Rainbet markets its welcome deal as up to 1 BTC, but the terms CasinoGuru recorded are written in dollars: three deposit matches, each capped at 700 USD, each with 20 spins on Sweet Bonanza. The rule that shapes everything else is unusual. Your maximum bet while the bonus is active is 2% of the deposit that unlocked it, not a fixed euro or dollar amount. Combine that with 40x wagering on deposit plus bonus and a neat bit of arithmetic falls out, which we explain below. We also cover the crypto-only cashier, the short verification deadline CasinoGuru flags as unfair, and the self-exclusion complaints on record.
Three 700 USD caps instead of one bitcoin
Add the caps and you reach 2,100 USD plus 60 spins. That does not connect to the 1 BTC headline, which depends on the bitcoin price and may reflect a different promotion. Our view is to plan around the dollar terms, since those are the ones with written conditions attached. The 60 spins are worth 6 USD at face value, a small extra rather than a reason to sign up.
- Deposit 1: 100% up to 700 USD + 20 spins.
- Deposit 2: 50% up to 700 USD + 20 spins.
- Deposit 3: 100% up to 700 USD + 20 spins.
- Each needs at least 30 USD; spins are worth 0.10 USD each on Sweet Bonanza.
- Wagering: 40x the deposit plus the bonus. Max bet: 2% of the qualifying deposit.
The 4,000-spin floor built into a percentage bet cap
Here is the quirk. On a 100% step, your balance is twice your deposit, and 40x of that is 80 times the deposit. Your largest allowed bet is 2% of the deposit. Divide one by the other and you get 4,000. Whether you deposit 30 USD or 700 USD, clearing a 100% step takes at least 4,000 bets at the maximum stake.
On the 50% second step the floor is a little lower. Balance is 1.5 times the deposit, rollover 60 times the deposit, and 60 divided by 0.02 is 3,000 bets. A bigger deposit does not get you through faster; it only raises the stake size.
A 100 USD first deposit in real figures
Deposit 100 USD and you receive 100 USD of bonus. The target is 200 x 40 = 8,000 USD. Your stake can be no more than 2 USD, so you face at least 4,000 spins. Over 8,000 USD of play at a 96% return, the expected loss is about 320 USD, which is more than the entire 200 USD balance. In most sessions the bonus will run out before the rollover does.
Max out the first step instead with 700 USD and the target becomes 56,000 USD at stakes up to 14 USD. The spin count does not change, but the swings get much larger. Think hard before putting four figures into a bonus with these terms.
Paying in with a card, cashing out in crypto
Rainbet takes Visa, Mastercard, Apple Pay, Google Pay, PayPal and MoonPay for deposits, but the records show card and bank withdrawals are not offered. Payouts go out in crypto such as Bitcoin, Ethereum, Tether or Litecoin, or through Interac and Pix. Crypto withdrawals land within an hour after a pending stage of up to 24 hours, and players on CasinoGuru repeatedly mention fast payouts. One reviewer also notes a small withdrawal fee, so check the cashier before you request one.
If you have never held crypto, set up a wallet before you deposit. Learning that step after a win, with a deadline looming, is how mistakes happen.
The 72-hour KYC clause and the complaint record
CasinoGuru rates Rainbet's terms as unfair because of an unreasonably short window, 72 hours, for supplying verification documents. Miss it and your withdrawal could be held up or your account restricted. Have ID and proof of address ready before you claim.
Several complaints on CasinoGuru involve self-exclusion. One player said the self-exclusion tool failed and allowed 980.79 USD of further play during a cooling period; another reopened a closed account despite a gambling problem. Self-exclusion is the only responsible gambling tool listed for Rainbet, with no deposit, loss or time limits. If you need limits, use your bank's gambling block or a third-party blocker as well.
Licence and ratings in brief
Rainbet is run by RBGAMING N.V., launched in 2023, and is licensed in Anjouan, Comoros (ALSI-152406029-FI2). CasinoGuru gives it 6.5, Above average, and estimates very large revenues. AskGamblers also scores it 6.5, while Trustpilot shows 2.1 stars across 615 reviews.
Anjouan is one of the lighter licensing regimes, with fewer routes for players to escalate a dispute than a European regulator would offer. That does not make Rainbet unsafe by itself, and CasinoGuru found it on no blacklists. It does mean that the bonus terms and your own records are your main protection. Players who leave reviews on CasinoGuru tend to praise the speed of verification and payouts, and one mentions rakeback as a perk, though no rakeback rate is available to quote. Support is in English only.
