About Rainbet
What is Rainbet?
Rainbet is a crypto casino and sportsbook launched in 2023. It accepts BTC, ETH, USDT, LTC and other coins, and is known for a large slot library, in-house originals and a rakeback-based VIP programme.
Rainbet works like most crypto casinos: you sign up with an email, deposit crypto, and withdraw to your own wallet. Identity checks are requested in specific cases rather than at signup.

How to claim
Four steps, about two minutes
Copy the promo code from the coupon above.
Open the casino through the button on this page. The link carries our referral, so the code is pre-filled where the casino supports it.

Where is Rainbet available?
Rainbet publishes a list of restricted countries in its terms of service. Check it before you sign up. If your country is on the list, don't use a VPN to get around it: the casino can close the account and keep the balance.
Rakeback, explained
What rakeback pays on a real session
Rakeback returns part of the house edge on every bet you place, win or lose. It is credited as real balance, so there is nothing to wager through. The example shows a one-hour session at a typical rate; your rate at Rainbet depends on the code and your VIP level.
Rakeback is paid on the edge, not on the stake. A 10% rate on a game with a 1% edge returns 0.1% of total turnover.
Is the Rainbet promo code worth it?
BOOST20 bundles three things: a deposit package worth up to $2,100, 60 free spins and a 20% rakeback boost for 72 hours. Our data lists the wagering as '40× or none', meaning some parts carry 40× and some carry nothing, so the value depends on which part you are clearing.
Here is what 40× costs. If a part of the package gives you a $100 bonus with 40× on the bonus, you need $4,000 in bets. At a 1% edge that is about $40 of expected loss; at 4% it is $160. If the 40× applies to deposit plus bonus on a $100 deposit, double both figures. The break-even edge for 40× on the bonus alone is 2.5%: above that, wagering costs more than the bonus is worth.
The 72-hour boost is a smaller lever. If you wager $2,000 on 1%-edge games in those three days, the house edge on that play is $20, and every 10 percentage points of rakeback on it is worth $2. Rainbet doesn't publish its base rate, so check your VIP page to see what the boost adds to.
The verdict: worth it if you check which parts of the package have no wagering and play the rest on low-edge games. Read the BOOST20 terms on Rainbet before depositing, and run the numbers in the wagering calculator.
Rainbet offer terms at a glance
From our last manual check of the BOOST20 offer.
| Term | Rainbet |
|---|---|
| Code | BOOST20 |
| Offer | Up to $2,100 + 60 free spins + 20% rakeback boost |
| Rakeback | +20% boost for 72 hours (base rate not published) |
| Wagering | 40× or none, depending on the part |
| Min deposit | $10 |
| KYC | None for crypto |
| Coins | BTC, ETH, USDT, LTC, DOGE |
| Licence | Curaçao |
| Online since | 2023 |
| Checked | 16 Sep 2026 |
The two terms that matter most are the split wagering and the 72-hour clock. 'Up to $2,100' is a ceiling across the package, and each part has its own conditions, so find out which parts are wager-free before you plan your first deposits. The rakeback boost runs for 72 hours from activation, so it only helps if you already planned to play in that window. Don't bet more just to use it.

Rainbet promo code for existing users
BOOST20 is entered at signup and can't be added to an account that already exists. The welcome package, spins and 72-hour boost are for new accounts only.
Existing Rainbet players get value from the VIP programme, where rakeback grows with your level, and from the weekly raffles and races Rainbet runs. Check the VIP and promotions sections of your account for what is live now.
If someone offers you a 'Rainbet code for existing users' that adds cash to your balance, be sceptical. Rainbet publishes its own promotions on its site.
BOOST20 vs other codes on this site
Rainbet's package suits players who want a lot of bonus value up front and some spins on top. Two other codes compete for the same player.
The Shuffle promo code SHFLVIP is a single 200% match up to $1,000 with a clear 35× on deposit plus bonus. It is easier to model if you like knowing the full requirement in advance. The Coins.Game promo code is the pick if spins matter most to you, with no wagering on spin winnings.
If you'd rather skip bonus wagering altogether, a rakeback code such as Thrill's maxrakeback returns part of every bet with no rollover.
Rainbet code not working? Fixes
BOOST20 works in whichever code field Rainbet shows at signup. If something goes wrong, start here.
| Problem | What to do |
|---|---|
| Code field missing | Use the button on this page, which carries the code in the link. Otherwise look for a promo, referral or affiliate code field on the signup form. |
| Code rejected | Enter BOOST20 with no spaces. Pasting avoids mix-ups between the letter O and zero. |
| Signed up without BOOST20 | The code can't be added later. Contact Rainbet support to ask. |
| Package not showing after deposit | Check the deposit met the $10 minimum and the coin was credited. Then check the bonus section of your account before contacting support. |
| Free spins not found | Look in the bonus or rewards area of your account. Spins are usually tied to a specific slot. |
| Country on the restricted list | Don't use a VPN. Rainbet can close the account and keep the balance. |
Rainbet affiliate code
'Rainbet affiliate code' gets hundreds of searches a month. On Rainbet, the affiliate code, referral code and promo code are the same thing: one field, one code. BOOST20 is the code that field takes.
If you are looking for a way to earn as an affiliate yourself, that is a separate programme run by Rainbet, with its own sign-up. Entering a code at registration doesn't make you an affiliate.
Rainbet promo code 2026: does BOOST20 expire?
Searches often add a year to the code. BOOST20 isn't a dated code; it stays the same until Rainbet changes the offer. We recheck it by hand, and the date in the table above shows the last check.
If BOOST20 is rejected and you typed it correctly, tell us. Codes listed with a different year on other sites are often old.
