Online Slots Guides

Our comprehensive guide explains how to play slots, what each of the common terms mean, and what to look out for from each game.
High Variance Slots
One of the humble slot's most curious qualities is variance, or volatility. Our guide breaks the concept down and explains how it affects a slot's behaviour.

How to Find the Best UK Slot Sites

We research and review every slot site that is available to UK players to ensure you know the best choices for you. Here’s how you can find the best UK slots site for you (all the information you need is in our reviews!)

STEP 1
Check the Casino Has a UKGC Licence
We only recommend UKGC licensed sites. It’s a legal necessity and guarantees safety and security.
Know Your Customer KYC Casino Compliance STEP 2
Check the Range of Slot Games on Offer
The best slots sites offer hundreds, often thousands of excellent slot games.
Casino FAQs STEP 3
Review Slot Game RTPs
Slot RTP is important to know, 96% is the average, anything above that is great.
STEP 4
Sign Up, Claim your Bonus, and Play!
Once you’ve found the slot site for you, sign up and claim your welcome bonus.

How to Get Started

While multiline video slots might first seem a bit daunting to new players, it’s actually pretty easy to get the hang of this casino classic. Whether you’re playing slots for fun or to win real money, here’s how to play.

  1. Read our expert reviews
    Use the list of top casinos to compare the very best places to play slots online. We’ve highlighted bonus offers along with the key terms to help you find your perfect match. Want to delve a bit deeper?
    Check out our expert casino reviews to find out everything you need to know about a slot site, from games libraries to banking options and everything in between.
  2. Sign up
    Once you’ve settled on a top slot site you can follow our link to head straight to the sign-up page. It only takes a few minutes to create your account, and you’ll need some basic personal details, including your name, address and email.
    You’ll also need to provide information for the casino to verify your identity, though the exact process will vary between sites. Like the look of the welcome bonus? Check the terms and conditions before you opt in to claim your free spins or matched deposit reward.
  3. Deposit
    You’ll need to make a deposit if you want to play real money slots online for real money. Head to the cashier and select your preferred payment method- most online casinos offer a range of banking options, from debit cards to e-wallets like PayPal. Your welcome bonus rewards will normally be credited to your account after this deposit.
  4. Play
    Now there’s only one thing left to do: hit spin and hope the reels land in your favour. If you do land a lucky symbol combination, you’ll be able to cash in on your returns or use any winnings to play again. Enjoy!

Pros and Cons of Playing at the Best Online Slots Sites

Here are some benefits and disadvantages of opting to spin the reels at UK slot sites.

Pros                                                               

Easy entertainment – slots can be great fun, and they’re often stimulating experiences thanks to their themes, graphics, bonus rounds, and sound effects. Note that slots should always be an avenue for fun and never for turning profit, no matter how good a win feels or how much you might believe your luck is in;

Accessibility mobile apps, lightning-fast desktop sites, and OS-agnostic performance means you can take spin the slots any time, anywhere;

Thousands of options – take a look at any slot site’s library and you’ll see there’s no shortage of choice out there, no matter what kind of theme, variance, or limits you’re looking for;

Free spins – whether they’re courtesy of the slot site or earned through play, you’re bound to snag some free spins on the slots with an equal chance of winning to paid wagers;

Jackpots – if you’re one of the luckiest players, you could land a big win on the slots. Progressive jackpots are even more tantalising, with lottery-style odds of winning reflected by lottery-sized payouts;

Top developers – the best slot sites are packed with games from the best slot developers, from NetEnt to Microgaming and Yggdrasil;

Player choice – no matter if you’re a PayPal depositor, a penny slot fan, or someone interested in player-versus-player tournaments, the best slot sites are set to deliver.

Cons                                                              

Convenience – slot sites’ ease of access can be a problem if you’re a problem gambler or addict. We’ve got advice and sources of support below if you or someone you know is suffering from problem gambling;

Volatility – while volatility isn’t a problem in itself, not knowing what kind of slot volatility you’re playing with can be a disadvantage. Some slots have variable volatilities, too, but it can be hard to find concrete information on what to expect from an individual slot;

Payout speeds – not every site offers fast withdrawals unfortunately, so be sure to take a look at the slot site’s T&Cs if you’re interested to know how long it takes for payouts to be processed.

How We Review UK Online Slots Sites

There’s an abundance of places to spin the reels online, and you’ll need to consider a few factors when it comes to comparing slot sites.

Licensing

The UK’s gambling scene is regulated by the UK Gambling Commission (UKGC), and it’s this body that awards gambling licences to sites and operators both online and at land-based venues.

Every site ranked and reviewed on TopRatedCasinos is licensed by the UKGC, meaning you can be sure that every slots site listed here meets its strict standards and guidelines.

To land a licence, slot sites are subject to regular audits focused on game fairness, they must behave ethically and enact measures that drive responsible gambling, and all customer transactions must be encrypted for added security.

Casinos must also implement anti-fraud and anti-money laundering measures to gain and retain a UKGC licence.

Slots draw particular attention during game audits as they must have provable randomness, and they must match the RTP advertised too. This ensures that the games you’re playing aren’t rigged against you.

Games Library

No one wants to sign up to an online casino only to find that it’s missing their favourite title, so check out what’s on offer before you sign up.

Most slot sites let you browse their range of games before you create an account, so you’ll be able to see the video, classic and progressive jackpot slots on offer.

You’ll also be able to check up on a casino’s software partners, which is worth doing if you’re a fan of a particular developer’s slot selection.

However, it’s not just slot games that you should look out for — take a look at which other casino games are on offer.

You can never have too much variety when you’re seeking out a new slots experience, and the very best UK slots sites will have filterable search functions to help you separate the wheat from the chaff.

Bonus Rewards vs Bonus Terms

Biggest isn’t always best when it comes to casino welcome bonuses. 100 free spins may initially seem more attractive than 20 free spins, but higher wagering requirements and lower win limits could mean you’re better off going with a smaller bonus.

Be sure to familiarise yourself with the bonus conditions before you opt-in, and select one that suits your experience and games preferences.

Banking Options

The best UK slot sites offer a range of banking options, from bank cards to e-wallets and everything else in between.

Keep an eye out though — the likes of Paysafecard deposits and pay by phone bill payments aren’t available at all slot sites. You should also know that some payment methods, particularly Neteller and Skrill, aren’t always eligible for welcome bonuses.

To help you out, our reviews make it easy to see which banking options are on offer at each site.

Mobile Compatibility

If you want to play slots on your mobile phone, you’ll need to consider how easy it is to do so. Are you happy to play via your mobile web browser, or would you prefer a mobile slots app?

The very best mobile experiences are found on dedicated smartphone apps, but it’s important to remember that they’re still a little uncommon for all but the biggest online casinos.

Withdrawal Terms

Terms and conditions don’t just apply to bonuses. You need to check how easily you can access your winnings too as pending times and withdrawal limits vary between sites.

If getting access to your cash quickly is important to you, be sure to compare withdrawal banking options, processing times and minimum withdrawal limits when you’re picking your favourite slot site.

Customer Support

Chances are that you’ll probably never need to use a site’s customer services, but it’s good to know they’re on-hand when you need them.

You’ll need to check the opening times, as well as how you can get in touch. The best UK slot sites offer round-the-clock support via telephone, email, and live chat.

Slots Tournaments

The best UK slot sites host regular tournaments for their members. These tournaments pit casino players against one another in a bid to win cash or other casino-related prizes. It’s an excellent way to promote new slot releases, stimulate some added competition on-site, and provide members with an extra layer of excitement.

Slot sites hosting these tournaments will allocate a prize fund for successful players, ranging anywhere between £100 and £10,000 for first place. Finishing in the top three or five is often good enough to qualify for a reward, but this will vary with each online casino. Players should also note that there may be an entry fee, particularly if the top prize is on the heavy side!

Here’s how slots tournaments work: the casino will nominate one of its most popular slots to feature in the tournament, publishing a leaderboard of each participant’s results. It’s simple – the more lucrative your spin of the reels, the better your score, and the higher you’ll rank on the tournament leaderboard. Once the tournament timeframe is up, those who qualify for a prize will be able to claim it.

Of course, as slots are purely games of chance — unlike poker, for example — there are no special tactics that players can deploy to help them win, but that doesn’t stop these tournaments being great fun.

Tournaments are hosted by plenty of UK slot sites — some of our favourites include those at Race Casino, Duelz, and Regent Play.

Online Slot Game Variations

Slot games come in all shapes and sizes; these are the three main categories:

Classic SlotsSlots icon

If you’d rather keep things simple or simply prefer games modelled after classic slot machines, there are plenty of classic slots on offer at the UK’s best slot sites.

These are 3-reel games that usually feature 1 to 5 paylines, and are a great place for beginners to start. For those after some casino nostalgia, expect classic fruit and seven symbols that take you back to the days of traditional fruit machines in brick-and-mortar casinos and arcades!

Just about every casino software developer has a few classic slots in the locker, so you can play them at all the best online slot sites.  IGT, which made its name making land-based slots back in the 90s, is particularly well-known for online classic slots like Triple Diamond, while the likes of Microgaming has also made top titles like Break da Bank.

Video SlotsVideo Slots

Video slots can have a number of different reels and make up the vast majority of games at the best slot sites.

These variations have risen to the top of the charts thanks to their combination of entertaining pop culture themes, vibrant animations, HD graphics and an array of fun symbols.

Most also spice things up a bit with exciting bonus features, such as wilds, scatters, multipliers, free spins and bonus rounds, which add to the fun.

Many video slots also feature multiple paylines, with some offering over 1,000 ways to win. Software developers are constantly vying to produce the most innovative video slots on the market, so there’s no end to the exciting possibilities.

Progressive Jackpot SlotsProgressive Jackpot slots icon

Progressive jackpot slot games are popular among so many slots enthusiasts.

These increase every time someone places a new wager, meaning that certain slot titles, like Mega Moolah, have jackpots that can rise well into the millions.

Many progressive jackpot slots require players to make the maximum bet to win the full jackpot, but those with more modest budgets aren’t excluded from winning big.

Slots like Mega Moolah have tiered jackpots that are often released at random, so there’s still the chance to land a sizeable windfall.

Progressive jackpot slots are usually high variance, too. This means that while they offer big prizes, they don’t pay out often-so you could very well run through your bankroll before you get a shot at triggering the jackpot.

However, if you don’t mind taking a risk for the biggest prizes on the market, progressive slots might be right up your street.

Real Money Slot Sites

While you don’t have to deposit to play at any of these UK slot sites in May 2022, you’ll have to play real money slots to be in with a chance of winning real money.

This doesn’t mean you’ll need a huge bankroll though —  you can play penny slots for just 1p per spin, while many other titles have relatively low bet limits. On the other end of the scale, maximum bets for large progressive jackpot slot games can go well into the hundreds, so there’s a wealth of real money slot games for high rollers out there too.

If you’re keen to aim for some cash winnings from your spins, play slots for real money.

Regulations have come into force in recent years, however, which mean you’ll need to register at a slots site and verify your age before playing. Provided you’re over 18, this shouldn’t be a big hurdle to clear.

Real Money Slots vs Free Slots

There are pros and cons to both real money slots and free slots, but ultimately the one that’s right for you depends on what you’re looking for from a slots experience.

Free slots, whereby you can spin without wagering any of your own cash, are a great way for beginners to get accustomed to slot features without any risk. They’re ideal for beginners easing their way onto the slots scene, and they give you a chance to familiarise yourself with pay tables and bonus features before trying out real money slots.

Once you’re up to speed with bonus rounds, multipliers, cascading reels, and other slots features, you’ll be well set to try your hand at real money slots.

While there’s considerably more of a rush to be had from winning paylines that dole out real money, there’s plenty of fun to be had with free slots.

Real money slots, however, are where you’ll find the true slots experiences. Not only do these slots tend to be more lovingly developed and feature-rich, but they also come in more varieties and themes.

Progressive jackpot games, thrilling bonus rounds, and the ‘one-more-spin’ tease will have you coming back for more whilst offering the chance to win real money prizes.

Some sites make it tough to identify the free slots options in their selection, but you should be able to locate them either through the site’s filters or by searching ‘free’ in its search bar.

How to Play Slot Games Online

While multiline video slots might first seem a bit daunting to new players, it’s actually pretty easy to get the hang of this casino classic. Whether you’re playing slots for fun or to win real money, here’s how to play.

  1. Check the paytable
    A paytable shows you how much you can win depending on your bet, and your minimum and maximum stake options. Some use ratios to show the best payout slots, while others use percentages or multiplier values, such as x3.
    You’ll also be able to check for the game’s bonus features, such as multipliers, to see if there are any other ways to maximise your winnings.
  2. Set your stakes
    In many slot games, players will bet with ‘coins’ that have a real currency value. The value of these coins are set to a certain value in some games, while others allow you to set this yourself. Make sure your coin value suits your bankroll- you don’t want to run through your budget in the first few spins.
  3. Select your paylines
    Most slots feature multiple paylines, and betting on more lines can increase your chances of landing a win. Remember that the more paylines you bet on, the more you’ll wager, so don’t get too carried away!
  4. Hit spin
    You can hit spin once you’re happy with your wager- it really is that easy. You’ll certainly know about it if you do strike lucky – a message usually flashes up on the screen, along with some celebratory music. If you’re playing for real money, your winnings will be credited to your casino account.

Online Slot Game Mechanics and Features

It’s not just online slot sites that boast rewards, many individual slot games also feature a variety of in-game bonus features to boost your gameplay. These are the most common:

Wilds

Wild symbols act as a substitute for other symbols to increase your chances of landing a winning combination.

Stacked Wilds

These wilds stack up on top of each other and can cover entire reels, giving you even more opportunity to bag some returns.

Expanding Wilds

As the name suggests, these wilds expand to substitute other symbols across the reels to create more winning opportunities.

Sticky Wilds

Sticky wilds stick to the reels for a certain number of spins, so you’ll have a better chance of a win on the next turn.

Scatters

When a scatter appears on a reel it can unlock features such as free spins, bonus rounds or minigames for added excitement— and hopefully winnings.

Multipliers

These highly sought-after symbols increase your winnings. The more multipliers you land on a winning combination, the more you’ll win.

Avalanche Reels

Players hunting the thrill of chained or consecutive wins should look no further than avalanche reels — also known as collapsing reels, tumbling reels, or cascading reels — an exciting mechanic found in certain slot games. 

When you land a win on a slot with normal reels, that’s usually it: you collect your win and spin again. In games with avalanche reels, however, winning combinations are instead removed from the reels and replaced with new symbols, potentially completing another payline — which would also be removed and replaced with new symbols and so on, potentially adding up to some huge rewards. All that’s needed is that single first win to set off the so-called ‘avalanche’ that gives the mechanic its name. 

Players love avalanche reels because, frankly, they’re just great fun. The chance to end up on a serious streak all from one spin is a hair-raising prospect, and even smaller wins can be boosted if they result in a chain. 

So, where did this compelling game mechanic originate? The first title to feature avalanche reels was one of NetEnt’s now best-known slots, Gonzo’s Quest, released in 2010 — and that’s possibly why it’s so popular today. Since then, countless releases from a wide array of developers have included the feature in one way or another. Here are a few of our favourites that you’re likely to find at the best slots sites:

  • Gonzo’s Quest by NetEnt – the first title to feature avalanche reels, featuring the cheerful conquistador Gonzo
  • Who Wants to Be a Millionaire Megaways by Big Time Gaming – a six-reel Megaways slot based on the hit TV show, where the cascading reels feature is called ‘Reactions’
  • Gates of Olympus by Pragmatic Play – a six-reel slot with tumbling reels and cluster pays, themed around Ancient Greece
  • Thunderstruck 2 by Microgaming – based on Viking mythology, this slot has avalanche reels as well as multipliers during the Thor free spins round
  • Dynamite Riches Megaways by Red Tiger Gaming – a mining-themed slot with 117,649 ways to win plus the cascading reels mechanic

Online Slots RTP

Before you play online slot games, you should understand how the return to player (RTP) percentage works. In short, the RTP is the percentage of wagers that a slot game is designed to pay out over an extended period of gameplay.

For example, if a slot has an RTP of 90%, you might win back 90p for every £1 you wager on that game.

Most slots have an RTP of over 90%, and anything over 97% can be considered a high RTP. These percentages are set by software developers as they make the game. However, it’s important to understand that the RTP is theoretical, based on an infinite period of gameplay.

This means that, in reality, returns can vary massively, especially during a short period of play.

Slot Variance/Slot Volatility

High RTP doesn’t necessarily mean you have a better chance of winning, or that a slot is more profitable. Slot variance, or volatility, also plays a role in this. Variance refers to the frequency and size of wins for a particular slot.

If a game has low variance, then it is expected to pay out small amounts often. High variance, on the other hand, refers to a slot that pays out infrequently but which can give you more chance of landing a big win when the reels do line up.

For example, while a low variance slot with 97% RTP may payout small amounts frequently, a high variance slot with 92% RTP could pay out less often with, potentially, larger windfalls.

Take a look at our guide to high variance slots for more details.

Low Wagering Slot Sites

As you navigate this page in search of the top slot sites in the UK, be on the lookout for low wagering bonuses. Wagering here refers to wagering requirements, a common condition of online casino bonuses that commit players to staking their deposits a certain number of times over before they can reap the rewards.

Low wagering bonuses limit the influence of wagering requirements, bringing much friendlier terms to the table. For standard bonuses, players can expect to be saddled with requirements anywhere between 25–50x the value of the bonus, but with low wagering offers, these can be significantly reduced.

Let’s give you an example. If you were to accept a deposit match bonus valued at £50, that came with a standard wagering requirement of 30x, you’d need to wager a total of £1,500 (50 x 30) before you could withdraw any of the bonus funds. But if a low wagering bonus brought these requirements down to just 10x, the amount you’d need to wager would immediately shrink to £500 (50 x 10).

The best slot sites also offer their members no wagering bonuses, removing these requirements altogether. Both of these bonus types are highly valuable, but bear in mind that compared to other offers, the monetary values of these bonuses will be smaller.

No Wagering Slot Sites

No wagering bonuses are a player-friendly bonus offered by some UK slots sites, with their key draw being that you don’t need to fulfil any wagering requirements to withdraw winnings made with the bonus funds or spins.

These bonuses tend to be quite small compared to those with wagering requirements attached, but no wagering slot sites aren’t to be sniffed at.

For example, you might get 10 free spins that are wager free. Anything you win from those free spins is yours to keep, provided you haven’t exceeded any winnings cap that may be applied to the bonus.

If there’s a cap on your winnings, anything you win with your bonus above that threshold will be returned to the house.

Generally speaking, if free spins have wagering requirements they’re tied to your winnings from those free spins. Let’s say you won £20 from 10 free spins, with wagering requirements of 35x.

You would need to wager a total of £700 in order to unlock withdrawals. If your free spins were a no wagering bonus, you could simply withdraw your £20 in winnings without having to wager anything extra.

The drawback of no wagering bonuses, as previously mentioned, is that they’ll be considerably smaller than the bonuses you could reap from regular welcome bonuses. If you’re happy to meet the wagering requirements of a more lucrative bonus, no wagering bonuses might not be as worth your time.

Nevertheless, it’s hard not to recommend freebies without the typical strings to cut.

Fast Payout Slots Sites

Fast withdrawal casinos are very popular among players in May 2022, and operators are working to accelerate processing times across the industry. Beyond the online slot site’s internal processing time, which can vary between hours and several days, there are a few other factors in play that impact how quickly you can withdraw your winnings.

Chief among these is your payment method, and the one you choose can have a significant impact on how quickly you can make withdrawals.

Debit cards typically have a lead time of 1-5 working days on top of your casino’s internal processing time, while e-wallets like PayPal and Skrill generally process withdrawals within 24 hours once the transaction has been approved by the casino.

Bank transfers are the slowest method, generally speaking, with some processing times on the bank’s side taken up to a week. 

KYC

Before depositing and withdrawing, you will have to complete a Know Your Customer (KYC) check to confirm your identity and age.

When you do this for the first time, you will need to provide proof of identity, but following that you should be able to complete the checks using your online casino’s database. Ensure you complete any withdrawal KYC checks immediately to avoid any delays.

Finally, your slot site’s working hours can impact the speed of your withdrawals. While you’ll be able to access your casino’s games around the clock, admin staff at the online slot site may only work regular hours.

Therefore, if you make a withdrawal at midnight but the casino’s offices don’t open until 9am, you’ll have to wait until someone’s physically able to begin processing the transaction.

Play UK Slot Demos at TopRatedCasinos 

Along with using bonus credit or free spins, you can also try out a slot for free by playing in demo mode. Of course, you won’t be able to win any real money, but you won’t lose any either.

So, why bother with a slot demo? There are several good reasons:

  • You want to learn how the game works before risking real money, which is especially useful if there are unusual or complex mechanics.
  • You just want to play for fun without the added tension of putting real money on the line.
  • You’ve never played online slots before and want to see if it’s for you.

Fortunately, you can play slot demos demos right here at TopRatedCasinos.co.uk without needing to create an account. First, you’ll have to complete the age verification — it’s a legal requirement of the UK Gambling Commission — by entering your name, address, and date of birth. 

Once successful, you’ll be able to start spinning the reels. If you’re unfamiliar with the game, it’s worth reading the help section beforehand so you understand how the bonus features work. You’ll be given a virtual bankroll to play with and, just like playing for real, you can adjust your bet size between spins. Run out of virtual money? Not to worry — you can restart the game or refresh the page and your balance will be reloaded. And if you decide you’re ready to start playing for real money, why not browse our reviews of slots sites to find your next casino?

Popular Slot Games at UK Slot Sites

There are literally thousands of slots to choose from at UK gambling sites. So much choice can be overwhelming at first, so that’s where we come in — take a look at our recommendations below for some of the best online slots at UK casinos. 

Starburst

NetEnt’s iconic Starburst slot has been on the scene for over a decade, but it continues to prove popular with casino players around the world. Part of its allure is down to its famous win-both-ways payline structure, which allows players to form winning combinations in both directions on the reels. Although Starburst only includes one bonus feature — an expanding wild symbolised by a multi-coloured star — its serene backdrop, calming soundtrack, and dazzling jewels offers players lots of entertainment. Starburst is played on a 5×3 reel and has an RTP rate of 96%. 

Gonzo’s Quest

One of the best things about online slots is that software developers have a blank canvas on which to base their titles. The tales of Spanish conquistadors in the 16th century provides the inspiration for NetEnt’s Gonzo’s Quest, with Gonzalo Pizarro — an explorer tasked with finding the lost city of El Dorado — starring in the leading role. You’ll join him on the reels, which deploy the much-loved avalanche feature that’s become popular in subsequent slots. Players of Gonzo’s Quest, which also has an RTP of 96%, will be able to enjoy plenty of other bonus features as they spin the reels. 

Aztec Falls

If you’re looking for a slot jam-packed full of bonus features, then look no further than Northern Lights’ Aztec Falls. This game features free spins, multipliers, and stacked wilds during standard gameplay; on top of this, lucky players can also trigger the coin fall bonus and the jackpot wheel, where four different jackpot prizes are up for grabs. The biggest jackpot — called the Mega — pays out 5,000x the stake, which could see players land up to £200,000. With an RTP of 96.1%, Aztec Falls is definitely worth a spin. 

Cleopatra

Head to the sultry nights of ancient Egypt and join Cleopatra in this iconic IGT slot. Cleopatra is a high volatility slot, but its reels can be spun from as little as 1p, which makes it suitable for players on smaller budgets. Landing three of the Sphinx scatter symbols will automatically trigger a round of 15 free spins, during which all wins are tripled. With its elaborately adorned reels and authentic soundtrack, players will feel fully immersed in this slot, which comes with an RTP of 95.7%. 

Rich Wilde and the Book of Dead

One of the most popular slots of the last ten years, Play’n GO’s Rich Wilde series takes off in Book of Dead. This slot has an RTP of 96.2% and is regularly targeted by online casinos in their welcome bonuses, which means players can find plenty of free spins to take to this title. The iconography is similar to that of Cleopatra, with the reels framed by ancient Egyptian temples. Rich is predominantly interested in finding the Book of Dead — and you should be too: landing three of them on the reels sets off a round of ten free spins. This symbol also pays up to 200x the stake when it forms a winning combo. 

Primate King

Step into the jungle in Red Tiger Gaming’s Primate King, a 30-payline slot with five reels and an RTP of 96%. We love the look of this slot, as well as its unique approach to bonus features. These features revolve around the collection of coins, which interact with the game’s meter at the side of the screen. Once you collect enough to reach the first milestone, the primate wild will upgrade to a stacked wild; reach level two and this will become a stacked wild multiplier; players reaching level three will see this turn into a sticky wild that triggers a respin.

Doggy Riches Megaways

Another product of the Red Tiger Gaming studio, Doggy Riches Megaways explores the unusual world of canine royalty. The Megaways payline structure means this slot has 117,649 different ways to win and comes with an RTP of 96%. Join the afternoon tea celebrations of this puppy paradise and look for the corgis wilds — not only do these sub in for other symbols to form wins, but if the red and blue corgis land on the same spin, their multipliers will combine and trigger the Queen Spins bonus feature. If this happens, players will be armed with ten free spins.

Viking Fall

Blueprint Gaming’s Viking Fall takes the standard Megways payline structure one step further by generating a massive 262,144 different routes to success. Viking Fall is a highly volatile slot and offers a max payout of 50,000x the stake; with maximum bets set at £10, players could walk away from this slot with half a mil. However, the base RTP of 94% is well below the industry average, so this game is more suited to players on larger budgets. Landing three of the sword scatters will set off the free falls feature, which lights up this slot with thunderous Viking energy. 

Rise of Olympus

Join Zeus, Poseidon and Hades on the reels in Rise of Olympus, a 5×5-reel Play’n GO slot with an RTP of 96.5%. Taking place high above the clouds, this game is famous for its bonus features — we particularly like the hand of God bonus, which triggers at random after losing spins to swap wilds onto the reels. In addition to this, players are given control over the free spins bonus round, selecting one of three gods for varying degrees of volatility as these spins play out. If you manage to fill the wrath of God meter, you’ll receive one of three bonus features.

Raging Rhino

Enjoy the sights and sounds of an African safari adventure in Scientific Games’ Raging Rhino. Leopards, crocs, hawks and gorillas all join the rhinos on the reels, as do diamonds and acacia trees, which serve as the game’s wild. Landing four diamonds will set off a round of 15 free spins, as well as generating wins at 600x the stake. The rewards will become even sweeter if players manage to land five or six of these diamonds. As well as an RTP of 95.9%, Raging Rhino has six reels, 4,096 paylines, and a top win of 1,500x the stake.

Mobile Slot Sites

The simple nature of online slots means gameplay translates well to mobile devices. With so many mobile casino sites, playing slots on your mobile is easier than ever before. Consider these factors when you compare mobile slot sites.

Mobile Optimised vs Designed for Mobile

While online slots used to be made using Flash, the top developers create their slot games using HTML5 these days. This enables smoother gameplay and allows for seamless integration across different devices.

Many software houses have optimised older Flash-based slots, adapting graphics and interfaces for use on touch screens. Nowadays, the very best developers design slot games specifically for mobile use, considering how screen size and touch screens impact gameplay.

Web App vs Native App

Virtually every online casino has a mobile website, which means you can play using your smartphone browser.

However, the very best casinos also offer mobile casino apps. Of course, you can play slot games on both platforms, but native apps can provide higher quality gameplay because they’re developed specifically for the software on your device.

Native mobile apps also have the added bonus of push notifications so you can receive alerts on the latest slots bonuses and newest slots titles as soon as they become available.

You can check out our expert casino reviews to see what each mobile slot app brings to the table.

Phone vs Tablet

Mobile play isn’t limited to smartphones, with tablet devices generally getting access to the same native apps as their smaller counterparts.

Between the two, it’s hard not to appreciate the larger screen of a tablet whilst playing slots — visual clarity and added space often make slot games come to life in a way that typical smartphones can’t match.

That being said, if portability is king for your mobile slots experience, smartphones are the obvious choice.

Real Money Slot Apps

The online casino landscape is becoming increasingly mobile-friendly. Every site you find on TopRatedCasinos has a mobile-optimised web page that adjusts to smaller, touch-centric interfaces, but the very best mobile experiences are found on native apps.

Not only are dedicated apps generally more responsive and specialised to smartphones and tablets, they also deliver push notifications to keep you abreast of the latest offers, and easy access to Google Pay and Apple Pay.

Here’s a brief selection of some of the finest real money slots apps in May 2022, available on both the Android and iPhone.

Casino Bonuses for Slots

Every top UK slots site will deliver welcome bonuses for new players and ongoing rewards for returning users, and they each come in a broad range of variants. From welcome bonuses to reload rewards, these are the bonuses you can expect to see at online slot sites in May 2022.

Free Spins

Free spins are a great way to boost your slots bankroll and enjoy extended playtime on some top titles. Many of the best slot sites offer free spins as part of the welcome bonus for new players, and they’re awarded when you make your first deposit. You could grab between 20 to 200 free spins, depending on where you play.

While some welcome packages offer a set number of spins, other bonuses increase the number of bonus spins in line with your deposit amount. Free spins typically come attached to winnings caps and wagering requirements, so be sure to read the terms and conditions before settling on an offer to make sure it’s right for you.

The actual value of free spins can also vary depending on which slots they’re eligible for, so pay attention to game restrictions too.

Matched Deposit Bonuses

Matched deposit bonuses see top online casinos reward new players with a percentage of their first deposit as bonus funds.

These bonuses offer players more flexibility than free spins deals as you can use these bonus funds to play games such as roulette and blackjack in addition to online slots.

The percentage match varies between casino sites, ranging from 50% to 200%, and will often be advertised as something like: ‘200% deposit match up to £100’.

These are the most lucrative bonuses out there, but they’re also apt to be tied to the steepest wagering requirements.

Take a look at both the individual site’s terms and conditions, as well as whether your initial deposit will be included in the wagering requirements as this can significantly increase the amount you need to wager in order to make withdrawals.

Nevertheless, with the opportunity to double your bankroll—or even triple or quadruple it—you can set yourself up with a huge glut of slots spins on top of your initial deposit.  

No Deposit Bonuses

Thanks to no deposit bonuses and free spins, you can play real money slots without even making a deposit. All you need to do is sign up and verify your account to grab your slot sign up offer.

These free spins bonuses are usually more modest than deposit deals, and usually max out at 10 or 20 no deposit free spins. but they still give you the chance to play slots online and win real money without having to dip into your own funds.

No deposit bonuses can generally be expected to come tethered to wagering requirements and winnings caps, although some sites, such as 32 Red, often waive such restrictions.

Check out an individual site’s terms and conditions to get a feel for how their no deposit bonuses will play out, and whether they’re well-suited to slot players.

Reload Bonuses

As the name suggests, reload bonuses are awarded when you make deposits beyond your initial one.

While you won’t be eligible for welcome bonuses after your first deposit, operators often reward returning players with smaller bankroll boosts and free spins — always handy when you’ve got a penchant for spinning the reels.

These bonuses may be linked with winnings caps, game limitations, and wagering requirements, so check the terms and conditions to avoid any unwelcome surprises.

Rebate Bonuses

Rebate bonuses are a welcome reward for anyone on a losing streak, which might especially be the case if you’re playing a slot with high volatility.

This bonus returns a percentage of your stake back to you either as you lose or when you’re on a run of losses, softening the blow somewhat.

Rebate bonuses are rarely, if ever, awarded as withdrawable funds, so bear in mind that this returned cash will usually have to be wagered again with the online casino.

VIP Bonuses

Whether your top slots site offers a tiered VIP system that sticks you into the mix from day one, or an exclusive invite-only system, VIP bonuses are a pleasant addition to any player’s bankroll.

Coming in the form of bonus funds, free spins, birthday rewards, dedicated account managers, enhanced odds on sportsbooks, real-world prizes, and more, VIP bonuses are a great sidebar to your slots experience.

Comp Points

Operating in a similar way to supermarket loyalty points, slots sites that offer comp points add them to your account as you make wagers.

The number of points you earn varies between sites, although you can typically expect a point for every £10 wagered. These points can then be traded in for prizes, either in the form of on-site rewards or physical prizes.

Comp points are a slow burn on the prizes front, particularly with the relatively low wagers played on slots, but they’re a pleasant treat when you’ve eventually racked up enough points to claim something.

Regular Promotions

Slots bonuses aren’t just for new players. The best UK slot sites have plenty of regular promotions to keep existing players coming back for more. Happy hour free spins, reload bonuses and VIP bonuses are just some of the rewards up for grabs at online slot sites.

Our bonus calculator tool makes it easy to find out the amount you’ll need to wager in order to meet your bonus’s wagering requirements. Enter the deposit value and percentage, the wagering requirements, the contribution percentage of your favourite game, and whether your casino includes your deposit in the calculation.

Bonus Terms and Conditions

Casino bonuses are much loved by slots fans, though they usually come with strings attached. You’ll need to compare terms and conditions to make sure the slots bonus suits how you intend to play.

Read on for a breakdown of the major considerations you ought to have in mind whilst selecting the best slots site for you.

Wagering Requirements on Free Spins

Unless you bag a no wagering free spins bonus, you’ll have to contend with wagering requirements. This means you need to wager any free spins winnings from the bonus a set number of times before you can make a real money withdrawal. When it comes to landing bonus wins, wagering requirements will have the biggest impact on what you can do with the funds.

Wagering requirements can vary massively between slot sites, though it’s usually no deposit bonuses that have the highest wagering requirements.

The average wagering requirement you can expect is 35x, although it’s not uncommon to see 50x wagering tied to the most lucrative bonuses.

Let’s say you’ve won £20 with your 50 free spins bonus set at 35x wagering. Your wagering requirements will be calculated like this:

  • £20 x 35 = £700

This means that you would need to wager £700 to be able to withdraw the £20 you won with your free spin bonus.

Wagering Requirements on Matched Deposit Bonuses

The amount you need to wager in order to make withdrawals against matched deposit-related funds can be calculated in one of two ways.

Let’s say you’ve claimed a 100% up to £100 welcome bonus with 35x wagering:

  • Deposit excluded: Bonus (£100) x wagering (35) = wagering requirement (£3,500)
  • Deposit included: [Deposit (£100) + bonus (£100)] x wagering (35) = £7,000

As you can see, the way your online casino calculates wagering requirements can have a huge impact on the amount you need to wager in order to unlock withdrawals, so be sure to check the terms and conditions to find out how an individual casino does things.

Wagering Contributions

Not all games are equal when it comes to completing wagering requirements. While bets on most slot games contribute 100% to wagering requirements, betting on table games can count for as little as 10% and are sometimes excluded altogether.

Games Restrictions

Free spins bonuses are often restricted to certain online slots. While some casinos reserve free spins for slots developed by a particular software house, others specify just a handful of titles.

You might find these deals are for a specific title, such as free spins for Starburst, or for the latest slot games.

Time Limits

You won’t have forever to use your slots bonus and complete your wagering requirements; there’s almost always an expiry date.

While some slot sites give you up to 30 days to use your bonus, others allow just a couple of days.

Max Win Limits

It’s unlikely that your free spins bonus is a free ticket to hitting the jackpot.

Even if you can play progressive jackpot slots with free spins and hit the jackpot, maximum win limits could mean you only see a fraction of those winnings as real cash.

Top Online Slots Software Developers

While some casinos specialise in games from just one software provider, others feature titles from a wide range of developers.

If you’re a fan of a particular brand, knowing which slot sites use its software can make finding your ideal casino that much easier.

While pretty much every casino software provider has slot games in its portfolio, this selection of industry leaders are sure to offer top online slots experiences.

NetEnt

NetEnt is one of the biggest names in casino software development, and it shows in their collection of top slot games.

Responsible for some of the most popular titles around, including Starburst, Gonzo’s Quest Megaways, and Jack and the Beanstalk, it’s easy to see how NetEnt earned its reputation. 

The NetEnt Rocks slot selection serves up plenty of music-themed games, such as Jimi Hendrix and Ozzy Osbourne slots.

NetEnt also offers some of the biggest progressive slots in the business — Mega Fortune once paid out a massive €17.86 million to a very lucky Swedish player.

The developer took home the gong for Innovation in Slot Provision at the EGR Awards 2016, and its Jumanji slot landed the title of Casino Product of the Year at GGA’s London 2019 awards, so you know that its games are among the best of the best.

NetEnt’s Starburst

Microgaming

With famous titles like Hot Ink, Thunderstruck and Jurassic Park in its portfolio, Microgaming definitely knows its stuff when it comes to online slot games.

This developer also proudly holds the world record of largest ever slot payout, when one player bagged a whopping €19.4 million progressive jackpot on Mega Moolah.

Microgaming won the EGR Innovation in Slot Provision award in 2011, and since then has taken home prestigious awards, such as iGaming Software Supplier of the Year at the 2018 International Gaming Awards.

Microgaming’s Jurassic World

Playtech

This software giant won EGR Slots Provider of the Year in 2013 and its quality software has continued to take home prizes ever since.

Playtech made its name with a top collection of online slots including the likes of White King and Jackpot Giant, as well as iconic film and comic-themed titles, such as Gladiator and Superman.

The Age of the Gods series is Playtech’s best-known game collection,  though Ugga Bugga and Goblin’s Cave feature some of the highest RTPs on the market—99.07% and 99.32% respectively.

Playtech’s Age of the Gods: Prince of Olympus

Play’n GO

Founded in 1997, Sweden-based Play’n GO is famous for its world-class collection of slot games. This includes the legendary Rich and Cat Wilde series, which follows two Indiana Jones-esque characters across the globe in search for lost treasures. Fire Joker, Reactoonz, and Moon Princess are some of this developer’s other popular titles. 

Following the emergence of mobile gambling, Play’n GO pivoted its offering to the mobile market, and is now regarded as one of the world’s best developers of mobile slots. As such, it’s picked up multiple prizes in both Slot Provider and Mobile Product categories at various industry award ceremonies over the years.

Play’n GO’s Rich Wilde and the Book of Dead

Yggdrasil

Yggdrasil is comfortably the youngest developer on this list, but its games feature prominently at the UK’s best slot sites. Founded in 2013, Yggdrasil’s slots are powerful, colourful, and uncompromisingly alternative — titles such as Vikings Go Berzerk, Valley of the Gods, and Orient Express are all testament to that. 

Yggdrasil takes its name from the ancient Norse mythological concept of the same name, which states that all life is born from one sacred tree. As a result, many of Yggdrasil’s slots are imbued with a unique aesthetic, which has seen this developer crowned as the industry’s most innovative at several major award ceremonies.

Pragmatic Play

With offices in Malta, Gibraltar, and the Isle of Man, Pragmatic Play is known for its high calibre when it comes to online slots. Although the company was only founded in 2015 — making it one of the younger developers on our list — it’s already expanded its catalogue to over 200 titles, among which are fan favourite slots such as Gates of Olympus, Chilli Heat, and Wolf Gold. 

But it’s not just the players who recognise Pragmatic’s focus on quality: the developer picked up the honour of Software Rising Star at the 2017 EGR B2B Awards just two years after its founding, followed by Innovation in Slot Provision a year later. Once you’ve tried a Pragmatic Play slot, these industry accolades will come as no surprise — load up one of its games and you’ll be met with pristine, vibrant graphics, as well as immersive sound and a host of bonus features to boot. All of Pragmatic’s games are built with mobile devices in mind too, utilising HTML5 technology so you can play popular titles like Wild Wild Riches, Fire Strike 2, and Queen of Atlantis on the go. 

Chilli Heat from Pragmatic Play, a five-reel, three-row slot with 25 paylines and an RTP of 96.5%

IGT

There’s no doubt that IGT is one of the stalwarts of video slots development — the company dates back to the 1980s, with a seasoned background in supplying physical slot cabinets to brick-and-mortar casinos around the world. Come the 90s, IGT decided to apply its expertise to the iGaming space to develop online slots and other virtual casino games. The company is somewhat of a behemoth today, with a presence in over 100 countries including its headquarters in London, and employing over 10,000 people.

So, how about IGT’s games? One of the developer’s most popular slots is Cleopatra, first released in 2012. The game has had numerous revamps throughout its history, including the Diamond Spins, PLUS, and MegaJackpots versions of the game — each one throws an innovative IGT game mechanic into the mix. Other popular titles include Great Bear, Da Vinci Diamonds, Cats, and Siberian Storm, all of which showcase IGT’s top-notch gameplay and HD graphics.

The MegaJackpots version of Cleopatra, part of IGT’s progressive jackpot network which seeds at £500,000.

Nolimit City

The slightly fresher-faced Nolimit City was established in Stockholm, Sweden in 2013, but has certainly made waves within the industry in the decade since. Focusing solely on slots, the developer has continued to push the edge of the genre by incorporating exciting new mechanics and unique — albeit sometimes a little extreme — themes in its titles. 

One of the standout elements of Nolimit City’s portfolio is the xFeatures gameplay, a set of mechanics which spice up the usual reel-spinning action, including:

  • xNudge – a stacked wild that nudges in to cover the entire reel, with a multiplier added for every position it nudges;
  • xWays – Nolimit’s take on expanding reels, including the Infectious xWays variant that spreads across reels;
  • xBomb – an exploding symbol that removes all but scatters and wilds from the reels, replacing them with new symbols while adding an extra row to the reels and a multiplier to the payout;
  • xPay$ – when adjacent symbols land on the first three reels, winners are collected at the bottom of the reels while non-winning symbols are replaced with new ones.
  • xSplit – a bit like xWays, this feature splits symbol positions in two to help you complete paylines

Nolimit City has a strong library of games, all of which feature incredibly sharp and detailed graphics in cartoony and hand-drawn styles. Another defining characteristic of this developer’s slots is the dark humour running throughout, which really adds another level of entertainment not found from other software houses. 

We’ll warn you now — many of its titles aren’t for the faint of heart, with games like Deadwood RIP, San Quentin, and Mental bringing some truly gruesome themes to the reels. Fancy something a bit more light-hearted? Try the rap-inspired East Coast vs West Coast or the rather crude Punk Toilet.

Deadwood xNudge, the first Nolimit City game to incorporate the xNudge wild symbol feature.

Responsible Gambling with Online Slots

Wondering how to win at slots? While there are no hard and fast ways to guarantee success on the slots, we have a few online slots tips to bear in mind as you select your games.

  • Remember to play for fun

While you’ll struggle to find anyone that doesn’t love hitting a jackpot, the reality of slots is that you’ll be losing a lot more often than you win.

If you find that you’re hitting the spin button out of frustration at a losing streak rather than for the thrill of watching the reels slide into position, your best bet is to walk away and come back later. As they say: when the fun stops, stop.

  • Choose slots that work to your budget

Payouts scale with denominations wagered. Ergo, if you’re betting on a 10p slot, you can expect a winning payline to cough up less than a 50p slot. That being said, your slots experience will be short-lived if you only have the budget for 20p wagers and you’re wagering 50p with each spin.

Consider how long you want to play for and how much that duration might cost if you don’t hit any winning paylines, and you’ll be able to make a sound judgement on how much to wager with each spin.

Once you’re armed with that information, you’ll be well positioned to pick an appropriate slot for your budget.

  • Be sure to wager the necessary amount for the jackpot

If you’re playing a progressive jackpot, a percentage of each wager goes towards the jackpot and racks up tantalisingly throughout your session.

Most slots of this breed require you to wager a certain amount with each spin in order to qualify for the jackpot, so be sure to pay attention to the minimum required if you’re playing a jackpot slot.

  • Pick slots from top developers

Keep an eye on who developed the games you’re considering. Generally speaking, the best-known names in the industry are that way for a reason: they make the best games.

Pay attention to the return-to-player ratio as well, and ensure you’re playing on games with an RTP of at least 95%. Volatility plays a part as well, with high volatility slots paying out per win but tending to deliver more protracted dry spells.

  • Pick a bonus that’s slots-focused

When you’re selecting a new slots site to sign up to, you ought to consider going for bonuses that lend themselves well to slots.

Free spins are a no-brainer, but be sure to check whether they have a winnings cap or wagering requirements attached to avoid having the rug swept out from under you when you land a win.

Wager-free bonuses are the holy grail of bonuses generally, but they’re a particularly handy way to hit the slots without having to wager your own cash.

  • Set time and wager limits for yourself

It’s no secret that slots are designed to massage your dopamine receptors and keep you fixed to the spin button, so always try and exercise your best judgement when playing the reels.

Set a time limit so you don’t play for longer than you want to and be sure to set a hard limit for the amount you want to spend during your session.

Spin the Reels at a Top UK Online Slots Site

Frequently Asked Questions

  • Yes. Every slot site on listed at TopRatedCasinos holds a UKGC licence. The UKGC monitors its licensees and audits their games to check for fairness and the accuracy of advertised RTP. In addition this, UK licensed casinos are held to high standards when it comes to protecting vulnerable players and player information. If you’re ever in doubt about a site’s licence status, check the UKGC’s public register.

  • No. Winning at slots comes down entirely to chance and, unlike poker or blackjack, it doesn’t require any skill. This means there’s nothing you can do to increase your chances of landing a winning symbol combination.

  • While some slot games pay out as much as £400,000, the amount you can win depends on how much you bet, and whether you land lucky bonus symbols to boost your winnings. If you’re playing progressive jackpot slots, the amount you win will depend on the size of the jackpot- these can reach well into the millions!

  • No. It’s unlikely that you’ll find no deposit free spins with no wagering requirements at UK slot sites – especially as a welcome bonus. Casinos might offer similar deals as part of a happy hour promotion or loyalty reward program, but you’ll almost always need to have made a deposit in the past.

  • This depends on the number of reels, the number of symbols on the reels and the number of paylines you bet on. The more simple the slot game, the better your odds for landing a winning combination. For example, if you bet on a 3-reel slot game with seven symbols on each reel, the chances of you landing 3 matching symbols is 1 in 343. However, if you’re playing a 5-reel slot with 10 symbols on each, you’re in with 1 in 100,000 chance of winning.

  • Yes. While there’s a handful of online casinos that are solely dedicated to slot games, most UK slot sites also offer a selection of other games. While roulette, blackjack and baccarat are the most common selection, some also offer video poker and live dealer casino games.

  • Slot developers aren’t currently required to state their slot titles’ volatility, or variance. While some developers include this information alongside the slot’s RTP, many slots have had their volatilities worked out by online communities comparing their experiences. If the slot volatility isn’t stated at the online casino in question, a quick search on Google can give you an idea of what to expect.

  • Developers and online casinos are required by licensing conditions to state every slot game’s RTP. Generally, this information is included alongside the paytable, which can be accessed by clicking the small ‘i’ icon on the slot’s display. If you can’t find the RTP, the online casino’s customer support team will be happy to help.

  • Yes. However, while you can win real money with a casino bonus, you’ll need to be mindful of the terms and conditions. Most bonuses are tied to wagering requirements which lock your bonus-related winnings away until you’ve wagered the bonus value a certain number of times over. For free spins, the wagering requirements will be calculated using the value of your free spins winnings. Details of this, and other restrictions, will be listed in the bonus’s terms and conditions, so be sure to read the fine print.

  • If your online slot site offers fast withdrawals, you’ll usually need to use an e-wallet such as PayPal, Skrill, or Neteller to take advantage of the service. Payout speeds for each accepted payment method are typically listed in the site’s terms of service but, failing that, the customer support team will be happy to give you the information.

  • Real money slots are a perfectly legal way to gamble, and the games available will be held to strict levels of fairness provided the online casino in question is licensed by the UK Gambling Commission (UKGC).

    Never play at an online casino that doesn’t have a UKGC licence, as unlicensed sites have no guarantees or protections in place regarding fair play, ethical behaviours and transaction security.

    One of the licensing obligations for operators is to conduct regular audits of the random number generator (RNG) tech powering their slots’ randomness, so you can be sure that licensed sites are offering slots that aren’t rigged.

Blacklisted Casinos

If you’re looking for a top UK slots site, take heed of the blacklisted operators below. We’ve highlighted these names because they’ve fallen short when it comes to the treatment of their players.

Sites without a proper licence will be automatically blacklisted as these sites are likely to act against players’ interests.

At TopRatedCasinos.co.uk, we only ever recommend sites licensed by the relevant authorities — in the UK, that’s the UK Gambling Commission (UKGC).

Some of the other reasons we’ll blacklist a casino include difficulty withdrawing funds, rigged or unfair games, and unresponsive customer support.

Operators that engage in practices such as spamming or false advertising will also quickly find themselves with a black mark against their name.

Here at TopRatedCasinos.co.uk, we want you to have a great experience every time — we’d urge you to avoid playing at the names below for that reason.
