How to play at online slot sites

  1. Compare slots casinos

    Use our 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 signup 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!

Why play online slots?

Here’s why you might choose online slots over other casino games

Simple

Slots are about as straightforward as it gets when it comes to online casino games. There’s no skill or strategy involved- you just hit spin and hope your luck’s in. That’s not to say the simplicity of slots makes them any less exciting; entertaining themes, lively animations and thrilling bonuses mean there’s plenty of fun to be had.

Suits all budgets

Whether you’re a beginner, a casual player or a casino veteran, there’s a slot game for every kind of bankroll. From penny slots to high roller progressive jackpots and plenty of betting opportunities in between, the power is in your hands. You can even play slots for free with free demo games!

Variety

Sure, classic table games like roulette and blackjack have their fair share of variations, but nothing rivals slots when it comes to the sheer range of slot games on offer.  Pretty much every software developer makes slot games, and many top slot sites boast over 500 exciting titles, so the possibilities are endless.

How to play slots 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 potential payouts, 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 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 slots

While you don’t actually have to deposit to play at UK slot sites, 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 a spin, while 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 are real money slot games for high rollers too.

Free slot games

You don’t need to deposit to play online slots, thanks to free slot games. These are available at pretty much all UK slots sites and, while you can’t win real money on free slot games, they’re great if you just want to play slots for fun. They’re also ideal for beginners easing their way onto the slots scene, and give you a chance to familiarise yourself with pay tables and bonus features before trying out real money slots.

New slot sites

With brand new slot game releases every month, you need never tire of playing the same titles. Bigger brand deals, innovative features and better graphics are just a handful of features you can expect from the newest slot releases- each bringing something a little different to keep players on their toes.

However, it’s not just new slot games that you should look out for- new slot sites can also get pretty exciting. While the newest slot sites tend to feature the latest games, you can also expect the likes of fresh designs, exciting bonus rewards and leaderboards. Luckily for you, we’ve picked out the best newest slot sites to help you make your pick.

Top online slots software providers

Whereas 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, these three dominate the industry:

NetEnt

NetEnt is one of the biggest names in casino software development, and it shows by their collection of top slot games. Responsible for some of the most popular titles around, including Starburst, Gonzo’s Quest, and Jack and the Beanstalk, it’s easy to see how NetEnt earned its reputation. Its 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! NetEnt 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.

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 £13 million progressive jackpot on Mega Moolah. Microgaming won the EGR Innovation in Slot Provision in 2011, and since then has taken home prestigious awards, such as iGaming Software Supplier at the 2018 International Gaming Awards.

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.

Mobile slots

Slots makes the perfect mobile casino game and, 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

Whereas online slots used to be made using Flash, now the top developers create their games using HTML5. This means 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.

Casino bonuses for slots

There’s no shortage of slots bonuses at the UK’s top slot sites, and these rewards come in different shapes and sizes. From welcome bonuses to reload rewards, these are the bonuses you can expect to see at online slot sites.

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, rewarded when you make your first deposit. You could grab between 20 to 200 free spins, depending on where you play. Whereas some welcome packages offer a set number of spins, other bonuses increase the number of bonus spins in line with your deposit amount.

No deposit free spins

Thanks to no deposit 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 this reward. 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.

Matched deposit bonus

Matched deposit bonuses see 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 ‘200% deposit match up to £100’.

Regular promotions

Slots bonuses aren’t just for new players. The best UK slot sites have plenty of regularly 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.

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.

Wagering requirements

Unless you bag a no wagering free spins bonus,  you’ll have to contend with wagering requirements. This means you need to wager your free spins winnings a set number of times before you can make a real money withdrawal.  Wagering requirements can vary massively between slot sites, though it’s usually no deposit bonuses that have the highest wagering requirements.

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 tables games can count 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.

In-game slots bonuses

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 mini-games 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.

Understanding RTP of online slots

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 in a short period of play.

You can find a slot’s RTP in the paytable. Just click ‘?’

The UKGC monitors both online casinos and software developers to ensure that the RTP for each game is accurate and up to date.

Slot variance

High RTP doesn’t necessarily mean you have a better chance of winning, or that a slot is more profitable. Slot variance 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.

How to choose the best online slot site for you

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

Games library

No one wants to sign up to an online casino only to see that it’s missing their favourite title, so check out what’s on offer before you sign up. Most slot sites let you browse the games library 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.

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,  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.

Banking options

The best UK slot sites offer a range of banking options these days, from bank cards to e-wallets and everything 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, we’ve made it easy to see what banking options are on offer at each site.

Mobile compatibility

If you want to play slots on your mobile, 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?

Withdrawal terms

Terms don’t just apply to bonuses. You need to check how easily you can access any winnings. Compare withdrawal banking options, processing times and minimum withdrawal limits when you’re picking your favourite slot site.

Customer support

Chances are you’ll probably never need to use customer service, but it’s good to know it’s there just in case. 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.

Frequently asked questions

  • Can I trust these online slot sites?

    Yes. Every slot site on our list 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.

  • Is there a strategy to help me win at slots?

    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.

  • How much can I win playing online slots?

    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!

  • Is it possible to find a no wagering no deposit free spins bonus?

    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.

  • What are the odds of winning online slots?

    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.

  • Can I play other casino games at top slot sites?

    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.
