Monster Casino Sister Sites 

Monster Casino was once on the Grace Media casino network but is now in the hands of ProgressPlay. Being a ProgressPlay Limited casino means that there are over one hundred Monster Casino sister sites. We’ve included some of the highlights of the range here – and a full review of Monster Casino and its various bonuses to go with it – but if you want to see every Monster Casino sister site, check out our ProgressPlay Limited page by clicking the highlighted link.

Winston Bet

Winston Bet logo

Some of the Monster Casino sister sites offer a more “complete” range of iGaming products and services than others. Winston Bet is a perfect example of that. There’s a full casino here with plenty of traditional slots and table games to offer, but Winston Bet differs from the majority of the casinos on the network by offering sports betting first and foremost. The promotions at Winston Bet are also themed around sports. There was a special volleyball betting tournament in progress at the site when we visited it to write this mini-review, which is one of the most niche promotions you’re ever likely to see at a UK casino site. The welcome promotion at Winston Bet isn’t much to write home about – it’s a simple £10 free bet if your first £10 wager isn’t a winner – but there are further promotions to consider in the casino section of the site. Players who spend a lot of time and money at Winston Bet should be able to help themselves to a few gifts from the casino’s rewards store.

Mr Vegas Casino

Mr Vegas Casino logo

Not to be confused with Mr Vegas, which is another popular online casino site operated by Videoslots Limited, Mr Vegas Casino tries its best to bring you all the thrills and spills of playing in a real casino in Sin City, Nevada, USA, condensed into a single casino site. In an effort to do that, it offers new players up to £400 via a series of matched deposit bonus offers when they’re new to the casino. The value of the offer is tempered a little by the x50 wagering requirement that’s imposed on it, but some players will inevitably still be tempted. The Vegas theme, however, is close to non-existent. The basic truth of a lot of the Monster Casino sister sites is that they’re virtually identical. Monster Casino is an outlier as it has a bespoke, unique design. The majority of the casinos on the ProgressPlay Limited casino network were put together with a fairly vanilla template. That’s why Mr Vegas Casino looks so much like Winston Bet, and it’s also why it’s essentially Winston Bet without the sports betting. Whether that matters to you or not probably hinges on whether or not you have any interest in betting on sports.

Monster Casino Mr Vegas Casino

Mr Slot

Mrslot logo

Mr Slot is a little more akin to Monster Casino than it is to the majority of Monster Casino sister sites because it wasn’t built using the template we mentioned while discussing Mr Vegas Casino. Nevertheless, it’s a step or two behind Monster Casino when it comes to both its appearance and its gaming content. The design of the site is bland and basic, doing very little to grab the attention of any casual browsers who might arrive on the homepage. The welcome offer of a 100% matched deposit up to £100 plus forty spins might grab a few eyeballs, but the wagering requirements of x50 will quickly have people looking away again. That high wagering requirement seems to be fairly standard across the entire Monster Casino sister sites range, so assume it applies to all of the casinos we discuss here unless we specifically state otherwise. There are few live casino games to go with the slots at Mr Slot, but the absence of Evolution from the casino’s providers list means the strength of the collection isn’t as good as it ought to be.

Vegas Mobile Casino

Vegas Mobile Casino logo

As you can see, Mr Vegas Casino isn’t the only Vegas-themed casino among the Monster Casino sister sites. There’s also Vegas Mobile Casino, which was designed and launched in a bygone age when it was necessary to code casino websites differently for laptops and mobile devices. That’s no longer the case, and so the old mobile-focused casinos look a little sparse by modern standards unless they’ve had a recent facelift. Vegas Mobile Casino has had no such facelift and could badly do with one. The casino’s website is so basic that it looks almost like something that a GCSE student might have knocked up as part of a piece of IT coursework in the early years of the 21st century. Minimalism is fashionable in web design, but looking old and basic very much isn’t. Again, the potential welcome package of £1000 in bonus funds via matched deposits might make up for the casino’s shortcomings in the eyes of some players, but only until they find out about the wagering requirements. The best-kept secret at Vegas Mobile Casino is that it has a sportsbook, which is hidden under the “betting” tab.

Dazzle Casino

Dazzle Casino logo

Until late 2023, Dazzle Casino was one of the most tired-looking of all the Monster Casino sister sites. It had been online for well over a decade by that point and hadn’t seen a single enhancement or improvement in all that time. The website was practically beginning to creak, and we wondered whether ProgressPlay had given up on it – but then everything changed. With a new logo and a new layout, Dazzle Casino is better than ever before. We still don’t think it’s outstanding enough to merit being called “dazzling,” but it’s vastly improved. The template that underpins the design of the new Dazzle Casino is the same as the one you’ll find at plenty of the newer Monster Casino sister sites, but there’s more to Dazzle Casino than there is to most of them. As proof of that, the casino offers a VIP rewards programme. You won’t find one of those at too many online casinos these days.

Dazzle Casino sister sites homepage


Gatobet logo

We mentioned that Winston Bet is rare among the Monster Casino sister sites because of its focus on sport. After Winston Bet, the next most sport-focused casino is GatoBet. It’s a confusing casino site because it doesn’t seem entirely sure about what it wants to be. The casino’s logo is a wolf on fire, which would be considered strange in any circumstances, but both “casino” and “sports” are highlighted as menu options on the homepage, almost as if whoever designed GatoBet couldn’t decide which area they wanted to focus on. Instead of focusing on either, they focused on neither, choosing instead to fill all the prime real estate on the casino’s homepage with a broad and general promotion for a 100% matched deposit welcome bonus capped at £200. The presence of the sportsbook makes GatoBet a cut above the average casino on this network, even if it is (yet another) example of the template being put to use, and there’s also a collection of live gameshows and live dealer games to keep players entertained.

Monster Casino sister sites Gatobet

Casino Kings

Casino Kings logo

Casino Kings might sound like an online casino with royal connections, but it’s delivered without any semblance of a regal theme. In fact, there isn’t much of a theme at Casino Kings at all, but that isn’t as much of a weakness here as it is at other Monster Casino sister sites. There’s plenty to admire about the site – not least its clever grouping of iGaming categories, which makes Casino Kings very easy to navigate. If you can’t find what you’re looking for at Casino Kings within a couple of clicks and a few moments of scrolling, it probably isn’t here. Most of the categories – slots, jackpots, live casino and so on – are standard and contain the same iGaming content you’ll find at several of the other Monster Casino sister sites. What makes Casino Kings different is its “casual” section. There, you’ll find a variety of hard-to-categorise casino games with arcade elements. All of the site’s scratchcard games are here, but you’ll also see Tetris games, virtual greyhounds, instant football, virtual tennis and oddities like Pachinko. If you’re a Tetris master and you’ve always wished you could make money out of your skills, now’s your chance.

Monster Casino sister sites Casino Kings


Interbet logo

We’re back to sports-focused Monster Casino sister sites again now, and we’re also back to the same old plain template that powers so many casinos on the ProgressPlay network. Interbet is more solid in its commitment to sports betting than GatoBet is, leading with sports-related promotions on its homepage, but it’s not quite as eye-catching or appealing as Winston Bet. The icy-blue, white and black colour scheme of the site leaves it all feeling a little cold, and the welcome promotion of a £10 free bet in return for an opening deposit (and loss) of £10 is no better than what you’ll already have seen elsewhere if you were to visit these casinos in the order they’re listed here. There’s no denying the depth and breadth of the sports betting options at the site – it even covers reserve-team fixtures played by League One and League Two football clubs in England – but navigating the options can be tricky and confusing. Mixing esports and virtual betting in with real sports betting doesn’t help much on that front. Like Winston Bet, Interbet also comes with a casino and live casino accessible through the relevant links at the top of the homepage.

Monster Casino Review 2023

The word “monster” has become a byword for “huge.” When we see the name “Monster Casino,” we’re naturally inclined to think about a massive casino stuffed to the brim with outstanding online slots, an expansive live dealer section, and all the promotions that we’d expect to see in a casino that thinks of itself as being part of the big time. Does Monster Casino, which has been online since 2017 and is operated by ProgressPlay Limited in Cyprus, live up to that billing? It’s a dual-licence casino with licences in both the UK and Malta, and it comes with a sportsbook to go with its general casino platform, but does it keep the big-time feeling going with the quality of its promotions and its standards of customer care? Here are the facts that will help you to decide.

Monster Casino sister sites homepage

Monster Casino Welcome Offers

The welcome package at Monster Casino would be worth up to £1000 in bonus funds – but only if you have the bankroll to reach that figure. Bonuses are available on a new player’s first five deposits with the site for a lasting warm welcome, but the deposit made has to be a minimum of £20 each time. After making their first deposit of at least £20, players receive fifty free spins on the legendary Book of Dead slot. Second deposits are matched at 25% up to a limit of £200, and third deposits are handled the same way. There’s a big boost available on fourth deposits, which are matched at 25% up to a cap of £600, and then fifth deposits come with fifty free spins on Starburst. All bonuses and free spins expire within seven days if they’re not used and come with a wagering requirement of x50. That requirement is significantly higher than the industry average.

Ongoing Promotions

There’s a fairly long list of promotions at Monster Casino, topped with a “rewards programme” aimed at providing players with a reason to keep coming back and spending money at the site. The rewards programme sees players tasked with “missions,” which might involve playing a certain game, logging in on a certain today, or completing a certain activity. Completing those “missions” sees players move up reward levels from one to tour, with rewards increasing at each stage. No further details about the rewards are given at the site – players only get to find out what they are once they’ve completed their missions – but it’s reasonable to assume that they’ll contain perks like free spins and matched deposits.

Almost every day of the week comes with an associated perk at Monster Casino, whether that perk is “Super Sundays,” “Friday Points Boosts,” “Saturday Spinners,” or something else, so you’d be very unlucky if you logged into Monster Casino and didn’t find at least one usable promotion waiting for you.

Monster Casino Pros and Cons

We’ll start with the pros, the biggest of which is the range of promotional offers at Monster Casino. From a welcome promotion that could be worth up to £1000 to a long-term reward scheme and a set of incentives aimed at making every day of the week interesting, Monster Casino seems to have all of its bases covered and covered well. This is a good-looking, well-designed casino site backed by a major casino network company and stacked with great games.

Despite what we just said, though, the promotions could also be seen as a downside. The welcome offer looks a lot less friendly once you realise that it comes with an x50 wagering requirement attached. That’s far higher than the industry average. Monster Casino could also be doing a lot better with withdrawal processing turnarounds. Even PayPal withdrawals can take up to seven days to reach your account, and there’s no valid excuse for that in this day and age.

Featured Slots and Casino Games

Unusually for an online slots website or a casino of any kind, Monster Casino doesn’t have a “featured slots” section. It simply lists a range of slots and invites you to browse through them. This isn’t necessarily the most user-friendly approach because it means players have no way of knowing what’s new, what’s old, or what the theme of a slot is, but at least it makes for a varied experience. The slots that are currently listed first in the Monster Casino archive are:-

Banana Split: You’ll always do well with an online slots game themed around a desert that so many people love. There’s a play on the word “split” here, though, because reels can be split during the bonus features to create two sets of identical symbols and double up the potential of big wins. It’s a slot that quite literally looks good enough to eat and is provided by Epic Industries with an RTP of 96% and lower than average volatility. 

5* Knockout: This slot, which comes from Northern Lights Gaming, aims to give you the feeling of being on a glitzy television game show. No fewer than four sets of mini-reels are positioned beneath your standard 5*4 set, and what’s happening on those mini-reels will determine your multiplier and whether or not you have any free spins to play with. Each star symbol that lands on the reels is collected, and once you have enough stars, free spins begin. 5* Knockout comes with 96.09% RTP and has surprisingly average volatility for a slot that looks so complex. 

Dynamite Digger Eureka: It takes a lot to make a slot with a mining theme looks cute, but this online slots game is Eyecon, and they somehow manage to achieve that effect with almost everything they release. Everything about the appearance of this 95% RTP slot tells you that it’s a basic creation, but then suddenly avalanche wins kick in, and you realise that it, like the mine in the background, has hidden depths. It’s not a lot that’s likely to make a lasting impression, but it’s entertaining despite its comparatively low RTP. 

We’ve already covered the fact that Monster Casino has a sportsbook to offer, but it also offers live game show and table games, scratchcards, and virtual table games to round out its portfolio.

Deposit and Withdrawal Methods

We mentioned our disappointment with withdrawal turnarounds at Monster Casino when we were discussing the casino’s pros and cons earlier on, but here’s the full picture. The number of payment options available at the site is actually pretty good. As you’d expect, you can use Visa, Mastercard, or Maestro debit cards to make payment. You can also use your Neteller, EcoPays, or PayPal e-wallet, or the Trustly bank transfer service. In terms of range, Monster Casino does well.

Here in the 2020s, players are accustomed to fast withdrawals if they’re using an e-wallet or similar service. Monster Casino insists on a processing time of one business day before any withdrawals are issued, so there’s no chance of getting your money instantly. After the single day of processing, debit card withdrawals might then take between three and seven business days to reach you. Even PayPal withdrawals could take up to seven business days, which is practically unheard of. Trustly and EcoPayz take three business days. Neteller is the fastest method available but is still comparatively slow at one day’s processing and one day’s transfer for 48 hours in total. Overall, Monster Casino lags behind the top runners in this respect.

Customer Support and License

There’s no way to speak to customer support agents at Monster Casino over the phone. You can email them, though, and live chat should be available 24/7 unless every operative is busy with other customers. The site’s FAQ section is fairly comprehensive, so you may be able to find what you’re looking for there.

Monster Casino is licenced via ProgressPlay Limited with the UK Gambling Commission (39335), and the Malta Gaming Authority (MGA/B2C/231/2012)

Monster Casino – The Verdict

Monster Casino is, overall, a fairly good online casino and slots website. It’s enhanced by the presence of its sportsbook, and its range of promotions brings excitement throughout the week and month for players that come here often. Unfortunately, though, there are a couple of elements here that can’t be considered customer-friendly. The first is the wagering requirement of x50 on bonus funds, which is far too high. The second is that the casino might take an entire week to get a withdrawal to you, even if you use a modern method like PayPal. That shouldn’t be the case, and it’s something Monster Casino should improve upon if it wants to catch up with the industry leaders at the front of the field.

Monster Casino – A Deeper Dive

Monster Casino has only been around since 2017, but its story is already quite long in a narrative sense. When it made its debut on the internet, it did so as a Nektan site. Back then, Nektan was one of the biggest operators in the business and ran dozens of successful casinos and online slots websites not only in the UK but also further afield. As you’ll already know if you’ve read the above review, that’s no longer the case. Nektan is no longer the operator of this casino; ProgressPlay Limited is. Even that doesn’t tell the whole story, though.

When Nektan stopped trading in the UK, every single one of its casinos became available for sale. Some of them didn’t find a buyer and have subsequently closed down. A significant chunk of the up-for-grabs websites was picked up by Grace Media Limited, though, and Grace Media ran them as a white-label operation before selling a few on to ProgressPlay and other casino network companies. That’s a common approach from this casino network company, which has well over one hundred white-label casinos under its umbrella. When we describe a casino as being “white label”, it means it’s run by someone other than the “name on the door” from a licencing point of view.

What Happened To Nektan?

If you’ve read this far, you might be wondering what happened to Nektan Plc. After all, we told you that they were once one of the biggest casino operators in the UK, and now they don’t trade in the country at all. There are several reasons for that, and the short answer is that if it were up to Nektan, they would probably still be active and trading in the UK.

In April 2021, the UK Gambling Commission suspended Nektan Plc’s licence to offer remote gambling services. This effectively made it impossible for them to offer gambling services over the internet and forced their hand when it came to the sale of their sites. This followed on from Nektan entering administration in April 2020 after getting into financial difficulties. The verdict of the UK Gambling Commission – which described Nektan as “unfit” – essentially ended Nektan’s existence. It was a sad ending for a company that had, until 2020, been a constant success story after launching in 2011 with sites like Monster Casino,, and Jackpot Mobile. At one point, the company traded on the London AIM Exchange. Now it doesn’t trade at all.

As we covered above, Grace Media Limited was the biggest beneficiary of Nektan’s woes. It picked up the company’s B2C assets for a cut-price £200,000. Had Nektan been able to continue trading, the company would also have received monthly fees related to this divestment. Unfortunately (or, from Grace Media and ProgressPlay’s point of view, fortunately), this isn’t the case.

The Monster Casino Blog

There isn’t much else to report about Monster Casino. It doesn’t advertise itself on television or YouTube. It doesn’t sponsor anybody or anything. It doesn’t even post on social media all that often. The last couple of years have been very turbulent for this casino brand, so it’s taking the time to lick its wounds, allow the dust to settle, and then gear itself up for another tilt at trying to make it to the top.

You can’t hear the “voice of Monster Casino” in advertising, but you can read it on the casino’s on-site blog. The colourful blog is updated with a couple of new posts every month, and they can be considered general interest browsing for anybody who has a passing interest in the casino industry. Topics covered include a list of books that might help you pick up roulette tips, the most popular online casino games in history, myths about casinos that far too many people believe, and specialist guides to blackjack and poker techniques. There isn’t necessarily anything here that you wouldn’t also find at another casino site, but the blogs are well written and might help to pass the time if you have nothing else to do.

Overall, Monster Casino is a quiet casino with a big platform. It might not shout about it – which is odd for a monster – but it lets the games and promotions speak for themselves.
