Rainbet Sister Sites 2026

We strongly suspect that the “RB” in “RBGaming N.V.” stands for “Rainbet.” Whenever there’s such a strong connection of names between a casino and its operator, the casino tends to be the only one on the operator’s platform. There are exceptions to this rule, but Rainbet isn’t one of them – as of the time of writing it stands alone, with no Rainbet sister sites available. We operate a live service here at Sister Site, so if anything ever changes on that front, we’ll be straight back here to provide updates and give you the lowdown on all the best Rainbet sister sites. In the meantime, if you’ve had your fun with your current casino of choice and you’re on the hunt for something new, we recommend you take a look at our new casinos page. Everything you’ll find there is hot off the press.

Rainbet Casino Review 2026

Rainbet claims to be the best crypto casino in the world, a claim you’ll see repeated at almost every crypto casino you come across. No longer a novelty, the cryptocurrency casino market is bloated and saturated, with far too many casinos competing for attention from a small, niche audience. Rainbet, however, has fared better than most of them. It’s big, it’s busy, and it regularly attracts positive reviews on review websites like Trustpilot. In this review, we’ll be trying to find out what all the fuss is about.

Rainbet Casino Welcome Offers

The homepage of Rainbet couldn’t be any clearer about the casino’s welcome promotion, which is given £2100 in deposit bonuses and sixty free spins. The reality of the offer isn’t quite so simple. The promotion divides into three, with a 100% match and twenty free spins on deposit one, 50% and twenty spins on deposit two, and back up to 100% and the final twenty spins on deposit three. The maximum bonus per deposit is £700, thus arriving at the figure of £2100. The promotion comes with an x40 wagering requirement. That’s very slightly over the industry average (x35), but not by so much that anyone should lose any sleep over it.

There’s an alternative welcome promotion at Rainbet which is advertised as being wager-free (or “no wager locked,” as the casino puts it), but we don’t think it actually is. It’s a one-off 100% matched deposit of up to £700, but it comes out in increments. Players unlock an amount equal to one per cent of their wager multiplied by twenty per cent each time they place a bet. As an example, if you wager £100, you’d unlock 20p. That’s insanely complicated, and we’re generally not fans of promotions that leave us reaching for a calculator to work out their terms. For both versions of the welcome promotion, slots with RTP rates of 97.4% or higher don’t count for wagering.

Ongoing Promotions

We know that there are ongoing promotions at Rainbet in the shape of its Rewards scheme, but we can’t make head nor tail of it. Check this descriptive text out for size:- “Free chest keys rewarded as you wager, key given is same as current rank.” Confused? How about “Bonus chests returned from house edge.” These nonsense phrases are the only text on the Rewards page, the rest of which is taken up by pictures of keys and treasure chests. Towards the bottom of the page, we’re told that “a portion” of our daily, weekly, and monthly bonuses will be spread across a reward calendar, and we should come back to claim the rewards on the days indicated. It’s all as clear as mud, and there’s no way of knowing if there’s anything worth having in the scheme or not.

What are the Pros and Cons of Rainbet Casino?

Pros: Rainbet has a happy player base. We can see that from the multiple positive reviews of the casino on the Trustpilot website. It’s well-supplied, with more than 2500 slots and offers a few (basic) original games. While it’s a crypto-focused casino, you can also play and withdraw using fiat currency if you’d rather.

Cons: The bonuses at Rainbet are impenetrable. The general welcome promotion is fine, but the terms of the supposedly wager-free welcome bonus are baffling, and we defy anyone to make sense of the reward program. While the casino holds a licence with authorities in Anjouan, this (weak) licence doesn’t grant Rainbet permission to operate in regulated territories like the UK, which is why players from there can’t sign up.

Top Games at Rainbet Casino

There might be over 2500 slots here, but you might not be able to access all of them depending on where you live. We found several big-name providers were blocked in the UK, although the casino as a whole is also blocked from the UK from a legal perspective. The most popular (or “recommended”) of those slots are Cloud Princess, RIP City, and Le Pharaoh, all of which come from Hacksaw Gaming. Big Bass Vegas Double Down Deluxe (we’re begging for someone to end this series now) by Pragmatic Play is also a recommended slots game, as is the charmingly titled San Quentin 2: Death Row by NoLimit City.

The Rainbet “originals,” which are also promoted heavily on the casino’s homepage, are VS Case Battle, Case Unboxing, Dice, Plink, Mines, and Keno. While they’re stamped with the Rainbet logo, the chances are that you’ll have played games almost identical to these elsewhere. Rainbet also has a dedicated area for live game shows, including Crazy Time, Lightning Roulette, Monopoly, Football Studio, and Funky Time (plus many more), and also has all the usual traditional casino staples in its general live casino section. To finish off, Rainbet offers a full programme of sports betting and e-sports betting, including CS2, League of Legends, Dota 2 and Valorant, alongside a short list of real-world sports that includes real and American football, baseball, boxing, tennis, ice hockey, MMA, and basketball.

Withdrawal Processing and Support

We’re not given as much information about the way that Rainbet processes payments as we should be. The homepage makes clear that the casino prefers cryptocurrencies (Bitcoin, Litecoin, Ethereum, Tether, Dogecoin, and more) and will process withdrawals faster to crypto wallets, but that Interac, Google Pay, Apple Pay, and debit cards are also welcome. However, we’re not given precise timescales for any of the listed methods – not even the “fast” crypto withdrawals. The full terms and conditions of Rainbet spend quite a lot of time talking about the fact that the casino can provide withdrawals in Runescape Gold, which is a currency from a video game. That’s more than a little strange.

Customer Support and Licensing

The chat service that Rainbet offers isn’t “live” in the truest sense of the word, but an agent usually replies within sixty seconds or less when a message has been sent, so it’s the next best thing. If nobody gets back to you, email support@rainbet.com. Formerly licensed in Curacao, where its operator is based, Rainbet is now covered by an Internet Gaming Licence issued by the State of Anjouan. This is a relatively new and lightly regarded license, but it’s still better than having no license at all. While the licence doesn’t grant the casino the legal right to operate in the United Kingdom, it’s theoretically valid for any Rainbet sister sites that may appear in the future.

Rainbet – The Verdict

There’s something a little off about Rainbet. The wager-free welcome bonus isn’t actually wager-free, and the mechanics of its reward scheme are a mystery. It doesn’t give precise terms for its banking processes but then spends a disproportionate amount of time talking about its ability to process the token currency of the Runescape video games. Taken as a package, we don’t think the casino holds together particularly well. Perhaps we’re missing the point somewhere, though – as you can see from the player reviews below, plenty of people love it.

What are players saying about Rainbet Casino?

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

• 23-Jul-2025 by Khashaiar:
  This site has been brilliant so far. I’ve used both the live casino and the sportsbook and won about £990, of which I cashed out £875. The withdrawal came through Interac in under 20 minutes, exactly as promised by the support agent Eva. She was quick to reply and gave a clear and honest estimate. It might be a newer casino, but they’ve treated me well so far, and I’ve had no complaints. – source: Trustpilot
• 23-Jul-2025 by Jarryd:
  Total scam. I lost roughly £3,900 before finally hitting what should have been a big win worth over £19,500. But they only sent me about £195 in crypto and insisted that was the full amount. Their support team kept repeating that the full winnings had been paid. Steer well clear and use a proper casino instead. – source: Trustpilot
• 23-Jul-2025 by Lou:
  Avoid at all costs. After making a deposit, my bank locked all my cards for suspicious activity. I was ahead by around £62 and got a £97 bonus too, which I’d more than played through. Despite only using what should’ve been my own winnings at that point, I wasn’t allowed to withdraw. Customer support was no help either. – source: Trustpilot
• 22-Jul-2025 by Justin:
  I caught them fiddling with game outcomes. I opened a £310 Dragon Lore case and it landed on the rarest possible item, only for it to switch to a £0.78 item right after the spin. It’s completely fixed. They let you win on small bets, but the moment you raise the stakes, they start manipulating outcomes. Nothing you can do about it except warn others. – source: Trustpilot
• 17-Jul-2025 by Robert:
  As soon as I deposited a decent amount, the site turned brutal. I lost 15 times in a row on a 50/50 dice game. Once they’ve got your money, it feels like the odds magically change. Wouldn’t trust it again. – source: Trustpilot
• 16-Jul-2025 by Martin:
  This site’s no good for slot players. I wagered around £125 in small bets and didn’t get a single bonus round. After four deposits, the most I was ever up by was a pound. Their so-called rakeback isn’t much use either, and their gimmicky calendar system feels designed to keep you hooked. Not worth it. – source: Trustpilot
• 15-Jul-2025 by Andrew:
  Total waste of time. Every time I increased my bet, I lost. The whole thing felt rigged from the start. Don’t bother with this one unless you like frustration. – source: Trustpilot
• 15-Jul-2025 by Keith:
  I’ve really enjoyed playing on Rainbet. I’ve had a few decent wins and the return-to-player rate actually feels fair. Big shoutout to Eva from support who’s always been helpful, especially with sorting out my weekly reward questions. Top experience so far. – source: Trustpilot
• 12-Jul-2025 by Whitney:
  Everything’s been smooth so far. Deposits are instant, but the highlight has been how fast support gets back to you. I had a small issue with a bonus and Ruby sorted it within 10 minutes. The site’s layout is also easy to use. Thumbs up from me. – source: Trustpilot
• 09-Jul-2025 by Yokeris:
  If you win more than a couple of times, they’ll limit your account. That’s exactly what happened to me after two weeks. Don’t bother unless you like getting shut down the moment you do well. – source: Trustpilot
