Cosmobet Sister Sites

Santeda International B.V. has built its name mainly on the success of MyStake Casino, which draws players from across the globe. That said, it isn’t limited to a single flagship brand, as the company has several other casinos worth mentioning, with Cosmobet being one of them. We’ve outlined the other Cosmobet sister sites for you further down the page. Still, a casino’s global popularity doesn’t automatically mean it holds the right licences in every region. If you’re reading this from the UK, it’s important that you pay close attention to the following notice before you go any further.

MyStake

It’s impossible for us to say that we’ve tracked down all of the Cosmobet sister sites due to the opaque nature of their parent company’s Curacao-based licensing, which lacks the clarity and transparency of regulators like the UK Gambling Commission or the Malta Gaming Authority. Therefore, while MyStake is well-known among UK players as a non-UKGC casino, there could potentially be more Cosmobet sister sites yet to be discovered by us. Despite UK guidelines cautioning against playing at non-UKGC licensed casinos, a frankly worrying number of UK players still opt for MyStake and appear satisfied with their experience.

MyStake distinguishes itself from typical Curacao-based casinos through its exceptional range and quality of entertainment offerings. The name ‘MyStake’ implies a focus on sports betting, and the platform indeed excels in this area, particularly with football events. Beyond sports betting, MyStake delivers an all-encompassing casino experience, including live casino tables and game shows with real dealers, each accompanied by distinct promotions. The platform collaborates with top game providers and even presents exclusive games like Plink. Were MyStake to be regulated by a more recognised licensing body, we’d be happy to rate it as a premier iGaming destination.

Rolletto

Rolletto is similar to MyStake Casino in a lot of ways, and we’re not just talking about the fact that both of them are Cosmobet sister sites. Like MyStake, Rolletto offers a combination of traditional iGaming alongside sports betting, esports betting, tournaments and more. Also like MyStake Casino, Rolletto Casino targets players in the UK despite not having a licence to do so. That raises questions about how trustworthy this casino and operator is, regardless of how much players in the UK appear to enjoy the sites.

There’s a lack of pizzazz at Rolletto when you compare the site directly to MyStake or Cosmobet. Its style of presentation is somewhat lacking, and it doesn’t have a theme to help itself stand out. For those who value content over aesthetics, though, our understanding is that Rolletto offers a broadly comparable experience to the other Cosmobet sister sites, perhaps even outperforming one or two of them when it comes to things like promotions.

Goldenbet

Goldenbet, though not as prominent as (for example)  MyStake Casino, serves as an intriguing alternative within the Cosmobet sister sites. A visit to Goldenbet reveals that the site has striking resemblances to both MyStake Casino and Velobet (we’ll get to that one in a moment), hinting at the use of a template by the operator to ensure uniformity across these platforms. They all offer a similar assortment of gaming options, with Goldenbet’s homepage featuring menu categories almost identical to those found at MyStake Casino, further highlighting the consistent approach across these sites.

In terms of visual charm, Goldenbet doesn’t quite reach the heights of Cosmobet. It showcases the same slot games but misses out on the custom thumbnails that lend Cosmobet an extra edge in aesthetics. Nonetheless, Goldenbet strives to differentiate itself with its promotional strategies. A notable offer from Goldenbet is the ten per cent cashback on all daily losses, a feature with no maximum limit. This could be a particularly attractive proposition for players who wager large sums, assuming the casino honours this commitment. We can’t be sure of that, given the fact that it’s a Curacao casino.

Velobet

Velobet presents a strikingly modern and futuristic aesthetic, distinguishing it visually from other Cosmobet sister sites. While its sophisticated design and somewhat enigmatic name don’t immediately clue visitors in about which aspect of iGaming Velobet focuses on, we’re happy to confirm that this is, first and foremost, a sports betting platform. The other Cosmobet sister sites also offer sports betting, but not with the same sense of speciality as Velobet. This focus is evident from the scrolling banners on its homepage, which promote offers like a free bet for every four bets placed on the site.

On top of the above, Velobet stands out from the crowd by supporting cryptocurrencies for both placing and settling bets, offering a distinct approach compared to UK-based casino network sites. However, in the realm of Curacao-based casinos, the acceptance of crypto betting is quite common. With a more subtle presentation than its counterparts in the network, Velobet may hold a unique appeal for those who prefer a less flashy gaming experience with fewer distracting bells and whistles.

Donbet

You’re more likely to get the theme of Donbet from its name if you’ve seen movies like Goodfellas and The Godfather than if you haven’t, although that alone is a clue. Donbet is a casino with a mafia theme, and as such, it’s probably the most interesting of the Cosmobet sister sites to look at and play with. We’ve already said nice things about the aesthetic qualities of Cosmobet, but Donbet has it trumped on that front. The theme has been realised exceptionally well, with bespoke graphics and bonuses linked to the mafia concept.

Themes are all well and good, but should you really get excited about the idea of playing at Donbet when it’s based so much of its character on the mafia? You wouldn’t fancy your chances at a mafia-owned casino in real life, after all! In this instance, though, we don’t think Donbet is any less trustworthy than any of the casino brands it shares a platform with. That might be damning the site with faint praise, but it’s the best we can do for casinos with this licensing status.

Cosmobet Review 2026

Cosmobet made its grand debut in 2023 as part of the Santeda International B.V. portfolio and has operated in the UK without the backing of a UK Gambling Commission licence ever since its inception. Despite this – and despite the casino being illegal in the United Kingdom –  we’ve noted a growing enthusiasm for this casino in our market. Its homepage, bustling with dynamic banners and moving images, seems to be drawing increasing attention. This rising interest could be partly attributed to the soaring popularity of MyStake, the standout site among the Cosmobet sister sites. Could Cosmobet one day achieve a similar level of fame, or should players be cautious of this space-themed casino and its cavalier attitude to licensing? Let’s see.

Cosmobet Welcome Promotions

Rather than offering its players a single welcome promotion, Cosmobet gives its players three different ones to consider. The best one for you as an individual will depend on how you wish to engage with Cosmobet, but for most people, it will likely be the standard first deposit welcome bonus. That’s a 150% boost up to a maximum value of £500 on first deposits only, subject to a minimum deposit of £20. The wagering requirement that comes with the bonus cash is x30, which is low enough to be considered reasonable. Fifty free spins are thrown in with this bonus to sweeten the pot a little.

If you’re willing or able to use cryptocurrency instead of fiat currency to make your first deposit, you can claim an alternative promotion – a two hundred per cent first deposit boost up to a maximum of £1000. The minimum qualifying deposit is again set at the crypto equivalent of £20, but the wagering requirement goes up slightly to x35. Alternatively, you could claim the sports betting welcome promotion, which is another 150% matched first deposit boost up to a maximum value of £1000. However, the x15 wagering requirement that it comes with has to be considered high for a bonus of this kind.

Other Promotions

The warm welcome at Cosmobet carries on beyond the first deposit a new player makes. Second and third deposits are also matched at 100% up to a maximum of £500, with the same wagering requirements and minimum deposit stipulations as the regular first deposit bonus. Those boosted deposits are nice to have, but players who use crypto to make their deposits get a better deal. They receive twenty per cent cashback on all of their deposits on an ongoing basis, capped at £200 per deposit and provided without any wagering requirements attached. It’s a great offer, which makes it all the more of a shame that there’s no such cashback promotion available for those who don’t use crypto. For sports bettors, Cosmonet offers a free fourth bet for every three best placed with the site.

What are the Pros and Cons of Cosmobet Casino?

Pros: Cosmobet offers a very warm welcome to new players – doubly so if you’re using cryptocurrencies to do your gambling. It’s a sports betting paradise with dozens of sports-specific promotions and a wide range of sports betting opportunities. Casino fans aren’t forgotten, though, with more than one thousand slots to play and a massive live iGaming suite.

Cons: As nice as the top promotions at Cosmobet are, the best of them are reserved only for those who use cryptocurrency. If you don’t or can’t use crypto, you simply don’t get quite so good a deal. It’s especially noticeable when it comes to cashback, which is available on deposits to crypto bettors but not to anyone else. Withdrawals are slower than we’d like them to be, and at the end of the day, the casino doesn’t have a UK Gambling Commission licence.

Top Games at Cosmobet

The way that Cosmobet focuses its promotions so heavily on sports betting is a little odd when you think about the way the casino’s website is laid out. Sports betting isn’t extensively promoted on the Cosmobet homepage. Instead, you’ll find most of the premium real estate on the site’s landing page taken up by the top slots games that it offers. Unlike a lot of Curacao-based casinos, the Cosmobet sister sites are served by most of the top providers in the iGaming business, and so the likes of Sugar Rush and Wolf Gold are featured prominently. Other top slots at the casino include Rich Wilde and the Book of Dead, Gates of Olympus, and Wanted Dead or a Wild. These are all tried, trusted and much loved slots, and they’re always popular wherever they’re available.

Beneath the top slots on the Cosmobet homepage, players will find a selection of “mini games.” These include standard games like Keno and blackjack, but also oddities like Plinko, Teleport, Limbo and more. These aren’t your standard slots or games and they won’t be of interest to everybody, but they’re a break from the norm and serve as a reminder that Cosmobet reaches places that other online casinos can’t get to.

Withdrawal Processing & Support

Cosmobet shows a clear preference for cryptocurrency transactions, evidenced by the beginner’s guide to purchasing crypto featured on its payments page. The site specifically recommends using Coinbase for transactions and accepts a range of cryptocurrencies, including Bitcoin, Tether, and Ethereum, among others. For those who prefer traditional currency, Cosmobet also accommodates MiFinity and AstroPay e-wallets, as well as the usual Visa and Mastercard debit cards. Regardless of the payment method chosen, every withdrawal is subject to an estimated processing time of three working days. It’s important to note that withdrawals are not permitted if there are any remaining funds from your last deposit, which might be a point of inconvenience for some players.

Customer Services & Licensing

Route one for getting in touch with the customer support team at Cosmobet is to use the live chat facility, which the casino tours as being available all day, every day. If you don’t want to use live chat, you can instead send an email to support@cosmobet.com. We’re not sure how long or short the wait for replies to emails might be.

The casino’s licensing situation is unclear. We’ve verified that its operator, Santeda International B.V., holds a full licence with the Curacao Gaming Control Board. There’s no mention of this licence on the casino’s website, though. It’s possible that the licence applies to the Cosmobet sister sites, but not to Cosmobet itself. In any event, even if it did hold a CGCB licence, it would still be illegal in the UK.

Cosmobet – The Verdict

Cosmobet’s space theme makes it more interesting to look at than most of the casinos on this network. It’s a well-organised casino with some neat promotions for crypto players and a massive sportsbook. Overall, the range of slots and other casino games that Cosmobet comes stocked with is impressive. We’re always going to have massive concerns about casinos that accept UK-based players without having the necessary licence to do so, though, and so we have to remind you again that if you decide to take Cosmobet for a spin, you do so at risk and without regulatory protections. That being said, if it’s legal to play where you live and you like MyStake, you’ll probably find that you like Cosmobet, too.

What are players saying about Cosmobet Casino?

Here are our condensed / reader’s digest summaries of recent Cosmobet reviews from real players.

• 20-Mar-2025 by Alex:
  Had a deeply frustrating experience with Cosmobet. I won £1,950 from my deposit funds, but they cancelled the payout, saying I’d hit a bonus limit—even though I didn’t use a bonus. Each time I contacted support, they dodged my questions and kept demanding more documents. After repeatedly chasing, they blocked me from chat altogether. I’ve followed every rule and still got treated terribly. I’m now filing a complaint with the Curaçao eGaming board. If you value fair treatment and transparency, I’d recommend steering clear. – source: Trustpilot
• 19-Mar-2025 by Josh:
  Put in a tenner and played 10p spins, well over 100 of them, without a single bonus round. That says it all really. Absolute waste of money. I won’t be using this site again and I’d suggest others avoid it too. – source: Trustpilot

  Generally had a decent experience and withdrawals were straightforward. But as a frequent depositor, I’m disappointed by the lack of bonuses—barely got a welcome offer and only a few free spins now and then. As a VIP, I expected more appreciation. – source: Trustpilot

  A great alternative to the big-name sportsbooks. Been using Cosmobet for over a year now and never had a single problem with withdrawals. Good offers pop up now and then, and although the odds aren’t always the best, they’re close enough to keep me loyal. – source: Trustpilot
