The code RAKEBACK100 has to be typed into the registration panel at the moment you create your Rainbet account. It cannot be attached afterwards, and support cannot retro-fit it. That one-way door makes the minutes before signup the only sensible time to run your checks. The offer attached to the code is a 250% deposit bonus up to $2,100, 60 free spins spread across your first three deposits, and a 20% rakeback boost for your first 72 hours of play.
Work through the points below before you register, and again before you send any crypto.
Age. You must be 18 or over, or higher where local law requires it. Registration includes a tick box confirming this.
Country. Rainbet is not available in some countries, including the United States, and geographic restrictions also apply to the bonus itself. Confirm both your access to the site and your eligibility for the welcome offer.
Identity documents. Signup is no-KYC, but documents may be requested later, typically around larger withdrawals. If you would not be able to supply them, that matters more at withdrawal time than at deposit time.
The registration modal is short, but the promotions page behind it carries the detail. Before depositing, read:
The per-deposit structure. The welcome package runs across three deposits: 100% on the first, 50% on the second, 100% on the third, with 20 free spins per stage. The full $2,100 and all 60 spins require completing all three qualifying deposits.
Qualifying minimums and maximums. Each of the three deposits has its own minimum, maximum and cap. The exact figures are not stated here; read them on the promotions page.
The wagering requirement. A 40x requirement on bonus funds and free spin winnings is commonly quoted, but the figure and the per-game weighting are shown on the promotions page at opt-in. Treat the on-site number as the authoritative one.
Game exclusions. Slots above 97.4% RTP are excluded, and Hacksaw Gaming and Nolimit City titles are named as ineligible. The current excluded list lives on the promotions page.
Maximum bet while a bonus is active. This is commonly cited as a small percentage of your deposit. Check the exact cap before you spin.
There are two welcome routes: a wager-locked route, or one that drips bonus into your withdrawable balance as a percentage of your wagers. Cashout caps differ between them, and the lower-wagering alternative covers only the first deposit. The choice is effectively final once you deposit, so decide before you send funds, not after.
Also note that the welcome bonus is opt-in on the promotions page before depositing. Betting first can forfeit it.
If the full $2,100 is taken at a 40x requirement, that is $84,000 of turnover. At an estimated house edge of around 2.6%, expected loss over that turnover is roughly $2,100. Run that figure against what you actually intend to stake before deciding the package suits you.
The 20% rakeback boost is a separate matter. Rakeback accrues on all wagers, is claimable at short intervals and is paid win or lose, and loyalty rewards including rakeback have no wagering requirement and land as ordinary balance. The boost lasts 72 hours from the start of play. Boosts do not stack or queue, so only the highest active percentage applies.
