How to use the code on Rainbet
- 1Open Rainbet and click Register.
- 2Fill in your email, username and password.
- 3Open the field marked Referral Code (optional) and type BETARO.
- 4Check the code is still there, then finish creating your account.
- 5Make your first deposit of at least $30. The bonus and free spins are added to that deposit.
Sign up through the buttons on this page and the code is added for you, but check it's in the box before you finish. The code field is folded away under the state box, so it's easy to miss. If you already have an account, the code won't work on it. Rainbet ties every account to the code used at sign-up.

Referral code or promo code?
You'll see it called an affiliate code or a promo code on other sites, but there's only one box on Rainbet's sign-up form, labelled Referral Code. Whatever it's called, that's where it goes, and each account can only use one.
Typed once, in the Referral Code box. It sets your welcome offer and can't be changed later.
Rainbet gives every player one under Account, then Affiliates. Friends who join with it earn you a share of the house edge on their bets.
What the bonus is really worth
A 250% match sounds big, so it helps to see what it takes to turn it into cash. With 40x wagering on the bonus and a 2% max bet, every deposit size works out to at least 5,000 spins before you can withdraw it.
| Deposit | Bonus | To wager | Max bet | Spins | Avg. cost |
|---|---|---|---|---|---|
| $30 | $75 | $3,000 | $0.60 | 5,000 | $120 |
| $100 | $250 | $10,000 | $2.00 | 5,000 | $400 |
| $300 | $750 | $30,000 | $6.00 | 5,000 | $1,200 |
| $700 | $1,750 | $70,000 | $14.00 | 5,000 | $2,800 |
The last column is what that much wagering costs on average on a slot with a 96% RTP. It's more than the bonus at every deposit size, which is why most bonuses get lost along the way. Treat the bonus as extra playtime, not as money you're likely to withdraw.
There is an upside if you play a lot anyway. Clearing the full $1,750 bonus means $70,000 of wagering, which on its own takes a new account to Silver III in the Rainbet VIP program.
The 60 free spins: how Sweet Bonanza actually pays
The free spins land on Sweet Bonanza. We tracked 289,686 real-money bets on it across the casinos we follow over the last 30 days, and this is how they paid out.
- Less than the stake61.7%
- 1x to 2x13.6%
- 2x to 10x21.4%
- 10x to 100x2.8%
- 100x or more0.6%
- paid back the stake or more
- 38%
- paid double the stake or better
- 1 in 4
- paid 100x or more
- 1 in 165
- bets paid 1,000x or more, out of 289,686
- 2
So 60 spins will usually return a handful of small wins. A big hit is possible, but don't plan on it. You can play Sweet Bonanza free here first to see how it feels.

Rainbet VIP levels
Once the welcome bonus is gone, Rainbet's VIP program is where the ongoing rewards come from: rakeback plus daily, weekly and monthly bonuses, with a VIP host from Platinum IV. There are 25 levels in 7 tiers, and each tier starts at this much total wagering:
- Bronze$0
- Silver$36K
- Gold$95K
- Platinum$500K
- Diamond$7M
- Infernal$250M
- Infernal Diamond$500M
On top of that, Rainbet runs prize races for wagering on any game. When we checked in November 2026 the lobby showed a daily race worth $25,000, a weekly race worth $100,000 and a monthly race worth $1 million, plus a $20,000 weekly raffle.
To see exactly how far you are from the next level, and what the extra wagering is likely to cost, use our Rainbet VIP calculator.

- It was added after sign-upThere's no way to attach a code later, so it has to be in the field before you press Register.
- There's a typo or a spaceType BETARO in capitals with no spaces, or paste it with the copy button on this page.
- The deposit was too smallThe bonus starts at a $30 first deposit. Anything less won't trigger it.

Rainbet.com and Rainbet.us
They're two different sites. Rainbet.com is the crypto casino with the deposit bonus above, and it doesn't accept players from the United States. Open it from the US and you get the message below, pointing you to Rainbet.us instead.
Rainbet.us is a separate sweepstakes social casino. You play with its own coins instead of a crypto balance, it runs its own races, and its sign-up form has an optional referral code field as well.
Is there a no-deposit code?
Not a standing one. Rainbet's welcome offer needs a first deposit, and no-deposit promos only show up now and then in certain regions. Codes promising free money with no deposit are usually out of date.
