Rainbet and Mostbet are often shortlisted together. Below we compare them on what decides whether a casino is worth your deposit: safety, bonus terms, payments, games and what players report.
Safety and licensing: Rainbet vs Mostbet
Rainbet and Mostbet are almost level on safety: CasinoGuru gives Rainbet a Safety Index of 6.5/10 and Mostbet 6.7/10.
Rainbet is licensed by Anjouan Offshore Finance Authority, while Mostbet holds a license from Curaçao Gaming Authority. Both are offshore-style licenses, so the casino's own track record matters more than the license itself.
CasinoGuru lists 3 player complaints against Rainbet and 8 against Mostbet; bigger casinos naturally collect more, so read the number together with the Safety Index.
Mostbet has terms rated fair, while Rainbet's are rated unfair.
Bonuses and wagering
Rainbet offers new players up to 1 BTC Welcome Bonus. Mostbet offers 125% up to 400 EUR + 250 Free Spins.
The headline numbers matter less than wagering: Rainbet asks for 40x against 60x at Mostbet. On a €100 bonus that is €4000 versus €6000 in bets before you can withdraw.
Payments and payout speed
Rainbet lists 19 deposit methods (11 of them crypto) and Mostbet lists 55 (13 crypto). 16 methods work at both. They include Interac, Pix, Bitcoin and Ethereum.
Only Rainbet takes Cardano, MoonPay and PayPal. Only Mostbet takes Paysafecard, Perfect Money, Bitcoin Cash and Dash. If you already use one of these, that alone may decide it.
Rainbet pays crypto and e-wallet withdrawals faster (0-1 hours) than Mostbet (0-72 hours). Card and bank withdrawals take longer at both.

We could not confirm 24/7 live chat at either casino, so check support hours before you deposit.
Ownership and track record
Rainbet is run by RBGAMING N.V. and has been operating since 2023. Mostbet is run by Bizbon N.V. and has been operating since 2009. Mostbet has the longer track record, which usually means more complaints handled and more published payout history to judge by.
Responsible gambling tools
Rainbet offers 1 of the 10 responsible gambling tools we check (self-exclusion). Mostbet offers 2 of the 10 responsible gambling tools we check (self-exclusion, self-assessment test).
Deposit limits and self-exclusion are the two tools worth having before you play anywhere.
What players say
On Trustpilot Rainbet scores 2.1/5 (615 reviews) and Mostbet 2.5/5 (4,873 reviews). Casino reviews skew negative because unhappy players post more, so this counts for only 15% of our CasiScore rating.
