Mr Slot Sister Sites 2026

Ruby Bet

You can, to an extent, divide the Mr Slot sister sites into two categories. There are brands on the ProgressPlay Limited network that focus on casino games, and other brands that focus on sports. Ruby Bet belongs to the second of those categories. Because of that, you might not think of it as a decent alternative to a casino called “Mr Slot,” but you’d be wrong. Even the sports-focused sites on this network come with the full complement of 3000+ slots available to this operator, so Ruby Bet is just as good a bet (pun intended) as the rest of them. It’s one of the more basic sites in the range, though, built on the fairly drab template that ProgressPlay uses for its secondary brands. It can offer you a decent time and an excellent range, but there’s nothing about Ruby Bet that’s especially memorable.

Dazzle Casino

Dazzle Casino has been online since 2012, which makes it one of the oldest of the Mr Slot sister sites. It’s been through a few revamps during that time, and its current look sets it apart from most of the casinos and betting sites on the ProgressPlay Limited platform. The template-driven look is, as we noted while we were talking about Ruby Bet, quite a drab one. Dazzle Casino has a style that’s all its own, and while it might not be as dazzling as its name suggests that it ought to be, it looks fine and it’s easy to use. The welcome bonus available to new arrivals at Dazzle Casino is also usually a cut above what you’ll get from a standard casino on this network. We think the information on the homepage is outdated, though – it claims to have only five hundred slots, but the true number is far higher.

Hippozino

One of the most consistently true rules of the online casino scene is that casinos that have animal themes or animal mascots tend to perform better than casinos that don’t, and Hippozino is a good demonstration of that idea in action. It’s another one of the Mr Slot sister sites to have a unique, purpose-built design, and it catches the eye immediately with its fiery design. There’s no sign of an actual hippo anywhere, which is a little odd given the casino’s name, but it’s brightly coloured and sure to grab your attention. Sadly, there’s more sizzle at Hippozino than there is steak. What we mean by that is the welcome promotion is smaller than we’d expect from a supposedly top casino on this network, and the “Casino Anywhere” concept is clapped out now that every casino worth its salt is optimised for mobile play.

Sin Spins

Sin Spins used to be a much more attractive casino than it is now. In days gone by, it made the most of its “Sin” concept with a devilish theme complete with a hellish backdrop and an attractive she-devil waiting to greet you on its homepage. That look got scrapped in 2024. We’re not sure why it happened, but if we had to guess, we’d say that somebody at ProgressPlay decided that using half-dressed female models to attract players to online casinos was dated and sexist. We have no comment to offer on that front, but we do think that it’s a shame Sin Spins now looks just like a dozen or more of the blander Mr Slot sister sites, and no longer has anything that could be classed as a unique selling point. It’s still a perfectly fine option if you just want to spin a few slots, though.

Fruity King

Fruity King is a casino that’s starting to look and feel its age after being left online largely unchanged since it first launched in 2014. Weirdly, there are actually two versions of this brand available among the Mr Slot sister sites – one that focuses on players in the UK, and another that has a .nz extension and caters to players in New Zealand. We don’t know why the New Zealand version of the brand is also available in the UK, but if you’re going to play at one of them, stick with the UK version if that’s where you live. Despite looking a little tired, Fruity King offers a perfectly acceptable welcome bonus to new players, and makes all of its top slots very easy to find by laying them out with massive thumbnails on its homepage. Surprisingly, it also offers sports betting.

Mr Slot Review 2026

Mr Slot is blessed with a bespoke layout, which isn’t something we can say for most of the casinos on the ProgressPlay Limited network. Granted, it isn’t a very attractive layout, and it would benefit enormously from some modernisation, but at least it isn’t one in a series of more than thirty lookalike casino sites. The Mr Slot brand has always been a consistent performer for its operator despite never being the best or most popular casino on its network, but how’s it holding up in the here and now? Let’s see.

Mr Slot Welcome Offers

The welcome promotion at this casino hasn’t changed in years. It’s a 100% matched deposit with a maximum value of £100, and it comes with forty bonus spins. It’s a bit of a bread-and-butter bonus, but there’s nothing wrong with the amount of cash or the number of spins on offer. Our issue with the promotion comes from it wagering requirements. They’re set to x50, which is far higher than the average for casinos in the UK, and stacks the deck too heavily in Mr Slot’s favour. Players don’t stand a realistic chance of turning the bonus cash into real cash.

Ongoing Promotions

Firstly, Mr Slot has access to the same “Rewards Store” as almost all the other Progress Play Limited casinos. It’s the operator’s equivalent of a VIP reward system, and it sees players accrue points through making regular deposits and playing games. Those points can then be traded for rewards within the store, which usually consist of free spins packages, matched deposits, and bonus cash. With a lot of casinos on this network, the bonuses stop there. That’s not the case with Mr Slot – there’s more to discover.

Every weekend, players can take advantage of a 50% matched deposit worth a maximum of £100, and get fifteen free spins as part of the bonus. The same x50 wagering requirements from the welcome promotion are here again to spoil the fun, though. There’s also a “Monday Reward” of 50% up to £25 on deposits and another twenty spins, with the same nasty strings attached. Fridays bring a 45% matched deposit boost up to £45 and fifteen more bonus spins, and free spins on selected slots are available every Wednesday to players making deposits that day.

What are the Pros and Cons of Mr Slot Casino? 

Pros: Mr Slot’s unique look makes it stand out from the ProgressPlay Limited crowd. As with every casino on this operator’s platform, it comes with thousands of slots and receives fresh stock every week. There’s always something new to play.

Cons: The promotions and bonuses are all ruined by the wagering requirements attached to them, which are far too high. Withdrawals are too slow, and come with fees attached. The whole casino feels behind the times when it comes to customer service.

Featured Slots and Games

Mr Slot Casino lives up to its name by going all-in on slot games, offering an enormous reel-spinning roster with barely a nod to anything else. From ancient myths to birthday parties and samba carnivals, the themes are wildly varied. Players can dive into Temple of Iris, Thunderstruck II, Dumb and Dumber Route to Riches, or even Cup Carnaval, with Megaways titles like Zillard King adding a modern twist. The emphasis on quirky, colourful games like Sugar Bonanza Deluxe and Will It Ring: Box Breaker helps keep things playful, if occasionally chaotic.

The rest of the site sticks to that single-minded focus. There’s no live casino to speak of, and while blackjack and roulette show up in slot-based formats, they sit firmly in the shadow of the site’s core offering. Big progressive jackpots make an appearance via the likes of Mega Moolah, Diamond Link: Mighty Viking, and Irish Luck Jackpot, though again, they feel secondary to the main slot push. If you’re after a no-frills, spin-heavy experience with nothing to distract from the reels, Mr Slot delivers precisely that – just don’t expect any live dealers to be waiting in the wings, or anything other than what its name suggests.

Deposit and Withdrawal Methods

Finding a way to conduct business with Mr Slot won’t be a problem. All major UK debit cards are accepted, and there’s decent support for e-wallets, too, with PayPal, Payz, Neteller, and Skrill all making the cut for inclusion. If none of these options float your boat, you could instead use Apple Pay, a Paysafe card, or ask for a bank transfer. The issue we have with the payment system at Mr Slot is that the whole thing moves so slowly. There’s a twenty-four hour processing period for all withdrawals, so instant cash is impossible. Beyond that, you’re looking at 3-7 days for PayPal or debit cards, three days for Payz and Apple Pay, and at least an extra twenty-four hours for bank transfers and other e-wallets.

Customer Support and Licence

Mr Slot’s Contact page says that the casino offers live chat, but doesn’t provide a link to it. We can’t find any way of accessing chat anywhere else on the casino’s website, so we assume that it doesn’t actually offer it at all. As such, all you can do is email customersupport@instantgamesupport.com, which is the catch-all address that ProgressPlay Limited uses for all the brands under its umbrella.

Speaking of ProgressPlay Limited, the operator holds UK Gambling Commission licence number 39335. This is the same licence that covers all of the Mr Slot sister sites, and was clean on the day this review was written. That means no fines, no settlements, no warnings, and no other regulatory incidents. We’ll update this review if that changes.

Mr Slot: The Verdict

Mr Slot is better than the bog-standard template-based casinos on the ProgressPlay network, but that isn’t saying much. It might find some fans among hardcore slots enthusiasts who don’t want to play casino games of any other description, but even if we look at it as a niche casino, it’s still poor when it comes to customer support. Withdrawals aren’t fast enough, there’s no live customer support, and the bonuses aren’t player-friendly. There are several obvious ways in which Mr Slot could be improved, and it’s within the operator’s power to make those improvements. We hope they get around to it one day – the Mr Slot brand is beginning to look a little tired.
