21bets.io Sister Sites 2026

Jupi Casino

If you think about it for a moment, you can probably guess the theme of Jupi Casino without even visiting this casino’s website. To save you the effort, “Jupi” is short for “Jupiter,” the largest planet in our solar system, suggesting that Jupi Casino aims to be a truly massive iGaming site. In many ways, it lives up to this ambition. It seems to offer more slots and games from various providers than other 21bets.io sister sites, and it shares several features with Supacasi, which many players regard as the unofficial flagship of this casino platform. There isn’t much to choose between them, but they’re both fabulous casinos so long as you live in a part of the world where you can access them without breaking the law or putting yourself in a position where you have no regulatory support. UK players, we’re afraid that means no Jupi Casino for you.

Spinbookie

There was a time when Famagousta B.V. was exclusively interested in producing casino sites, but that’s no longer the case. 21bets.io, with its sports betting focus, is evidence of that, but 21bets.io wasn’t the first iGaming site launched by the operator with this focus. Some of the 21bets.io sister sites beat it to the punch, and none have done so with as much gusto as SpinBookie. Don’t worry if you’d still rather be playing slots, though – the “spin” in the name of the site is a hint that you’ll still be able to do that. The long and impressive list of bonuses at SpinBookie is likely to turn the head of many a prospective player even if the terms and conditions attached to those bonuses aren’t always favourable, and the size of the SpinBookie portfolio is monumental. The site could do better with payout times, though.

Luck of Spins

When you see a casino with “luck” in its name, you might expect an Irish theme, but that’s not the case with Luck of Spins. Instead, it’s all about the Wild West. The site brings this theme to life with impressive graphics, continuing the trend seen in other 21bets.io sister sites. One of the good things about Luck of Spins is its ongoing cashback offer, which means you’ll get some of your losses back even if you don’t win. However, the welcome bonus isn’t as appealing since it has a much higher wagering requirement compared to other casinos on the Famagousta B.V. platform. On a positive note, there’s also a sportsbook, making it more similar to 21bets.io than other sites in the network. Sports betting isn’t often the focus of the iGaming sites on this network, but you’ll still find the facility there more often than you won’t.

OhMyZino

Let’s talk about OhMyZino, which is a well-known Famagousta B.V. casino that finishes its impressive style of presentation with a cartoonish look. If the style feels familiar, you might have seen it on Simsino or perhaps Wink Bingo, which is a safe, UKGC-regulated option for those who like this kind of decor. All three use a Pop Art style, more influenced by Lichtenstein than Warhol, making the casinos feasts for the eyes. If Supacasi wasn’t already our top pick among the 21bets.io sister sites (and we promise we’re getting to that casino in a moment), OhMyZino would be a strong contender for that title. There’s not much to separate the two, but you could argue that OhMyZino has an advantage because it includes sports betting, which Supacasi doesn’t offer. So, if you’re after something like 21bets.io, OhMyZino might be your best bet. It’s much, much better than your average international casino.

Supacasi Casino

This lively, cat-themed casino with an oriental flair is widely regarded as the best bet among the 21bets.io sister sites. However, it’s quite different from 21bets.io as it’s focused on casino games rather than sports betting. Designed with a different purpose in mind, it gives players a significant amount of control over the promotions they can access and offers many ongoing rewards. The extensive range of casino games at Supacasi will likely please even the most experienced iGaming enthusiasts. However, not everything is perfect; the casino’s withdrawal process isn’t clearly explained, and the per-transaction limit is relatively low. If you’re a budget-conscious player who doesn’t mind waiting a bit for withdrawals, this shouldn’t be much of an issue. If, on the other hand, you’re a high-roller and you prefer your withdrawals to be with you in a matter of hours rather than days, Supacasi might be one to skip.

21bets.io Key Information

21bets.io Review 2026

First, a bit of housekeeping; we’re referring to this casino and betting site as 21bets.io so as not to create confusion with 21betscasino.com, which is UK-focused and owned by ProgressPlay Limited. This bright red site, on the other hand, belongs to Famagousta B.V. in Curacao, and launched in May 2022. Like a lot of the top sites on this increasingly popular international casino network, it offers a full casino, live casino and sports betting exchange, with sports betting being (just about) the main focus of the site. 21bets.io doesn’t have a theme, but it manages to be easy on the eye thanks to the operator’s usual high standards when it comes to design. How it plays is more important than how it looks, though, and you’ll know how well it plays by the end of this review.

21bets.io Welcome Offer

There are actually three welcome bonuses to choose from at 21bets.io, but we suspect that most people who join the site do so for the sports betting action. Those sports bettors can claim a 100% matched deposit up to a maximum value of £250 in return for a first deposit of £30 or more. The entire value of the bonus must be wagered x5 before anything can be withdrawn from it. While that’s higher than the average wagering requirement for sports betting bonuses, it’s not by such a degree that it’s really off-putting.

If you want to spin the reels of slots rather than predict the outcomes of sports, you can claim a 120% matched deposit bonus up to a maximum value of £600 on your first deposit. The qualifying deposit for this bonus is £30 again, but this time the wagering requirement is x45. That’s a high hurdle, and it will take both luck and effort to clear it. Players who prefer live dealer games can claim an alternative live casino welcome promotion of a 100% matched first deposit up to £200, with a minimum qualifying deposit of £25 and a wagering requirement of x35.

Ongoing Promotions

Most of the ongoing promotions at 21bets.io are seasonal or event-specific, and favour sports betting. If you visit the site during a major sporting event – let’s say the World Cup or Wimbledon – you’ll see an extensive range of promotions and bonuses focused on those events. There isn’t a VIP scheme to speak of, but there are still a few bonuses at 21bet.io that could offer long-term value. For football bettors, bets will be paid out early if the team you’ve backed goes two goals up during normal time. On the other hand, if the game ends as a 0-0 bore draw, you’ll get your stake back.

Over on the casino side of 21bets.io, players can claim a 100% matched deposit up to £500 every Friday, with a minimum deposit of £30 (again) and a harsher wagering requirement of x50. A similar bonus is available every Wednesday for live casino players, with a 30% boost up to £500 available based on a £30 minimum deposit and an x35 wagering requirement. 5% cashback is available on weekends, and players who use crypto can claim a 150% boost once per day on all deposits worth between £25 and £1000. An x45 wagering requirement is in place for that one.

What are the Pros and Cons of 21bets.io? 

Pros: The list of activities here is long, with every major sport covered and great casino games drawn from a wide panel of providers. The bonuses are numerous, and some of them offer decent value with a realistic prospect of making a return.

Cons: While the terms of some of the bonuses are OK, others come with playthrough requirements that are too high to be considered reasonable or fair. Given that the only way to make withdrawals from 21bets.io is via crypto (which is itself a problem), it’s a surprise to find out that the turnaround time is three business days. Crypto withdrawals really ought to be instant.

Top Games at 21bets.io

The list of options and categories across the top of the 21bets.io homepage goes sports, exchange, live sports (quite why that needs its own category is unclear), casino, live casino and “live spins.” A couple of those categories are unnecessary, but it’s obvious that there’s plenty to do at this iGaming site. Football gets more coverage than any of the other sports in the 21bets.io sportsbook, but surprisingly, online slots get more space on the casino’s homepage than any sport. Even more surprising is the fact that while the casino has a basic iGaming licence, it’s missing quite a few big-name providers from its archives.,

The top slots at the time of our visit to 21bets.io to write this review were Fortune Rabbit by PGSOFT, Zeus the Thunderer by Mascot, and Book of Conquistador by Endorphina. All three providers are capable of creating fantastic slots games, but they’re not on the same level as the likes of Playson, Pragmatic Play or NetEnt. Slots by Tom Horn Gaming and Yggrasil can be found further down the homepage (Raptore Double X and Crystal Fruits Bonanza, for example), so we don’t know why they haven’t been afforded a greater share of the spotlight.

Withdrawal Processing and Support

Towards the bottom of the 21bets.io homepage, you’ll find a scrolling list of payment providers. Almost every method you can think of is covered, and because of that, you’d be entitled to expect 21bets.io to be able to pay you however you wish to be paid. If only that were the case. The list is misleading – while all of the named methods are fine for deposits, 21bets.io can only pay out in cryptocurrencies, from Bitcoin Cash to USDT. To make matters worse, it takes the site three days to get money to you. Given that it’s effectively forcing you to use crypto, the least it could do is ensure that transactions are swift.

Customer Support and Licensing

Live chat support is available from 9am to 1am every day at 21bets.io, which is good news for everybody other than night owls. If you’re a night owl yourself – or if you just don’t want to use live chat – you can email the support team at support@21bets.io. Famagousta B.V. holds a Certificate of Good Standing (a licence by any other name) from the Kahnawake Gaming Commission of Canada. It isn’t the most comprehensive or respected licence in the iGaming world, but it nevertheless covers 21bets.io and all of the 21bets.io sister sites.

21bets.io – The Verdict

The likes of OhMyZino and Supacasi Casino set the bar pretty high for the other casinos and betting sites on the Famagousta B.V. platform, and not all of them can reach it. While it has positive points, 21bets.io falls short of the standard by some distance. The terms and conditions attached to the bonuses here simply aren’t as attractive as those attached to the other casinos on the network, and the lack of diversity in the providers that supply the 21bets.io portfolio means that the range is a little limited. It isn’t a bad casino by any means, but you’ll find better casinos and betting sites by the same operator.
