Rainbet Crypto Casino Review + Welcome Bonus 2025
Duelbits Crypto Casino Review + Welcome Bonus 2025
Rainbet crypto casino went live in 2023, and today offers thousands of slots, instant win, table, and live dealer games, including provably fair titles, plus sports and esports betting.
In this original CoinBets review, I’ll be opening an account, depositing real crypto, and checking out everything Rainbet.com has to offer. In particular, I’ll analyze the Rainbet welcome bonus, payment options, games portfolio, loyalty program, and overall user experience. And, as always, I’ll be betting with real crypto to get the most authentic player experience.
So, let’s find out if Rainbet crypto casino is worth signing up for…
License and Security
Before we get to the good stuff, let’s make sure Rainbet crypto casino has legit credentials.
Rainbet is operated by RBGAMING N.V., a company registered in Willemstad, Curacao. However, despite still stating “Rainbet is licensed and authorized by the Government of Curaçao and operates under the Master License of Gaming Services Provider, N.V. #365/JAZ” in the site’s footer, the platform now has an Anjouan license.
The site security certificate is valid, and the connection shows as “secure”.
Welcome Bonus
You can choose from 2 different Rainbet welcome offers, as follows:
40x Wager Locked:
- 1st Deposit: 100% bonus + 20 free spins
- 2nd Deposit: 50% bonus + 20 free spins
- 3rd Deposit: 100% bonus + 20 free spins
No Wager Locked:
- 1st Deposit: 100%, claimable as you bet at a rate of Wager Amount x 1% x 20% per bet.
For both options, the minimum deposit to qualify is $30 and the maximum deposit is $700. Some games are disabled when the promos are active, including all games with an RTP of 97.4% or higher. For the 40x Wager Locked option, the maximum bet while the promo is active is 2% of the deposit amount, and free spins are only valid on Sweet Bonanza from Pragmatic Play.
While the RainBet welcome bonus is fairly typical, it is nice to have a choice of two options. However, while the No Wager Locked bonus might sound like it offers good value, you’ll only unlock $0.20 for every $100 you bet, so, erm… yeah.
Opening a New Account
Getting up and running at Rainbet crypto casino is easy enough. Simply hit the blue “Register” button and then choose one of the following options:
Choose a username, enter your email address, choose a strong password, and then confirm you’re over 18 and agree with the Terms and Conditions. Then click “Create Account.”

Payments
Rainbet supports many of the most popular cryptocurrencies for deposits and withdrawals.
Crypto Deposits & Withdrawals:
To make a crypto deposit, navigate to your wallet and click “Deposit”. Then select the crypto and network (if applicable) you’d like to use. You’ll be provided with a deposit address as both an alphanumeric string and a QR code. The minimum deposit for each crypto will be displayed.
To withdraw crypto, go to your wallet and select “Withdraw”. Choose the appropriate cryptocurrency and network (if applicable), and enter your destination wallet address. Set how much you’d like to withdraw - you can enter it as a dollar or crypto amount. Next, select either “Standard” or “Priority” withdrawal - the fee will vary depending on the specifics of the transaction, but an estimated fee will be provided.
CoinBets.com Tip: Always double-check crypto wallet addresses after pasting them - you don’t want to fall victim to ‘PasteJacking’. This is when hackers exploit the copy-paste function to change wallet addresses to steal funds.
Duelbits also supports fiat options including Trustly, Neosurf, Revolut, and PayDo, plus via bank transfer and Duelbits gift cards. Simply select “Card Payments” and follow the prompts.
Game Selection
Like all the best crypto casinos, Rainbet enables you to purchase cryptocurrency without leaving the platform. In this case, it is via Moonpay, which accepts a range of fiat payment methods including Visa, Mastercard, G Pay, and Apple Pay. To make a purchase, just select “Buy Crypto”, then select the desired crypto and network, before clicking “Continue to Moonpay”. Then follow the prompts to complete your purchase.
Fiat Deposits and Withdrawals
Rainbet also supports limited fiat transactions. The options available to you will depend on your location. For example, if you are in Canada, Interac is available, or if you’re in Brazil, you can pay via Pix.
Game Selection
Rainbet crypto casino offers a few thousand casino games from around 30 providers. The exact numbers aren’t stated, but I’d estimate it to be around the 3,000 mark. The main problem with the games catalog is a lack of useful filters and categories. For example, while in the slots section, you can only search by title, or filter by providers, A-Z, new releases, or popularity. There is a random game filter, but you can’t filter by game feature or theme.
Slots
Unsurprisingly, Pragmatic Play slots dominate the line-up at Rainbet, with nearly 500 titles available. So, if you’re a fan of games like Sugar Rush, Zeus vs Hades, Sweet Bonanza 1000, and Gates of Olympus, you’re in luck here. There’s also a good showing from Spinomenal with over 450 titles, Play’n GO, with nearly 375 games, and Red Tiger with 305 slots. Of course, slots are also available from many other providers including NoLimit City, Endorphina, BGaming, VoltEnt (Wazdan), and many more.
If you believe you can never have enough paylines, you’ll be glad to know there are plenty of Megaways slots available here too. For example, there are Might of Freya Megaways and Revenge of Loki Megaways from Pragmatic Play, NFT Megaways from Red Tiger, and Jungle Spirit Megaways from NetEnt. However, there’s no filter, so you’ll need to use the search function to find them.
The same goes for jackpot slots. They are here, but there’s no filter for them, so you’ll need to search for “Jackpot” in the title. Unfortunately, if you’re looking for huge progressive jackpots like Mega Moolah, you won’t find them at Rainbet.
CoinBets Experience
Burning Sun: Hold the Jackpot (VoltEnt/Wazdan)
Righty, I couldn’t decide which slot to play first, so I used Rainbet’s “Random Game” feature - which is always a nice option to have available. It gave me Burning Sun: Hold the Jackpot - Easter Edition. Yep, there’s a space bunny and chick to make it, well, Eastery.
Set just above the surface of the sun, it is a fiery little slot with sticky symbols, a bonus game, a gamble feature, three risk options (the chili pepper symbols), and four jackpots; Mini ($20), Minor ($50), Major ($150), and Grand ($5,000). Now, my intention was to place 100 x $1 bets, at medium risk, and see how I fared. Would I crash and burn into the surface of the Sun, or make it back to Earth with a spaceship full of loot?
Well, I definitely crashed, but managed to walk away in profit. You see, in the 9th round, I triggered the bonus game and landed a nice little $48 win. Then, in round 12, the game crashed. Despite reloading, I couldn’t get it to work again. Not cool. But, at least my funds were safe, and after wagering just $12, I’d won $51, giving an actual RTP of 425% - not too bad at all, and much higher than the theoretical RTP of 96.19%.
CoinBets Experience
100 Zombies (Endorphina)
After my solar mishap, I decided to move on to a slot with an altogether different theme - specifically, zombies. Everyone loves a good zombie apocalypse, right? Well, 100 Zombies from Endorphina has mixed World War Z and the Walking Dead, before adding a dash of Resident Evil and Silent Hill - then cartoonifying the lot of it. The end result is an action-packed and visually impressive 5-reel, 4-row slot with 100 paylines, and a bonus game that can be triggered by 3 Scatters or purchased as a bonus buy for $28.
But, I hear you ask, what happened? Did I survive the ravenous hordes unscathed? Well, yes, I did. After betting $100, I’d won $173.75, giving a real RTP of 173.75% - compared to the official theoretical game RTP of 96%. Out of curiosity, after playing the 100 rounds, I purchased the “Bonus Pop” for $28 - which gives 10 bonus round spins. Unfortunately, it only gave me a win of $8.35 - not exactly worth it in this case! Still, the game itself was a lot of fun and I’ll definitely be coming back to it.
Crash & Instant Wins
If there’s one thing that drives me insane, it's when crypto casino operators don’t bother to add useful categories and filters. It makes browsing extremely frustrating. Case in point - Rainbet hasn’t felt the need to add a category for crash or other instant-win games. There are crash games, like Speed Crash from Hacksaw, Crash Duel X from SmartSoft, and Aviator from Spribe, along with scratch cards like Stack’em Scratch and Tiger Scratch from Hacksaw, but again, you’ll need to search.
Live Casino
RainBet’s live dealer offering is dominated by Evolution, with 99 games available. Besides that, there are just 31 titles from Pragmatic Play Live (though the filter actually says just “4” are available). Hardly the most extensive live casino I’ve seen, but still, not the worst. You’ll find live games in the Blackjack, Baccarat, Roulette, and Game Shows categories, or can browse them all under Live Casino - so they are at least better organized than the slots.
At the time of making this Rainbet casino review, the most popular live dealer games included Evolution’s Crazy Time, Lightning Roulette, and Bac Bo, and Pragmatic’s Mega Roulette and One Blackjack.
Table Games and Video Poker
While there aren’t many RNG (Random Number Generator) based table games available at Rainbet, they are relatively easy to find. The blackjack, baccarat, and roulette, can be accessed from the main navigation menu, and video poker can be found via searching. However, to put things in perspective, there are only 4 video poker games available - Hold’em Poker, High Hand Hold’em Poker, Russian Poker, and In Between Poker, all from OneTouch.
Bingo
The selection of video bingo and keno at Rainbet is equally disappointing. There are just 4 bingo and 4 keno titles available - the former being mostly from Play’n GO, and the latter from SmartSoft.
Provably Fair Games
Rainbet offers a modest selection of 7 in-house original provably fair games. These consist of Blackjack, Mines, Keno, Dice, Plinko, and Case Open - all of which use the usual client/server seed provably fair system - and the multiplayer Case Battles, which uses EOS blocks to ensure fairness. So, if you’re a Counter-Strike fan into skins and lootboxes, Rainbet has you covered.
If you’d like to learn more about provably fair gaming, you can check out the CoinBets Introduction to Provably Fair Gaming.
CoinBets Challenge: Plink High, Plinko Low
For the CoinBets Challenge, I decided to put Rainbet’s original provably fair Plinko to the test. Specifically, by betting $200 on the highest-risk settings, followed by $200 on the lowest-risk settings - both with 16 rows. So, the highest potential multiplier in the first part was a nice 1,000x, and in the second part just 16x. Each bet was set at $5, giving a potential max win of $5K - though with just a 0.002% chance of achieving that.
But, did I pull it off? Well, in a word, “no.” After the first 40 high-risk bets, I’d wagered $200 and returned just $116, equating to a rather poopy RTP of 58%. And, in the second 40 low-risk bets, I’d wagered $200 and returned $194, giving a more respectable RTP of 97%. What can I say? You play high-risk and you’ve got to expect to lose more often than not. It’s the price you pay for the chance of winning big.
Sportsbook
In addition to its crypto casino offering, Rainbet also boasts a fully loaded sportsbook. This offers standard and live betting on traditional sports like soccer, American football, baseball, boxing, tennis, ice hockey, and MMA. Esports betting is also available on disciplines including CS2, League of Legends, Dota 2, and Valorant.
Promotions
Although the “Promotions” page only contains details of the Rainbet casino welcome package, there are other offers for existing players. To find them, select “Challenges” from the menu. Obviously, these change frequently, but to give you an idea of what you can expect, here are some that were running at the time of writing:
Slot Challenges
- Starlight Princess 1000 - First to hit 1,000x with minimum bet of $0.60 wins $400
- Snoop Dogg Dollars - First to hit 10,000x with minimum bet of $0.50 wins $5,000
- Zeus vs Hades: Gods of War - First to hit 10,000x with minumum bet of $1 wins $4,000
- Bonanza Billion - First to hit 1,500x with minimum bet of $0.30 wins $400
- Dead, Dead or Deader - First to hit 2,000x with minumum bet of $3 wins $2,000
Wagering Races
- $10K weekly wagering race - First prize of $2,750
- $100K monthly wagering race - Top prize of $20,000
Raffle
- $20K Weekly Raffe - Get 1 free ticket for participating, plus earn an additional ticket for every $500 wagered. 50 tickets win $400 each.
VIP Club
The Rainbet loyalty scheme is structured around “Chest Keys.” There are 5 tiers; Bronze, Silver, Gold, Platinum, and Diamond. The keys are rewarded based on your wagering as follows:
- Bronze I - $10K to reach
- Silver I - $50K to reach
- Gold I - $100K to reach
- Gold II - $250K to reach
- Gold III - $500K to reach
- Platinum I - $700K to reach
- Platinum II - $1.3M to reach
- Platinum III - $2.5M to reach
- Platinum IV - $4M to reach
- Platinum V - $7M to reach
- Platinum VI - $10M to reach
- Diamond I - $15M to reach
- Diamond II - $50M to reach
- Diamond III - $100M to reach
- Diamond IV - $250M to reach
- Diamond V - $500M to reach
The keys unlock rewards including rakeback, daily bonuses, weekly bonuses, and monthly bonuses - with a “portion of your daily, weekly, and monthly bonuses spread out across the calendar”. Apparently, the specific rewards for each rank “depend on promotions the users are using.” Beyond that, it’s all a mystery here at Rainbet.
Player Support
As to be expected, Rainbet crypto casino provides player support via live chat and email (support@rainbet.com). There’s also an FAQ database that answers the most common questions.
Beyond that, Rainbet has a blog - but in all honesty, it’s clearly designed for SEO (search engine optimization) purposes, rather than to add real value for users. I mean, flippin’ heck, they haven’t even bothered adding images!
Rainbet’s social media presence is limited to Telegram, X (Twitter), and Instagram.
User Experience & Website Design
Meh, what can I say about Rainbet in terms of design? It’s yet another cookie-cutter casino - with a typeface and color scheme that looks suspiciously like Stake.com. Well, they do say imitation is the sincerest form of flattery!
Still, for the most part, everything seems to work well enough. The main issue I have with Rainbet is the annoying lack of categories and filters - it just makes browsing games such a chore. Ufff. Additionally, as is all too common with crypto casinos, there’s a distinct lack of responsible gambling resources. Yes, Rainbet does make it easier than most to request self-exclusion, and there is the usual blurb about safer gambling, but there are no easy-to-use tools to set wager, loss, or time limits.
In terms of language accessibility, Rainbet is only available in English and Portuguese.
Mobile apps
In common with most smaller crypto casinos, Rainbet doesn’t offer a dedicated mobile app for Android or iOS devices. However, the web-based platform is optimized to run on mobile browsers, so you can still enjoy the casino on your smartphone.
Overall Reputation
Right, so that’s what Rainbet offers in terms of product - but what about its reputation? Well, here’s what a few popular casino review platforms say:
| Platform | Overall Rating | Notes |
|---|---|---|
 | 3.6 Average | (based on 211 reviews) |
 | Overall: 8.6/10 | Safety Index: High |
 | Trust Score: 5.9/10 | |
 | Overall: 5.5/10 |
What can we make of this? Well, apart from Trustpilot, they are all affiliate sites - and as we all know, affiliate marketing sites aren’t exactly objective! So, do these ratings really mean much at all?

Rainbet
Okay, this is a tough one. After landing a very nice win on Lightning Storm Live, it’s tempting to be enthusiastic about CryptoLeo - after all, I had a lot of fun playing that.
Verdict
Okay, this is a tough one. After landing a very nice win on Lightning Storm Live, it’s tempting to be enthusiastic about CryptoLeo - after all, I had a lot of fun playing that. But, this is primarily a CryptoLeo casino review and not a review of an Evolution game. So, yes, some of the individual games are great, but CryptoLeo itself is disappointing.
There are multiple issues here. First, it’s horrible to use. Really, the categories, filters, and search facilities are frustrating, to say the least. Secondly, the full terms and conditions are not clear enough. Thirdly, it has exceptionally low withdrawal limits. Fourthly, player support leaves a lot to be desired. Fifthly, the casino straight-up lies about its mobile app. Oh, and sixthly (I’m not sure I’ve ever written that before!), let’s not forget trying to pass off third-party games as “CryptoLeo Originals.”
Also, I do wonder if the Premier League and LeoVegas would have something to say about CryptoLeo’s branding - which seems like a blatant attempt to capitalize on these two legitimate brands.
