly frightening max payout of x61,720. Of course, you’d need a miracle to pull that off, but Castle of Terror still carries a decent RTP rate, and there are a staggering 4,096 ways to win.

If you’ve played SYNOT’s 81st Cabaret, you’ll be familiar with the format of this sequel. Like its predecessor, 27th Cabaret allows players to step inside La Belle Époque of bohemian music halls and burlesque dancers, except now these splendours are revealed across three reels rather than four. 27th Cabaret is a medium volatility slot that has 5 paylines and Expanding Wild symbols that give you a better chance of winning and can be activated in, you guessed it, 27 different ways. Both the variance and maximum possible win – which stands at x500 – of this slot is lower than some of the others mentioned on this page, making this a slot game more suited to low rolling players looking to have some fun.

Payment Methods for the Best Payout Slots


Here are some of the payment methods you can use to make deposits and place wagers on the best payout slots. 

Name Availability Deposit speed Withdrawal speed Description Pros and Cons
Excellent
Deposit speed

Withdrawal speed
3–5 working days

Debit Cards

All of the UK’s best payout slot sites will accept debit card deposits. For most players, it’s the most familiar way to pay online — just tap in your 16-digit card number, expiry, and security code. Payments via debit card are secure thanks to the latest encryption methods used at licensed casinos. You can also rest assured that depositing with this method will qualify you for any bonus offers. 

Counterbalancing these perks is the fact that you’ll need to wait a while for your withdrawals, usually between 3–5 working days. Visa Fast Funds users, however, can expect to receive their withdrawals as quickly as e-wallet users — within roughly an hour of the request being processed.

Pros
  • Simple and familiar to most players
  • Available at every site
  • Always eligible for casino bonuses
  • No fees to use
  • Deposits are instant
Cons
  • Slower withdrawals than other methods
  • Requires sharing bank details with the casino

e-Wallets

e-Wallets such as PayPal, Neteller, and Skrill represent the UK’s most popular options in this category. With deposits requiring no exchange of bank information, lightning quick withdrawals, and great security, it’s easy to see why e-wallets are a trustworthy payment method. Simply sign up for an e-wallet account and you’re ready to go — all you need to make a casino deposit or withdrawal is your email address and password.

One thing to note is that due to the heightened potential for bonus fraud, e-wallets can often be excluded from casino bonuses. Some e-wallets such as Neteller and Skrill also have small fees attached to moving money in and out of the account. Make sure you’re happy with these charges if you’re considering using these services.

Pros
  • Store all your payment cards in one account
  • Widely supported
  • No need to share bank details
  • Free to sign up
  • Fast withdrawals that are often instant
  • Additional features and benefits
Cons
  • May be small fees attached
  • Often excluded from bonuses

Trustly

Payments intermediary Trustly uses Open Banking technology to let users transfer money directly to and from their casino wallet. There’s no need to create a separate account to use the service — simply log in with your usual online banking credentials. 

Deposits land instantly, and withdrawals via Trustly usually arrive within a day or two but often much faster. It’s usually valid for claiming a casino bonus too. While most casinos won’t charge you for Trustly payments, watch out for fees which may be levied by your bank. 

Trustly is a favourite of ours at TopRatedCasinos.co.uk, with peerless speed and security that’s magnified by Pay N Play, a service that lets you effectively skip KYC processes at participating online casinos.

Pros
  • Highly secure
  • No need to sign up
  • Instant deposits and withdrawals
  • Usually eligible for bonuses
Cons
  • Not available at all sites

Paysafecard

Paysafecard is a prepaid card service that allows users to purchase vouchers at participating retailers. The funds can then be transferred to your casino account using the printed 16-digit PIN. Only preloaded funds can be spent, which means users can keep a tight watch on their budgets. It’s also a great option if you’d rather keep your banking details private. 

There are a few drawbacks to this payment method. Withdrawals are not supported, so you’ll have to provide alternative credentials when you’re ready to cash out. As Paysafecard vouchers are only available in denominations of £10–£100, it may not suit high rollers. It’s occasionally excluded from claiming welcome bonuses too.

Pros
  • Make casino deposits with cash
  • Useful budget management tool
  • Strong security and privacy
  • Deposits land instantly
  • Sold at thousands of retailers nationwide
  • No fees
Cons
  • Withdrawals not supported
  • Tight spending limits won't suit every player
  • Sometimes excluded from bonuses

Pay by Phone

Pay by phone services like Boku and Payforit let players make quick and easy casino deposits using just their phone number. Simply key in your number and confirm the deposit via SMS. The amount will then be charged to your monthly contract or taken from your PAYG balance. There’s no need to share any bank details with the casino.

As with prepaid cards, this option can’t facilitate withdrawal requests. There are also strict limits of £30 a day, so it likely won’t suit high rollers. 

Pros
  • Instant deposits using just your phone number
  • No need to share bank details
Cons
  • Daily and monthly spending limits won't suit all players
  • Often fees attached
  • Withdrawals not supported

AstroPay

One newer payment method you might find when you play best payout slots online is AstroPay. This service works much like a digital wallet such as PayPal, but with an additional benefit: the ability to generate virtual prepaid cards. Essentially, that gives players all the advantages of a service like Paysafecard — namely top security and strict budget management — with the functionality of an e-wallet. Unlike Paysafecard, you can request withdrawals to AstroPay. From there, the money can be sent to your bank account or used to top up your next virtual prepaid card. 

AstroPay offers a free mobile app for management of your account on the go, and you can also use the service to buy and hold cryptocurrencies. There aren’t many drawbacks to using AstroPay at online casinos — perhaps the only issue is that it’s not yet found at that many sites with best payout slots. That said, support for this service is increasing all the time. 

Pros
  • Make secure deposits with virtual prepaid cards
  • Fast and instant withdrawals
  • Additional e-wallet functionality
  • No fees to sign up or use
  • Useful budget management tool
Cons
  • Not yet widely available
  • May be excluded from bonuses

Cryptocurrencies

Cryptocurrencies like Bitcoin and Ethereum offer an alternative way to pay for goods and services online. The advantages are many: since crypto is a decentralised form of currency with transactions recorded anonymously on a public ledger, it’s highly secure and there’s low risk of fraud. Payments are also lightning fast, both for deposits and withdrawals. In fact, you’ll often receive your money instantly when you withdraw to a cryptocurrency.

But cryptocurrencies aren’t without their drawbacks. Bitcoin often finds itself in the news due to its volatile price which can fluctuate dramatically. There are also some small fees associated with crypto transactions. In any case, it’s essential to do plenty of research before considering this payment method at slots sites. Another disadvantage is the lack of support — you won’t currently find crypto as an option at many sites with best payout slots. However, more widespread availability is being seen as time goes on. To get started with this method, you’ll need a free crypto wallet to store your funds.

Pros
  • Transactions often settle instantly
  • Strong levels of security and privacy
Cons
  • Not widely available
  • Some small fees attached
  • Cryptocurrencies can be volatile

Responsible Gambling

Although RTP percentages are a helpful indication of a slot’s average payout rates, players must remember that these figures are purely theoretical. Developers arrive at RTP rates by simulating their slots millions of times over, so it’s likely that your own playing experience will deviate significantly from the advertised rate. 

There’s a dangerous and faulty line of thinking in gambling that luck must turn during a losing streak. But casino games function on probabilities, and in reality have little to do with luck. Even when playing the UK’s best payout slots, there is never a guarantee that you’ll win money. 

You should never treat your gambling habits as an investment expecting a certain return. If we always knew what we stood to win from the spin of the reels, gambling in this form wouldn’t be much fun, and entertainment should always be gambling’s primary function. 

If you’d like to know more about how to gamble responsibly and the warning signs of gambling addiction, click through to our dedicated responsible gambling guide, or visit our Before You Play hub. 

  • No matter whether you’re playing the best payout slots or enjoying a traditional table game, gambling responsibly is essential. Here are some of our top tips:

    • Set your budget – Before you play, decide an upper limit for what you want to spend. Once you hit this amount, it’s time to call it quits.

    • Use on-site limiters – All licensed casinos must provide limiters so players can control how much time and money they spend on gambling. It’s a good idea to set these up once you register at a site.

    • Don’t chase losses – You’re never ‘owed’ a win, even when playing a best payout slot. This goes hand in hand with sticking to your budget.

    • Only gamble when sound of mind – If you’ve consumed drugs or alcohol, or are feeling emotional, it’s not a good idea to gamble. Your judgement will be impaired, which makes it harder to gamble responsibly.

    • Seek help if you need it – Feeling worried, anxious, or ashamed about your gambling habits? Don’t hide it from friends and family, and make sure to get help from a gambling organisation or charity.

  • Need some advice or support with your gambling? There’s plenty available — here are just a few organisations which can help.

    • GamCare – Access responsible gambling resources, speak with an adviser via live chat, or contact the freephone 24/7 National Gambling Helpline on 0808 8020 133.

    • Gamblers Anonymous – Attend meetings and support groups to help with your gambling.

    • BeGambleAware.org – A comprehensive resource for responsible gambling.

The Best Payout Slots Summarised

High payout slots are great for those looking for the best RTP rates, but they won’t be to every player’s taste. Here’s a brief round-up of the reasons for and against playing these slot games.

Pros
  • Play slots with the highest RTP rates – The best payout slots will offer the best RTP percentages of any slot games, so will in theory offer frequent prizes, but remember that any one session can provide big fluctuations in the advertised figure
  • Sample the best game developers – All of the industry's best slot developers have created high payout slots, so you can enjoy a varied experience when playing these games
  • Enjoy slots across a range of styles – High payout slots can take many different forms – from classic slots with one payline, to Megaways titles with hundreds of thousands
  • Make use of bonus features – Many of the best payout slots will deploy a mix of in-play bonus features, such as multipliers, wilds, free spins, picking games, and additional bonus rounds
  • Suitable for players with small budgets – Since these slots pay out at increased rates on average, players can often spin their reels with small wagers – sometimes as low as a penny
  • Play on mobile – The best payout slots are all mobile compatible, so you can spin the reels on the go
Cons
  • Frequent but small wins – Most high payout slots compensate for the frequency of their payouts by issuing small amounts when players win
  • Strict game weightings – Since high payout slots offer players frequent wins, online casinos often limit contributions to the wagering requirements – check the terms and conditions for a full breakdown of game weightings
  • No guarantee of winning – Although your chances of winning on a high payout slots are increased, there are never any guarantees in gambling

Frequently Asked Questions

  • It’s unlikely. Pretty much all casinos limit welcome bonuses like free spins to certain titles, and these often exclude progressive jackpot games and the highest paying slots. You’ll still be able to use your spins on top online slots with respectable RTPs, though. For example, NetEnt’s Starburst has a payout rate of 96.1% and is one of the most popular slots for free spins bonuses.

  • Yes, if you want to play these games for real money. Luckily, our recommended best online casinos offer a range of fast and secure banking options including PayPal, Neteller and Skrill, so you have plenty of choice. Most sites offer free demo slots so you can play slots for fun, but progressive jackpot games are often excluded.

  • The best paying online casino is the site which pays out the most to players on average, but there’s no easy way to check this. If you’re looking for the best payout UK online casino, you should check out the games library to see which sites offer the largest number of the highest payout slots.

  • Yes. Casinos often partner with different software developers, so the games on offer vary, but you can play high RTP slots at the majority of new casino sites. Some of the best payout online slots in the UK, like Goblin’s Cave, aren’t as widely available as other games, so you may have to search a bit harder to play certain titles.

  • If you land a win on the best RTP slots and withdraw your returns, head to the cashier page, enter in your chosen amount and hit request. Make sure to read up on withdrawal limits and processing times- check out our fast payout casinos for instant withdrawals.

  • No – licensed casinos frequently have their games audited by industry regulators such as eCOGRA. If a casino site is caught manipulating the payouts of its games, it will face significant fines, and may even have its licence revoked.

  • No – there’s no difference between playing online slots at night or in the day.

  • Payout rates are determined by the content of the slot. If a slot has a simple structure – say only three reels and five paylines – then there are only five avenues in which players can win money. More expansive slots, such as Megaways titles, are packed full of additional features that increase the opportunities for payouts.

  • It’s difficult to pinpoint the slot developer with the highest average RTP percentages, but NetEnt is certainly up there. Three of its creations — Mega Joker (99%), Jackpot 6000 (98.9%), and Blood Suckers (98%) — all rank in the top ten best paying slot games.

  • Wilds, scatters, and free spins are bog standard bonuses within slots, but we like to see games with their own dedicated bonus rounds, such as Jurassic Party and Rainbow Riches.

  • Thankfully a slot’s RTP is always clearly displayed, as all licensed online casinos have to make the information easy to find. The RTP will most likely be found on a slot’s information page, or even on the main page of your selected casino. They typically list the games available on their site, and include details such as RTP so you can make an informed decision on which game to play.

  • There’s no objective answer here. While the best payouts can often be found on slots with high RTPs, choosing the best app depends entirely on your needs and priorities. Check out our guide to mobile gambling apps to find your perfect match.

  • RTP (Return To Player) is the percentage of all the money wagered on a particular slot game that is paid back to players over its lifetime. Variance – or volatility – on the other hand, refers to the frequency and size of a slot’s payouts. For example, a low volatility game is likely to give out smaller amounts of money more frequently, whereas a highly volatile or varied slot game will payout less frequently, but with higher amounts. 

  • No. While a high RTP slot gives you a better chance of receiving a payout, there are never any guarantees in online slots. 

  • Demos of the vast majority of high RTP online slots can be played for free, but you won’t be able to win any money. Also, if you have been awarded some free spins, these can usually be used on high RTP online slots. However, any winnings you might gain from free spins will almost always have to be wagered a number of times before you can withdraw any real cash, and sometimes they can only be used on certain titles. Make sure you double check the terms and conditions of your free spins to see what your wagering requirements are and which slot games are eligible.

  • No. Use of credit cards for gambling was banned by the UK Gambling Commission in April 2020 as part of its harm reduction strategy. However, there are plenty of other ways to make a deposit at casinos with best payout slots. Debit cards are a familiar option for most, while e-wallet services offer additional functionality and tend to be the quickest for withdrawals.

Blacklisted Casinos

If you’re looking for an online casino with the highest-paying slots, avoid the blacklisted names below — there’s a host of reasons they could end up on this list. First and foremost is lack of licence, an important consideration when finding a legitimate casino. Operators who act in ways contrary to licensing requirements will always find themselves blacklisted, and that could include rigged games, unclear T&Cs, or poor security standards.

Finding a slots casino with the best payouts is all well and good, provided they actually pay out. Operators who make it difficult to access your cash — either through a convoluted withdrawal process or limited payment methods — will quickly find themselves on our blacklist, as will those with any reputation of not paying out at all. The names below are blacklisted for some of these reasons, and you’re taking a big risk if you choose to play at them.
