UK Online Slots: Top Seven Reviews
If you are itching to spin some slots, you'll likely get overwhelmed with the sheer number of available casinos. Each of these offers hours of endless fun. However, which one do you choose? Which one has your favourite slots or free games to try out and find your new favourite? The bonuses the casino offers are important. However, payment options that you can use to make a deposit or withdrawal at a particular casino can also influence your choice.
Don’t worry; we have you covered. We’ve tested probably one too many casinos to come up with this list, containing some of the finest slots online in the UK. Each of these sites is a solid choice, but let’s get down to explaining why.
18+. Bonus applies to new players only. 100% deposit bonus up to £300 on selected slots. £10 minimum deposit. 50x wagering requirements. Offer stands for 72 hours, wagering must be completed within 30 days. Neteller and Skrill not accepted for this bonus. All Terms and Conditions apply. BeGambleAware.org.
- Overall score: 8/10
- Welcome bonus: 100% Deposit Match up to £300
- Number of games: 600+
- Customer support: Phone, email, or live chat
- Mobile app: iOS only
Bonuses and Rewards
The first thing you’ll notice when you land on a casino site is its welcome bonus, so that’s where we’ll start as well. At The Sun Vegas, you will be greeted with a 100% first deposit match of up to £300. The minimum deposit amount is £10, and there is a 50x wagering requirement. The wagering requirement is pretty steep, especially when compared to other slot sites on this list.
Apart from a slightly underwhelming welcome bonus, you will also get some additional rewards through The Sun Vegas VIP program. To earn these, you have to collect comp points. Comp points are earned by playing certain games on the website. For example, you need to bet £10 on regular slots or £9 on progressive slots to get a single comp point. Later, you can exchange these points for real money.
Unfortunately, it takes a hundred points, or £1,000 spent on standard slots, to earn a single pound from this promotion. It is not the most tempting offer among the slot websites in the UK. If you rely heavily on bonuses and rewards for your playing, this might not be the best casino for you.
User Experience
The user experience at this casino fares much better than its bonus offers. The registration process is pretty quick, and you can make a deposit as soon as you create the account.
The navigation is well-thought-out, and you’ll be able to navigate through its more than 600 games with ease. The titles are all neatly divided into categories, and the site’s design allows for an excellent experience while playing on mobile devices as well.
Game selection
As we’ve mentioned before, there are more than 600 games available on this casino’s website. Most of these come from Playtech, a renowned developer of online slot games. You will have hundreds of slots to go through here, including progressive and jackpot games. However, you can also enjoy playing virtual sports and live table games such as roulette, blackjack, poker, and baccarat.
Banking options
Unfortunately, Sun Vegas is very limited when it comes to banking options. All the major options are covered, though. You can use your Visa or Mastercard card or make your deposit via PayPal or Skrill. The Sun Vegas also accepts the paysafecard. The minimum deposit is £10, and the maximum withdrawal limit is £50,000.
Customer support
The Sun Vegas customer support is astonishing. You can contact its team via phone, email, or even live chat, which is always a plus for a slot website. The knowledgeable team usually replies within a couple of minutes with a solution to your issue. However, the support is not available 24/7. Instead, the agents work between 8 a.m. and 1 a.m. GMT.
18+. Bonus applies to first deposit only. £10 minimum deposit, £75 maximum. Book of Dead has £0.10 spin value. 30x wagering requirement, 60x on Free Spins winnings. Wagering must be completed within 30 days. Free Spins must be used prior to the deposit. Bonus can be claimed within 72 hours after registration. Please play responsibly. BeGambleAware.org.
- Overall score: 8.5/10
- Welcome bonus: 100% Up to £75 + 75 Free Spins
- Number of games: 1,700+
- Customer support: Email or live chat
- Mobile app: No
Bonuses and Rewards
Lucky Vegas’ welcome bonus offer did not wow us and is underwhelming compared to other welcome offers from providers of online slots in the UK. The casino will match 100% of your initial deposit, which should be between £10 and £75. You also get 75 free spins for the Book of the Dead slot. The wagering requirement is reasonable: you have to wager the deposit and bonus amount 30x. There’s a catch, though - free spin winnings will have to be wagered 60x.
The casino also has several ongoing events that further reward the players. Daily picks provide free spins each day, and you can also enjoy monthly offers such as cashback rewards or special tournament invites. Players that join the loyalty program at this casino can enjoy several benefits. For example, they’d get access to special tournaments, faster withdrawal times, or even their own VIP account manager.
User Experience
Lucky Vegas casino offers an excellent user experience across the board. Signing up for an account at this slot casino is a straightforward and quick process. The site doesn’t require your banking information. The casino focuses on your typical Vegas aesthetics, and the navigation is very well thought out. Unfortunately, there is no free version of games to try out before committing to a particular one.
The casino is fully optimised for mobile devices. While there is no proprietary mobile app, you can still enjoy playing games via the casino’s mobile-optimised website.
Game selection
When it comes to game selection at Lucky Vegas, it is more than adequate, with an excellent variety of slot games. Other than online casino slots, you can also enjoy playing many variations of the classic roulette game. This casino also has a wide selection of card games you can play, such as poker, blackjack, and baccarat.
Banking options
The one thing that you will undoubtedly enjoy is the incredible amount of accepted banking options at Lucky Vegas. You can make your deposit via bank or electronic wire transfers, using your Visa, Mastercard, or paysafecard. It also supports many e-wallets and non-traditional payment methods such as Neteller, Skrill, Lottomaticard, GiroPay, ComGate, and Trustly.
Customer support
Customer support at this casino is good but not the best among the UK casino sites on this list. You can reach the support team through live chat available on the website or via email. The team’s working hours are from 6 a.m. to midnight each day, but the response speed is a bit underwhelming.
18+. Bonus open to new UK players only. 200 Free Spins are split into 3 deposits: 50 on the first deposit, 50 on the second deposit and 100 on the third deposit. £20 minimum deposit. Spins are only issued on selected games. 35x wagering requirements. Free spins expire within 24 hours. Offer stands for 21 days. All Terms and Conditions apply. Play responsibly.
- Overall score: 8/10
- Welcome bonus: Bonus up to €500
- Number of games: 500+
- Customer support: Email or live chat
- Mobile app: No
Bonuses and Rewards
Unlike some of its other competitors on our list, Griffon seems determined to wow you even before you sign up. Its exceptional welcome offer will allow you to get up to €500 in bonus funds through your first three deposits. Furthermore, you can expect 150 free spins. The welcome bonus is almost unmatched among casinos with slots games in the UK. The minimum deposit is €20, and there is a 35x wagering requirement.
When writing this review, there aren’t many other bonuses and rewards users can enjoy at this casino. However, since this casino is relatively new, it is expected to change in the future.
User Experience
Players that land at the Griffon Casino’s website will be pleasantly surprised with how streamlined its design is. The site is focused on the ongoing promotions and its extensive game library. Players will have no issues navigating the place, as the sidebar provides easy access to online slots, games, and promotions. You will also easily find the casino’s live chat customer support.
Griffon Casino is well-optimised for mobile devices, and there is no compromising the quality of playing when playing on the go. There is no need to download any apps - simply logging in to your account on your mobile’s browser will do the trick.
Game selection
Griffon casino is also an excellent choice for all slots enthusiasts. It has more than 400 slot games in its library. Here, you will find classic slots, but also jackpots and video slots. If you’re after legendary slots, the online selection here has titles such as Starburst, Mega Moolah, and Gonzo’s Quest.
Apart from this impressive selection of slots, players can enjoy playing card and roulette games as well. It has blackjack games, Texas Hold ’em, Jacks or Better, and Speed Roulette, American Roulette, and other variants of this beloved game. As a cherry on top, there are also live versions of the most popular casino games for that “real” casino feel.
Banking options
At the moment, Griffon accepts Visa, Mastercard, and Maestro cards. It also has several alternative deposit methods available, including e-wallets such as Skrill, PayPal, and Trustly, among many others.
Customer support
Griffon Casino is one of the rare slots sites available in English, Spanish, German, Norwegian, and Finnish. It has an extensive FAQ section for quick support. You can contact the customer support team via live email or live chat, the latter being open for business from 8 a.m. to 1 a.m. Central Eastern Time every day of the week. You can expect a prompt answer via live chat, but up to 24 hours of waiting time if you reach out through email.
18+. Restricted to new players only. £10 minimum deposit. Max bet with bonus funds £5. Live casino games are excluded from the bonus. 100% bonus up to £100 with the first deposit. 50% bonus up to £200 with the second. Skrill and Neteller are not accepted. Please play responsibly. BeGambleAware.org.
- Overall score: 8.5/10
- Welcome bonus: Up to £300 match for first two deposits
- Number of games: 700+
- Customer support: Social media, email, or live chat
- Mobile app: No
Bonuses and Rewards
Hyper Casino is one of the relatively new slot sites in the UK that offer a solid welcome bonus. Once you sign up for an account, you can get up to £300 with your first two deposits. The casino will match the first deposit you make 100% up to £100, and the second one 50% up to £200. The minimum deposit requirement is £10. The wagering requirement is a bit steep, at 45x.
Other promotions include a universal 10% cashback offer for balances below £10. There are also various ongoing competitions at all times, with the current ones being Agent Destiny and All Stars tournaments. Unfortunately, at the moment, there is no Hyper Casino loyalty program available, which is a common problem many new UK slots sites share.
User Experience
The registration process at Hyper Casino is exceptionally straightforward. It doesn’t require your banking details to get started. Once you register and start playing, you will notice that the site is very responsive. You can view the site’s content in five languages - English, Swedish, Finnish, German and Norwegian.
Unfortunately, there isn’t a mobile app, but you don’t need one, in all fairness. You can play it on any size screen without experiencing any delay or glitches, and the site will automatically adjust to your screen real estate.
Game selection
Hyper Casino is a great place to play slots games in the UK, as it has a selection of more than 700 titles. It covers all the classic and beloved games. You can also enjoy table games and live dealer versions of popular games. This casino even offers Slingo games - a popular hybrid of slot and bingo games.
Banking options
You can also count on a decent selection of payment methods available at Hyper Casino. Its players can make deposits via Visa, Mastercard, ecoPayz, and Interac, among many other options. The minimum deposit amount is £10.
Customer support
Hyper Casino’s customer support is available through several channels. Players needing help can reach out to the customer support team on Facebook, Instagram, and Twitter, which is not common among other slot websites in the UK. You can contact them via live chat available on the website or send them an email. There is an extensive FAQ section on the site, which will prove to be a faster way to get the help you need, as, in our experience, the customer support team was not very quick to reply.
18+. Only new players are eligible for the bonus. £10 minimum deposit, £5 maximum bet using bonus. 40x wagering requirement. Offer stands for 14 days. 30 spins on selected games will be issued momentarily, the remaining will be issued in 9 days, 30 spins each. Free Spins bonus stands for 72 hours.

However, you also get 300 free spins that you can use on some of the most popular slot games, such as Starburst, Red Riding Hood, Gonzo’s Quest, or Aloha.

Apart from the more-than-welcoming bonus for newcomers, this casino also has numerous weekly promotions. Some of the weekly promotions include free spins and deposit bonuses, such as the 25% Fab Fridays bonus and free spins each Tuesday.
The VIP program at this casino includes getting access to your personal account manager and even more promotions. The VIP program here is the best among the slot sites in the UK listed here. VIP users can also look forward to quicker responses for customer support, birthday gifts, and VIP prize draws.
User Experience
Kassu is one of those casinos that is pure joy to look at. It has a unique and somewhat quirky design, excellent navigation, and great categories. You can effortlessly search for games on this casino’s website. All the games have free demo versions - you can try out new games as much as you’d like to find your next favourite.
Game selection
Kassu has more than 1,300 games in its arsenal, a thousand of which are slots. Slot enthusiasts can enjoy video slots, classic games, regular jackpots. New slots come online all the time, so there’s always something to check out. You can play Megaways Slots or Must Fall Jackpots as the site offers these unique game types. If you prefer the classics, you will also find the Book of Dead, Starburst, and other popular titles here.
In addition to the aforementioned games, you can also find a solid collection of card games here, including baccarat, poker, and Texas Hold ’em. There are more than 40 live dealer rooms just for baccarat! Apart from card games, you can also enjoy plenty of live dealer and video roulette games.

Bonuses and Rewards
Slots Heaven is precisely that - one of the greatest gaming sites in the UK and a heaven on Earth for slot enthusiasts. It has a very enticing welcome bonus waiting for new players. The bonus matches the initial deposit 100% up to £100 and awards new players 200 free spins on the Age of the Gods slot. The only downside is the wagering requirement - the spins have only 20x, but the deposit bonus comes with a 40x rollover requirement.
If you are a fan of neon lights, you’ll enjoy the overall design of this casino. The website is nicely streamlined, and the navigation is well-thought-out. Unfortunately, all of the games run from a pop-up window. Many players will have to tweak their browser settings to enjoy their daily dose of casino slots online, especially if they use adblocking software.
Game selection
This casino has about 400 games on its offer, all from the industry’s most reputable game providers. You will find more than enough slots to enjoy, but also table games, jackpots, and live casino titles. The “Age of the Gods” is clearly the casino’s favourite and most promoted game, which you can see from the moment you take a look at the welcome bonus. Don't worry, though: you will be able to find plenty of other exciting slots, too.
Banking options
This casino certainly has the most extensive list of available payment methods - more than 20 of them. You can make your deposits via Skrill, Neteller, PayPal, debit cards, bank transfers, and much more. This casino is also the only one among our UK slot sites in this article that accepts deposits in Bitcoin. The minimum deposit amount is £15.
Customer support
The customer support at Slots Heaven is exceptional. The agents are friendly, knowledgeable, and ready to help. You can reach them via phone or send them an email. If you have a complex issue you need to resolve, you should opt for email, as you’ll get more detailed information. The website also has an extensive FAQ section, covering most of the most commonly asked questions.
18+. Bonus applies to new customers only with the first three deposits. £10 minimum deposit, £500 and 150 spins maximum bonus. 30x bonus and spins wagering requirements, 4x conversion. Available for selected slots only. All Terms and Conditions apply.
- Overall score: 9/10
- Welcome bonus: Up to £500 Welcome offer + 150 spins
- Number of games: 450+
- Customer support: Phone, email, or live chat
- Mobile app: No
Bonuses and Rewards
The welcome bonus at this casino can be as high as £500, which tops all other online slots bonus offers on this list. You also get additional 150 free spins on specific slots. The welcome bonus is divided among multiple deposits. The first deposit gets you a 100% match up to £100 and 100 free spins. The second is matched 50% up to £100, and the third offers a 50% match up to £300. They offer 25 free spins each.
The minimum deposit requirement is £10. This casino also has the lowest wagering requirement on this list at just 30x, but be aware that you’ll have to wager both your deposit and the bonus.
Winners’ Club features many weekly promotions. For example, you’ll be able to enjoy a Game of the Week promotion, or Spins Match, which awards you with 20 free spins after depositing £10 or more. Each week, players can earn cash prizes, matched deposits, or bonus spins.
User Experience
Winners’ Club has one of the best website designs out of all sites with casino slots in the UK we’ve covered so far. It is modern and sleek, but most importantly, easy to understand and navigate. Everything is just a click away, and you won’t have any trouble finding what you need. Mobile optimisation is excellent, so you won’t miss the lack of a dedicated Android and iOS app.
Unfortunately, there are no demo versions of the games on the site, so you’ll have to know what you want to play before committing.
Game selection
Currently, this casino offers more than 400 slots to its players. Players can find some of the most popular slots and games here, such as Starburst, Jumanji, Mustang Gold, and Conan.
While the site has many slot games and even Megaways slots to offer, it doesn’t have a wide selection of other games. There are around ten roulette games, half of which are live games, and about 20 different casino games. You will be able to find a few live dealer games, craps, baccarat, sic bo, and blackjack games, too, but nothing to write home about.
Banking options
You can currently make your deposit through AIB, Paydoo, Paypal, Skrill, Neteller, Trustly, and Boku at this casino. The casino accepts US dollars, British pound, euros, and Swedish krona. The minimum deposit amount varies heavily depending on the currency of your choice.
Customer support
Customer support at the Winners’ Club is exceptional. Out of all the casinos we’ve tested while trying to find the best slot sites in the UK”, this one certainly had the most polite and patient support staff. The customer support team is available by phone, email, or live chat, and their working hours are from 8 a.m. to 12 a.m. GMT each day of the week.
A Quick Guide To Choosing Your Favorite Slot Sites
As many new websites are launched almost daily, it can become a mission to sort out the good from the bad ones. To help you navigate the world of slot sites in the UK, we’ve covered some of the best options on the market and reviewed them in detail.
When it comes to finding your favourite casino, you likely have a list of things you like or find essential. Depending on your priorities, you might find a good user experience more valuable than a wide selection of games. For other players, the welcome bonus and wagering requirements may dictate which casino will get chosen as their new online gambling home.
So, the first elements of the casino offer we covered in these reviews of slot games for UK players were welcome bonuses and rewards programs. From there, we’ve discussed the website’s user experience, sign-up process, and whether a website was a breeze to use. We have also covered game selection, banking options and gave you a quick overview of what you can expect from its customer support team. By following a similar train of thought, you too can quickly rate the casinos you run into and find your favourites.
What is the best online casino site in the UK?
It is up to you to decide which casino is the best as you very likely have your own set of preferences. From our list of the excellent UK slots available online, Griffon casino and Winners’ Casino offer the largest welcome bonuses at the moment. Both also give a lot of free spins. However, while these may be the best welcome offers on the list, Lucky Vegas has the best customer support team and a ton of games, Kassu offers a wide variety of slots etc. Read our reviews carefully, and decide what is most important to you.
Which online slots payout the most?
If you want to know your odds, you should certainly do your research about Return to Player (RTP) percentages. The slots that have the higher rates will payout more often than those that don’t. If you want to have the edge over the house, look for slots with an RTP percentage of over 90%. Gonzo’s Quest and Starburst are excellent choices, as is Immortal Romance.
Is it easy to learn online slot rules?
These new online slots certainly look nothing like the good old one-armed bandits. Multiple lines, wagering limits, and special features make it a bit more complicated than we’re typically used to. It might take some time, but understanding how to play slot machines is not that difficult, and we’re confident it won’t take you a long time to get to grips with it.
Are online slots sites to be trusted?
The answer to this question depends on the casino. Most of the casinos and almost all of the UK slot sites we review are fully regulated. Often, they are part of a larger group of casinos that employs reliable casino games developers and focuses on providing excellent security and safety. However, there are also those that are far less trustworthy. Let’s put it like this: all of the casinos on this list are reliable and safe. Still, as always, make sure to do your research before you make your first deposit.
What’s the best online slot?
It would be unfair to award any of the games the title of the best - it all depends on your preferences. However, when writing this list of best slot sites in the UK, we found several slots worth mentioning here. Ugga Bugga slot by Playtech has an RTP of 99.07%. The Mega Joker slot from NetEnt also has around 99% RTP, and you can try The Catfather by Pragmatic Play, which has an RTP of 98.10%. There are also many other great slots with excellent RTPs, and you should most certainly check all of them out to find the perfect one for you.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
