Most write-ups of the Rainbet welcome offer lead with the cash figure. Enter RAKEBACK100 at registration and the package is a 250% deposit bonus worth up to $2,100, 60 free spins across your first three deposits, and a 20% rakeback boost covering your first 72 hours of play. The spins are the part people skim, yet they arrive on their own schedule, on a specific game, and with their own conditions attached. This piece looks only at that component and what it does and does not guarantee.
The welcome package is spread over your first three deposits: 100% on the first, 50% on the second, 100% on the third, with 20 free spins at each stage. That is where the headline 60 comes from. Nothing in the offer hands you all 60 up front. If you deposit once and stop, you get one tranche of 20 and leave the rest behind, along with the unclaimed part of the $2,100 ceiling. The full cash maximum and the full 60 spins both require completing all three qualifying deposits, and each deposit carries its own qualifying minimum, maximum and cap, which are listed on the promotions page rather than in the registration modal.
The free spins run on a Pragmatic Play title. You do not get to spread them across the thousands of slots in the lobby, and you cannot move them to the in-house provably fair originals such as Mines, Plinko or Limbo. Two figures decide what the batch is actually worth — the value of each spin and the cap on winnings from them — and both are shown at the moment the spins credit. Until then, any number you see quoted elsewhere is a guess. Check the amount displayed on the spins in your account before you use them.
Free spin winnings sit under the same wagering treatment as bonus funds. A 40x requirement is commonly quoted on bonus funds and free spin winnings, though the multiplier and the per-game weighting are the figures to read on the promotions page at opt-in rather than take from a review. While a bonus is active, a maximum bet applies, commonly cited as a small percentage of your deposit, and eligible slots exclude titles above 97.4% RTP. Hacksaw Gaming and Nolimit City games are named as ineligible. Those rules matter after the spins finish, because that is when you start clearing whatever the spin winnings carry.
Register at rainbet.com through the modal that opens over the homepage, using email, Google, Steam or a Web3 wallet.
Expand the promo, referral or affiliate code line — often hidden behind a "have a code?" toggle — and type RAKEBACK100 exactly, with no spaces. The field is only on the registration panel, never in the cashier, and the code cannot be attached later by support.
Confirm you are 18 or over, accept the terms and submit.
Open the promotions page and opt in to your chosen welcome bonus before you deposit. Betting first can forfeit it.
Deposit through the crypto cashier, then check the bonus balance, the first tranche of spins and your rakeback percentage once the transaction credits, usually within minutes of one blockchain confirmation.
There are two welcome paths: a wager-locked route and one that drips bonus into withdrawable balance as a percentage of wagers. The lower-wagering alternative covers only the first deposit, and the choice is effectively final once you deposit — so if the full 60 spins are the draw, work out which path keeps all three stages open before you send anything. The 20% rakeback boost runs independently, lasting 72 hours from the start of play, and rakeback boosts do not stack or queue.
