What is Rainbet?
Rainbet is a crypto-first online casino and sportsbook. There's no fiat banking in most regions — you deposit and withdraw cryptocurrency, and in exchange you get the things crypto casinos do well: sign-up in under a minute, withdrawals that clear on-chain in minutes rather than days, and a lobby that mixes in-house provably fair games with thousands of third-party slots and live dealer tables.
Its bonus program is unusual too. Instead of a deposit-match welcome package with heavy wagering, Rainbet pays rakeback — a share of your net losses returned to your wallet daily as withdrawable cash. With promo code BOOST20 that share starts at 20% instead of the standard 5%.
What can you play at Rainbet?
Rainbet Originals
Plinko, Mines, Dice, Limbo, Crash and Keno — in-house games at 99% RTP, each round verifiable through the provably fair system.
Slots
Thousands of titles from major providers, from classic fruit machines to high-volatility bonus-buy slots, searchable by provider and feature.
Live Casino
Live blackjack, roulette, baccarat and game shows streamed with real dealers. Table limits cover casual stakes through high roller.
A full sportsbook runs alongside the casino — pre-match and live odds across major sports, settled in the same crypto wallet. Every wager, casino or sports, counts toward the daily rakeback calculation at full weight; nothing is excluded.
Deposits and withdrawals
Banking is pure crypto. In our test sessions, deposits were credited after standard network confirmations and withdrawals reached our wallets within minutes of approval — the practical speed depends mostly on the chain you pick.
| Currency | Deposits | Withdrawals | Notes |
|---|---|---|---|
| BTC Bitcoin | 1 confirmation | Minutes | Highest network fees of the list |
| ETH Ethereum | Fast | Minutes | Fees vary with network load |
| USDT Tether | Fast | Minutes | Stable value — no coin volatility while you play |
| LTC Litecoin | Fast | Minutes | Low fees, a solid default choice |
| DOGE / TRX and more | Fast | Minutes | Additional coins listed in the cashier |
No minimum deposit is tied to the promo code. KYC can be requested before large withdrawals — standard practice under a Curaçao licence.
The bonus program in one paragraph
Rakeback is the centrepiece: 20% of your daily net losses returned automatically with code BOOST20, no wagering attached, withdrawable immediately. The VIP ladder raises the base rate up to 25% at Diamond, and rotating promotions add free spins and race prizes on top. The full breakdown — every offer, every condition — lives on our promo codes page and in the bonus terms guide.
How do you sign up at Rainbet?
- 1
Open rainbet.com
Use our link and hit Register — the form is email, username, password. Under a minute.
- 2
Enter code BOOST20 in the referral field
The field is collapsed in the sign-up form and easy to miss. It must go in now — it can't be added after you've placed bets.
- 3
Confirm you're 18+
Accounts flagged as underage are voided along with any winnings, so the checkbox is not a formality.
- 4
Deposit any amount of crypto
Pick a coin in the cashier, send to the generated address, play once it confirms. No minimum tied to the code.
- 5
Check your rakeback rate
The dashboard should read 20%. From then on it accrues on every bet and pays out every 24 hours.
Is Rainbet safe to play at?
Rainbet operates under a Curaçao gaming licence. That's a real licence with real obligations — but a lighter-touch one: disputes are handled between player, operator and regulator, without the independent ombudsman schemes of MGA or UKGC jurisdictions. Two practical consequences follow.
- The provably fair system matters more. For the Originals, every round's outcome can be independently verified from seed hashes — you don't have to take fairness on trust for the in-house games.
- Jurisdiction rules are enforced at withdrawal. Playing from a restricted country through a VPN tends to surface at KYC, and winnings are voided at that point. Check availability before depositing, not after.
Our overall read: a legitimate, fast-paying crypto casino, provided you're comfortable with the trade-offs of a Curaçao licence and crypto-only banking.

Rainbet casino — frequently asked questions
Is Rainbet legit?
Yes — it's a licensed (Curaçao) crypto casino operating since 2022 with millions of registered accounts. In our test sessions deposits, gameplay and withdrawals worked as advertised. The licence is lighter-touch than MGA or UKGC, so play with that in mind.
Is this the official Rainbet website?
No. Rain-Bet.io is an independent review and bonus guide. The official casino is at rainbet.com — everything you claim through this site is activated there, under the operator's terms. We may earn a commission if you register through our links.
How fast are withdrawals really?
In our checks, crypto withdrawals cleared on-chain within minutes of approval. First withdrawals or large amounts can trigger KYC review, which adds time once per account.
What is the best promo code for Rainbet?
BOOST20, entered at registration — it sets daily rakeback to 20% with no wagering and no expiry. Full details on the promo codes page.
Can I play on mobile?
Yes — there's no native app, but the site runs as a fast web app on iOS and Android with the full lobby and bonus program. See the casino app guide.
Which countries are restricted?
The list is set by the operator and changes — it's published in the terms on the official site. If your country is on it, don't try to route around it with a VPN: it voids winnings at KYC.
Play responsibly. Gambling involves risk and should be treated as entertainment, not income. Set deposit limits, take breaks, and if gambling stops being fun, seek help at BeGambleAware.org or Gambling Therapy.
