Our Picks for Best Online Slot Sites
Before we get on to anything else, we’re diving straight in with our top choices for the best UK online slot sites. Our casino slots experts at Gambling.com will always give you the real deal, with upsides and downsides for each casino we recommend so you can trust our reviews.
Best First Deposit Slot Site: Dream Vegas Casino
- Best Features: Apart from a vast selection of slot games from top-tier developers, Dream Vegas Casino offers a great first deposit bonus of up to £300 plus 150 free spins to enhance your gaming experience.
- Biggest Negatives: With only bonus funds contributing to the 35x wagering requirement, it can be challenging to withdraw your winnings quickly.
- Alternative: LeoVegas Casino
- Our View: Despite the steep wagering requirements, Dream Vegas Casino is an excellent choice if you're looking for variety and a generous start to your online slots UK journey.
Best Free Spins Slot Site: Kwiff Casino
- Best Features: Kwiff Casino’s welcome offer is all about free spins, giving you up to 200 free spins over the first five days from your first deposit. This gives you numerous opportunities to try out their diverse slot games without risking your funds.
- Biggest Negatives: On the flip side, you might find that these free spins are often restricted to specific slot games, limiting your exploration of the wider slot game library.
- Alternative: Fun Casino
- Our View: Although the free spins are confined to certain games, Kwiff Casino offers an impressive platform for slot lovers with their significant free spins offer. It's the best online slots site if you enjoy spinning the reels without risking much of your own money.
Best Progressive Jackpots Slot Site: Spin&Win Casino
- Best Features: Spin&Win Casino has close to 200 progressive jackpot slots amongst an offering of more than 18,000 jackpot slots - an exceptional offering of progressive jackpots, providing you with a chance to win substantial sums of money across a variety of thrilling slot games.
- Biggest Negatives: Although not particular to Spin&Win Casino, the chances of winning these huge jackpots are generally low and the high volatility of such games may not suit every player's preferences.
- Alternative: Playgrand Casino
- Our View: Even with the risks associated with high volatility games, Spin&Win Casino stands out for its wide range of progressive jackpot slots. If you're chasing the excitement of a big win, this top slots casino could be your go-to destination.
Best Megaways Slot Site: Rainbow Riches Casino
- Best Features: Rainbow Riches offers the possibility of gold at the end of the slots rainbow, with thousands of ways to win on each spin. You can even try many of the slots on offer in demo mode before committing any money towards them.
- Biggest Negatives: You might find the site somewhat limited if you're a bonus hunter – it doesn’t exactly have the widest range of promotions.
- Alternative: JackpotJoy Casino
- Our View: Not only does Rainbow Riches win the best Megaways slot site award, but it is also one of the most comprehensive casino sites you will encounter thanks to the fact it marries casino with bingo and poker. If you’re out for a one-stop shop with an emphasis on Megaways, this casino is a top-tier choice.
Best Slot Site for Themed Slots: PartyCasino
- Best Features: At PartyCasino, you’ll find a comprehensive array of branded slots based on popular TV shows, movies, and cultural phenomena, giving you a chance to engage with your favourite themes in an interactive gaming environment.
- Biggest Negatives: The slot site’s primary emphasis is on feature-rich branded slots, so you might feel a bit let down if you’re interested in more traditional or simpler slot formats.
- Alternative: HeySpin Casino
- Our View: While PartyCasino may not cater as much to lovers of classic slots, its focus on themed slots makes it a highly engaging platform for UK slots players seeking immersive, pop culture-themed gaming experiences. If you love the cross-over between entertainment and gambling, this is a top pick.
Best Online Slots UK Sites
Online casino slots are very popular in the UK and there seems to be no slowing down on the horizon. Because of this, more and more casino sites are offering slot games online, and it can seem quite daunting to separate the best from the worst.
However, we’ve done the work for you. The best casino slots UK sites will all hold a licence from the UK Gambling Commission (UKGC) or a respective jurisdiction. They will offer attractive online slot offers, many including a free spins bonus, and their games will all be fully optimised for mobile play. Apart from that, the best slot sites that we recommend will have a huge selection of banking options, with fast withdrawal times for you to get your winnings.
How to Play Online Slot Games
When you set the reels of a slot game in motion, your aim is to land winning combinations of symbols. If the symbols line up correctly, you'll earn cash prizes or other forms of rewards. Certain UK slots also feature extras that boost your chances of winning, such as bonus rounds, free spins, and wild symbols, which stand in for other symbols to create winning combinations.
Online slot games provide a range of betting options, enabling you to select the value of the coins and determine the bet amount per line and the number of paylines. This allows you to tailor your bets to suit your budget and personal preferences.
To ascertain the amount you wager for each spin, first choose the value of the coins you wish to bet with. Many slot games allow you to adjust the bet level, which determines the number of coins per payline. For instance, if the coin value is £0.10 and you choose bet level 10, your total bet per payline will be £1 (10 times the initial coin value).
Finally, you can decide how many paylines you wish to activate. Paylines are the symbol combinations that can result in a win and can appear horizontally, vertically, diagonally, or in irregular patterns. The paytable for each multiline slot game will be shown in the paytable diagrams.
Our advice is to play the maximum number of paylines possible - if you're working with a limited budget, reduce the bet amount rather than the number of paylines you wish to play. Use the 'max bet' button if you wish to select all the paylines at once.
Slots UK Game Variety
Online slots come in a multitude of styles and themes, catering to a broad range of preferences. For an optimal playing experience, it's beneficial to be familiar with each type's unique attributes. Below, we provide concise descriptions of the most popular slot categories:
1. Classic Slot Games
Often referred to as 'fruit machines', these digital versions of old-school slot machines harken back to the vintage casino era. With symbols like cherries, bars, and sevens, they're easy to play and typically feature three reels. While they may lack modern bonus rounds, their nostalgic appeal is undeniable.
Our top picks: Mega Joker and Break da Bank.
2. Video Slot Games
The modern version of slots, video slots blend advanced graphics and sound with engaging gameplay elements. They come with a rich variety of themes, bonus features, and often more than five reels. Standout games in this category include Gonzo's Quest, Starburst, and Immortal Romance.
Our top picks: Jammin' Jars, Fat Rabbit, The Dog House, and Reactoonz.
3. Branded Slot Games
These slot games are the result of collaborations between slot developers and major entertainment franchises. They bring iconic movies, TV series, or musicians to the slot world, offering fans a unique spin on familiar themes.
Our top picks: The Walking Dead, Game of Thrones, and Rick and Morty slots.
4. Megaways Slot Games
Slot games using the Megaways mechanics can offer up to 117,649 ways to win. The dynamic nature of symbol arrangements on reels keeps players on their toes, promising an unpredictable and thrilling game session.
Our top picks: Bonanza Megaways, Gonzo’s Quest Megaways, and Monopoly Megaways.
Progressive Jackpot Slots
The dream of landing a life-changing fortune is on offer with progressive jackpot slots, with each bet contributing a small portion to a continually growing jackpot.
These progressive online slot pools keep on increasing until one player strikes it rich.
The biggest are the WowPot and Mega Moolah series of jackpot slots, but below we list all of the big online slots jackpots currently up for grabs, along with the best UK slot sites where you can try your luck for each.
Online Slot Progressive Jackpot Amounts (November 2023)
Microgaming launched the original safari-themed Mega Moolah progressive jackpot slot back in 2006 to much acclaim.
Since then, the Mega Moolah series has been expanded to include a variety of titles, such as Fortunium Gold, Mega Moolah Goddess and Absolootly Mad - the latter of which holds the record of the largest online slots jackpot ever won (£16.9 million in April 2021).
That monster win came just two weeks after a record WowPot jackpot of £15.2 million, won by a UK 32Red player on the Book of Atem game.
But hold the front page as the WowPot jackpot pool is currently over £40 million and is just waiting to be won again. Other popular games in the WowPot series include Sisters of Oz, Wolf Blaze and Sherlock & Moriarty.
Whilst the aforementioned slots contribute to shared jackpot pools, both Jackpot Giant and Mega Fortune are stand-alone games, each boasting its own progressive jackpot.
Online Slots Real Money
While playing online slots is fun on its own, the thrill is always higher when there’s a chance to win some real money. There are thousands upon thousands of real money slots out there, but not all of them are as lucrative.
Our team at Gambling.com has taken the initiative to find the most paying slots, and from our testing, we’ve come up with a mix of what we think are some of the best games in the business right now.
Here’s our list of the top 10 online slots real money UK. The games below aren’t just all video slots either, with a nice mix to get your juices flowing.
- Starburst – You’re going to need to get to know Starburst well if you start to claim any bonus spins from your online casino. The majority of them are targeted towards this game and as a result, is a great beginner slot with a friendly 96.08% RTP.
- Book of Dead – This slot is part of the popular Riche Wilde series from Play’n GO. Launched over 5 years ago, Book of Dead remains one of the best games to play with all the features and free spins on offer. The RTP is a decent 96.21% and you can win up to half a million pounds if all works in your favour.
- Bonanza – Another hit from Big Time Gaming, Bonanza offers loads of exciting gameplay with an unusual grid layout, a mini bonus game, and unlimited multiplier wins and other features. It is highly volatile and has an RTP of 96%, but if you’re looking for a thrilling, high-risk game, this is the one for you.
- Wolf Gold – A visually stunning game, Wolf Gold also comes with multiple bonus features and a jackpot that offers Mini, Major, or Mega prizes. Every player is in with the chance of winning 250,000 coins, and it is a medium volatility slot, making it perfect for players who have never played a jackpot slot before.
- Gonzo’s Quest – This is one of the most iconic video slots in the industry. It started life as a NetEnt catalogue game but is now arguably a brand of its own. A slot packed with features, slot bonus rounds, free spins, and a great storyline. What more could you want?
- Big Bass Bonanza – One of the most popular slots ever, let alone by Pragmatic Play, Big Bass Bonanza offers a fun and simple base game, and an action-loaded free spins round. The RTP is a pleasing 96.71%, and you can get up to 2,100x your stake.
- Legacy of Dead – Legacy of Dead is part of an ancient Egyptian-themed slot series by Play’n GO. The graphics are beautiful, you can get up to 10 free spins, and there is an array of features you can trigger. It is a highly-volatile game suitable for those who dare, and comes with an optional gamble feature that could see you doubling or quadrupling your wins.
- Primate King – This is a game with an exciting theme and an equally exciting protagonist. The primate king (the gorilla) has the ability to smash away lower paying symbols in the Primate Smash bonus, allowing for even bigger wins. The RTP is a bit on the lower side at 95.66%, but that’s offset by the valuable wild upgrade feature.
- Gonzo’s Quest Megaways – This slot takes a classic, Gonzo’s Quest, and upgrades it with the Megaways mechanics. This means that you get all the fun features from the original slot and a mega number of ways to win with the Megaways software. The RTP is 94.66% but you can win great prizes in both the base game and the bonus rounds.
- Sweet Bonanza – Sweet Bonanza has a good RTP of 96.48%, and gives players the chance to win over £2,000,000. It is definitely one of the most modern games with no traditional paylines and the ability to customise the volatility level in the bonus games. This makes it suitable to all players regardless of their bankroll, and with its colourful graphics, it’s hard not to give in to the temptation!
Online Slot Sites Software
We’ve spoken a couple of times in this article about game providers and we wanted to add a little more information about that. The first thing to note is that almost all casinos get their games from 3rd party casino software providers. These companies create the games and then sell off the rights to the casinos.
There are a couple of reasons why casinos do this. The first is that it saves investing in the huge costs that come with game development and the research and development that comes with them.
The second is that it’s one less job to look after. They know they can sign an agreement, often with several developers, and then the games are ready to go within their casino.
This is now a highly competitive marketplace and there is a huge emphasis on improving existing games and coming up with new, exciting titles. It’s big money for the developers, but the rewards are there as well, should they succeed.
Below we’ve listed several of the leading software developers for online slots UK.
NetEnt
NetEnt is a Swedish based company that has had to work hard to get to the top of the tree. It’s been the game innovation that’s allowed it to succeed, and which has led to a range of slots that are now iconic.
Two standout games from its ever-increasing back catalogue are that of Gonzo’s Quest and Starburst. The former now figureheads the NetEnt brand, whilst Starburst is recognised as one of the go-to online slots for most bonus spins offers.
Playtech
Another of the big hitters is Playtech. Playtech was one of the original casino game developers back in 1999 and has been in since the ground up.
Playtech is one of few providers able to power whole casinos on its own, highlighting the range of games that it offers. There are a plethora of standout titles, including a huge range of branded slots. Some of these include Justice League, The Dark Knight, and Frankie Dettori’s Magic Seven.
Yggdrasil Gaming
Yggdrasil Gaming is one of the many success stories that you hear about within the game software sector. The company was formed back in 2013 but has quickly cemented itself as one of the best in the business.
Yggdrasil doesn’t get the accolades that the bigger brands do, but the quality of games, particularly slots, is second to none. Games such as Vikings Go Wild, Vikings Go Berserk, and Blood Moon Wilds are three of its marquee titles.
Play’n GO
Play’n GO is another Scandinavian brand doing well in the online slots section. Formed in 2007, it has now a wealth of games at its disposal and has been able to put a precedence on making sure that RTP rates are high as they can be.
Standout games from the brand include the likes of Troll Hunters 2, Rich Wilde and the Shield of Athena, and Rally 4 Riches. What’s noticeable about each of these games is that they follow an exciting story as you play, unlocking a max bonus round and features that many of Play’n GO’s competitors don’t have.
IGT
IGT has been able to specialise in themed games, as well as branded slots over the last decade or so. The company splits its work between online and live casinos, creating a huge number of slot machines that you see all over the world in brick-and-mortar casinos.
Online, it has got a massive range of casino slots to choose from. What’s epic about IGT is that any games that are dated or are no longer up to scratch either get refurbished or ditched. This is rare, but from a user experience perspective, something that is highly welcomed.
Standout games here include the likes of Family Guy, Ghostbuster, Baywatch, Cleopatra, and Wheel of Fortune.
Novomatic
Novomatic may not be the first brand that you think of when it comes to software developers, but it is the oldest in this list, dating back to 1980. The company not only has a great range of online slots but also over 2,000 land-based casinos that are hosting its games.
Games wise, the Book of Ra is what it is best known for, but other games include Lord of the Ocean, Dolphin’s Perl, and Sizzling Hot, each adding to a strong package that’s on offer from Novomatic.
Online Slots UK Bonuses and Free Spins
Online casinos often entice players with welcome offers, typically in the form of a welcome bonus or bonus spins. The specific offer varies based on factors like your initial deposit and wagering requirements.
It's essential to understand that welcome bonuses are not just free money; they come with wagering requirements. To withdraw bonus funds, you must wager them a certain number of times, usually between 20x and 50x the bonus amount. For instance, with a £100 bonus and a 20x wagering requirement, you'd need to place £2000 in bets (20 x £100) before you can withdraw.
Wagering also has game limitations, meaning not all bets contribute equally. Online slots typically have a 100% contribution rate, but other games may vary.
Consider the casino bonus expiry date, eligible games, whether the wagering applies to the bonus alone or both bonus and deposit, and which deposit methods qualify for the offer.
Bonus spins are more straightforward; you receive spins for specific slots, and you can usually keep your winnings. Watch for limitations on stake per spin, the number of spins, and eligible games.
Best No Deposit UK Slots Sites
The no deposit bonus offer is so good, it had to have a section of its own. A no deposit bonus means that new players are rewarded with extra funds simply for signing up, and just like the name suggests, the player is not required to deposit a wager! The only thing you need to do is find an online slot site that offers a no deposit bonus, sign up and verify your account, and the casino will credit your balance with the bonus money. Just like that!
Naturally, since this kind of offer is so lucrative, it can be very rare to come by. However, we won’t have you scouring the internet to try and find one as we’ve got the best one right here. 888 Casino will give you 88 Free Spins for signing up, without you needing to deposit any of your money. Better yet, the winnings are paid in cash!
Highest RTP Slots 2023
Here are the top 15 best paying slot games in the UK ranked by their advertised RTP (Return to Player) percentage.
Most online slots in the UK typically have RTPs ranging from 92% to 96%, but all of these best paying slots feature an RTP of 97% or higher:
The RTP percentage is a factor to consider when selecting which online slots to play. This provides an estimate of the expected returns over an extended period of time.
Theoretically, for every £1 staked on an online slot game with a 98% RTP, 98p is returned.
The RTP % of a slot machine is not guaranteed, it's a calculated long-term average of the amount paid out divided by the amount staked on that game. It does not indicate the outcome of any individual game session.
But by choosing the best paying online slots with higher RTPs, you are likely to get more value for your money over the long run and maximise your bankroll.
However, some players prefer online slots with lower RTPs and higher 'max wins' or the allure of massive progressive jackpots.
For example, despite Mega Moolah's RTP of 88.12%, it has awarded several huge jackpots to UK players, like the £13.2 million won by Jonathan Heywood at Betway in 2015.
Online Slots Tournaments UK (November 2023)
Slots tournaments add a competitive edge to spinning the reels, with additional rewards above and beyond regular slots gameplay.
In these scheduled tournaments, players compete against each other to win cash prizes or other rewards.
While each slots tournament has its own rules, the goal is always to accumulate points to rise up the leaderboard.
Here we have listed the tournaments currently available at UK slot sites:
The most popular online slots tournaments in the UK are Drops & Wins, available exclusively on Pragmatic Play slots games.
With a monthly prize pool of £2 million, this promotion offers prize-paying positions on weekly tournament leaderboards, plus random daily prize drops:
£255,000 for weekly leaderboards x 4 weeks = £1,020,000
£35,000 in daily prize drops x 7 days a week x 4 weeks = £980,000
We especially like the random daily prize drops which give everyone who plays a chance to win, not just those who make it onto the weekly leaderboard.
Best Slot Games – What are They?
Of course, what makes the best slot games is not just the RTP as other factors need to be taken into consideration. One of these is finding games developed by the top software providers. The best online casinos in the UK will carry games from multiple providers and might also have exclusive casino slots which you will not find at any other casino. The best slot games will also provide players with a thrilling gaming experience, keeping the player involved. This comes in the form of stunning visuals, fun themes, spins, bonus rounds, and other exciting features.

Tips for Playing Online Slots UK
For beginners and seasoned players alike, playing online slots can be an exciting and potentially lucrative pastime. To maximize your enjoyment and improve your chances of winning, here are some key strategies and tips to consider:
1. Understand the basics: It's crucial to grasp the basics before you start playing. Understand what paylines, reels, and symbols mean. Learn about different types of slots – classic, video, progressive, and more. Also, get familiar with terms like Return to Player (RTP) and Volatility. RTP refers to the percentage of all wagered money a slot machine will pay back to players over time, and Volatility relates to the risk level associated with a particular slot game.
2. Choose the Right Slot: With the vast array of slots UK available, selecting the right one can seem daunting. The key is to find a slot that fits your preferences and playing style. Consider factors like the theme, RTP, Volatility, and the number of paylines when making your choice.
3. Utilize Free Plays and Bonuses: Most online slots UK sites offer free plays, bonuses, and promotions. These can be a great way to try out a game before risking real money, or to extend your playtime. Always read the terms and conditions associated with any bonus, as there can be wagering requirements or other restrictions.
4. Manage Your Bankroll: Responsible gaming involves setting a budget for your online slot play and sticking to it. Never wager more than you can afford to lose, and consider setting a time limit for your play sessions to prevent getting carried away.
5. Keep It Fun: The most important tip of all is to remember that online slots should be a fun experience. It's thrilling to win, but remember, the primary goal of playing slots is entertainment. Keeping this perspective can help make your online gaming experience more enjoyable.
UK Paypal Slot Sites
Independent slot sites have come a long way over the last decade or so, and one of the biggest innovations has been the number of ways that you can get your money in, and most importantly, out of the casino.
With PayPal, gone are the days of having to wait sometimes even more than a week to be able to access your winnings. UK slot sites that take PayPal are becoming increasingly popular since Paypal is usually the fastest way to get your money out. Withdrawals can be back into your account as quickly as within 24 hours, and most of the time, you can get your cash immediately if you need to. Another benefit to playing at a PayPal casino is that it is secure and your payments will remain semi-anonymous since you won’t have to give the casino your banking details. Having said that, you will still need to verify your PayPal account.
There are a series of other payment methods that you can access as well. These include:
- Paysafecard
- Neteller
- Skrill
- Bitcoin
- Apple Pay
- Google Pay
- Revolut Card
- Debit Cards
Best Online Casino Game Sites
Online casino game sites differ from online slot sites in their offerings. As the name suggests, online slot sites primarily focus on online slot games. Their advantage is the expansive game selection, encompassing various types of online slot games. Moreover, their bonuses are tailored for slot enthusiasts, often presenting opportunities for free spins and slot tournaments.
However, a limitation of online slot sites is their exclusive emphasis on slots. If you desire a change of pace and want to explore other gaming options, sites that offer both slots and table games would be more suitable. These casino sites provide not only slot games but also classic casino offerings like roulette, blackjack, poker, baccarat, and more. Their bonuses typically consist of matched deposits, which players can use on either slots or table games.
