The best Mr Sloty sister sites for UK players in 2026
Mr Sloty casino operates under a Curacao licence and they currently have no alternatives. It was launched in 2020 by MRSL N.V (and also operated under a master license by Curacao) and then it had several alternatives but those have closed down and, even after the change of ownership to the current Mr Slotty Ltd company the site remains a standalone brand. Still, if you'd like to enjoy some high tier gaming experience, I've got some recommendations on the best alternatives to Mr Sloty that you might enjoy, as well. And let's see which those are.
7Abet
One of the best Mr Sloty's alternatives is 7A bet. That's among my favorite non Gamstop casino and betting sites which provides a wide number of promotions. They might have lower max amounts than what you'll find with Mr Sloty but I consider them more valuable and I especially enjoy their live dealer promos. And the collection of live dealer games, too.
Mystake
Mystake is one of my favorites within the world of online casinos because they offer a high tier gaming experience with numerous popular games and a wonderful variety of betting markets. Great odds, numerous jackpots, some Provably Fair games, as well as an exciting design both on desktop and on mobile all await you here.
Velobet
Another popular casino also providing you with a really high tier gaming experience (even better than Mr Sloty) is Velobet. They've got some of the highest bonuses I've seen around recently and the selection of games is also up to basically all my standards. And then you've got the numerous sports betting markets including on eSports, together with the great selection of horse racing events to wager on, including some with quite the high odds.
Goldenbet
Goldenbet is also a top pick when browsing around for some Mr Sloty alternatives. They ensure a really exciting online casino and betting experience that's made even better with the numerous free spins and free bet bonuses which you'd be able to enjoy. Those are all coupled with a great VIP system, the seamless user experience and the perfect mobile optimization of the site.
Cosmobet
Cosmobet is among my favorite non Gamstop sites also because they not only present you with numerous crypto currencies to use as a payment option but also have some great Provably Fair games. That's just a scratch on the surface of all they offer, though, and it's coupled with fast payouts, great games and a comprehensive sports betting coverage.
Rolletto
Or you can test your luck with Rolletto casino and sports betting. That's also an offshore licensed gambling platform that's completely crypto-friendly and ensures you'll have a wide variety of options to pick from, both in terms of top-tier slots and jackpots and when it comes to live dealer tables and betting markets on traditional, niche and eSports. Of course, the bonuses are also both abundant and really varied, ranging from welcome offers through ongoing free spins promos, cashback and numerous tournaments.

Mr Sloty casino review of bonuses and promotions for new and existing players
If you'd like to enjoy some great bonus offers, Mr Sloty casino provides you with plenty of opportunities to do so. Like many online casinos outside the UKGC's regulations, the site provides a welcome package that covers your first few deposits and I'm going to take a more detailed look at it, together with all the other promo offers available here.
Welcome bonus package
Mr Sloty casino has a generous welcome bonus that provides new customers with 400% match on their first deposit up to a max amount of as much as £2,000. Together with the bonus funds, you'll be provided with 100 free spins, too, which you can use on the Narcos slot. The minimum deposit required to activate the offer is £20 (bonus code SLOTY1) and wagering requirements of 30x apply.
But that's only the first part of the welcome bonus package. Then you'll be able to claim another four parts, as well. The second of those is provided on your second deposit of min £20 (bonus code SLOTY2 required) and offers you 200% match up to £1,000 together with 50 free spins on Sweet Bonanza.
On your third deposit of at least £20, if you use the code SLOTY3, you'll be provided with additional 150% match up to £1,000 together with 50 bonus spins on Gates of Olympus. The fourth and the fifth parts are claimable with the respective SLOTY4 and SLOTY5 bonus codes and both credit you 100% match up to £1,000.
Same 30x wagering requirements apply on all the parts of the welcome package.
Sports first deposit offer
The casino could have done much better with their sports bonus. Currently they provide you only with an up to £30 free bet offered on a minimum deposit of £20 with the promo code WelcomeSport. You can use your bet token only on events with odds of 10 and only net winnings will be credited into your account.
Ongoing bonus offers
There are some additional promotions you can make use of with Mr Sloty, as well, such as the weekend offer available on min £25 deposits with the code MAXWIN that credits you up to £1,000 in bonus cash plus 100 free spins on Berry Burst Max.
Other reload offers are provided, as well, once more crediting you with free spins to use towards selected games. And the site provides you with some special missions which make the gameplay even more thrilling wheras at the Mr Sloty Shop you'd be able to turn the points you've accumulated into bonus money or free spins.
Popular casino games to enjoy with Mr Sloty
There's a great collection of games provided at Mr Sloty online casino and even though their library isn't exactly the most comprehensive or thrilling one, it still provided me with a high quality experience.
Slot games
Mr Sloty casino's slot games include some of the best online titles that are popular among all players in the UK. Casino enthusiasts will certainly be thrilled to discover the numerous hot picks such as:
- Big Bass Xmas Xtreme
- Big Bass Halloween
- Book of Tut
- Gates of Aztec
- Sugar Rush
- Gates of Olympus 1000
- Sweet Bonanza Super Scatter
- Gonzo's Quest
- Coins of Ra Power Hold & Win
Actually, the casino presented me with a completely different selection of Hold & Win titles which let me find all the games with this type of mechanic in one place. They've done the same for the lots of Megaways games like Rise of Samurai, Curse of the Werewolf, Lady Wolf Moon and Aztec Magic. A separate game selection of Bonus Buy slots was also offered, together with the numerous jackpot titles, although the most popular mechanics (think Dream Drop, Mega Moolah and Jackpot King) weren't featured.
Table games
The casino boasts numerous table games like blackjack, roulette, baccarat and video poker, too. Whether you'd like to experience some standard varieties of all those or thrilling multiplier tables and additional alternatives such as Red Dog, Pontoon, Pai Gow or Top Card Trumps, you'll find no issues whatsoever.
Live casino games
The live dealer game library is providing you with quite a lot of options but you need to keep in mind they do not feature titles by the best of the best game providers like Evolution Gaming and Pragmatic Play. Their live tables are supplied by 7Mojos, Betgames and Vivo and although you'll see plenty of enjoyable options, the quality is just not the same. The casino claims to offer a wonderful live experience and it's true, at least to some degree, mainly because you'll be able to pick among a wide number of classic and multiplier roulette, blackjack and baccarat tables. Teen Patti, Dragon Tiger, War of Bets and some other game shows are also available with one of my favorites here being Crypt of Giza.
Software providers
Mr Sloty casino ensures that players will be able to enjoy a secure and fair gaming environment thanks to partnering with numerous of the best iGaming developers for its extensive selection of games. And those include:
- Pragmatic Play
- Play'n Go
- Microgaming
- Endorphina
- Betsoft
- Tom Horn
- Amatic
- EGT
- Gamzix
- Spinomenal
- Wazdan
- Novomatic
- Gamomat
- Onlyplay
- Merkur Gaming
All that means you can be safe you're getting guaranteed fair play and a great variety of opportunities.
Mr Sloty sportsbook: Best markets, odds and betting features
Mr Sloty offers a great sports betting section, as well. It's got an easy to use setup where all the markets and odds are clearly visible and the available fixtures are within the thousands. Of course, the biggest variety of those is on football where you'd see both the top-flight and the lower division championships, together with all the international matches including the ones from the World Cup.
Along with those you'll be able to bet on tennis, volleyball and horse racing, along with basketball, cricket, american football, baseball and lots of others. Mr Sloty covers some eSports also but those are only Counter-Strike, Dota 2, League of Legends and Valorant so the options aren't as varied as you might be used to seeing.
I greatly enjoyed the specials, though, as well as the selection of parlays, along with the plenty of live betting options, some of which included live streaming, too. The variety of betting features isn't really exciting but at least twice weekly you'd be offered a special promo offer allowing you to deposit £50 and get £50 in free bets.
The general experience is about market average with the odds fluctuating between rather good and not that worthy.
Payment options provided at Mr Sloty casino
The casino offers you to use various payment options to get started with your online gambling journey and those include:
- Visa and Mastercard
- Skrill and Neteller
- Revolut
- Neosurf
- Astropay
- Flexepin
- paysafecard
- Cashlib
- WebPayz
- Bank transfer
Lots of crypto currencies can be used for deposits and withdrawals, too, including Bitcoin, Litecoin, Ethereum, Dogecoin and several others.
But despite the numerous payment methods provided and the availability of crypto, there are some issues when it comes to the financial transactions with Mr Sloty. First, they limit how much you can withdraw. If you've deposited less than £200 overall, the max payout is set at 10x your last deposit and all money above that limit will be voided.
Also, if you'd like to request an amount over 5x your lifetime deposits, the money will be released in tranches of £5,000 per payout. Second, there's too long of a pending period, up to 48 hours, for withdrawal processing. Which means you might need to wait quite a bit to get your money out.
And last, but not least, when I took a look at the player reviews available at Casino Guru's complaints page, there were just too many of those. Especially related to withdrawals being held for no reason or being delayed quite a bit. So, if you'd like to check out Mr Sloty, be wary that you might experience some similar issues.
Mr Sloty customer support
If you need to reach out to the support team at Mr Sloty, you'd be able to easily do so via the live chat they're providing you with. My main issue with this option is the fact that you need to first go through their bot and only then you can be redirected to a real human. At least the responses they provided me were professional and actually helpful. And they're active 24/7 so that's a big advantage. The site is supposed to provide support via email, as well, but I didn't manage to find their email adress, so... I'm not exactly sure how that contact channel should work.
Pros and cons of Mr Sloty casino and sportsbook
| Pros | Cons |
| Generous bonuses including a welcome package reaching up to £6,000 plus 200 free spins | It's not licensed by the UKGC |
| Various games provided including Bonus Buy and jackpot slots | Long waiting times on withdrawals |
| Crypto payments accepted | Max withdrawal limits tied to your deposits |
| Pre-match and live betting markets easily available | Live chat takes you through the bot first |
| Lots of player protection measures including SSL encryption | There aren't that many popular jackpot mechanics |
| Native app available for mobile devices | The sports betting bonuses aren't really good |
Responsible gambling with Mr Sloty sister sites
Mr Sloty casino might not be licensed by the UK Gambling Commission but their team does their best to ensure a responsible gaming environment. So you'd be able to set up limits on your deposits, restrict how much you can spend or lose, as well as activate notifications about the time you've spent playing. And the site also provides you with time-out and self-exclusion periods which you can activate as needed.
The main drawback, of course, is the casino not being on GAMSTOP which means vulnerable individuals with gambling addiction who've signed up with the UK's self-exclusion scheme lack the protection that the programme offers.
Mr Sloty review conclusion
Mr Sloty is one of the many non Gamstop casino and betting sites which are somewhere between good and not so good. The platform does feature a few good options here and there and they try to present you with numerous bonuses, games and betting events.
The general experience isn't the best, though, especially when you consider the issues with withdrawals. And since they don't have any sister sites, Mr Sloty remains your only option of checking out what the company behind them can achieve which, I hope, will become better in the future. As for now, though, I would actually recommend checking some of the alternative sites which I've shown you above so as to avoid the risk of having some payout issues at Mr Sloty.
