The Rainbet referral code BOOST20, and how to apply it
Enter BOOST20 on Rainbet to attach a 20% Rakeback Boost to a new account. Below you can copy the code in one click, then follow the two ways to activate it — during sign-up or, if you have already registered, through the Deposit section shown in the screenshots.
Copy the code, then open Rainbet
Click the code to copy it to your clipboard and open Rainbet in a new tab. Paste it into the referral, promo or affiliate-code field.
If copying is blocked in your browser, select the code text above and copy it manually. We will not show a success message unless the copy actually works.
♥ The offer
What the 20% Rakeback Boost means
Rakeback is a form of cashback tied to how much you wager. On each bet the house keeps a small margin, and rakeback returns a portion of that margin to your account over time.
Tied to wagering
Rakeback is calculated from your own play, so the amount depends entirely on how much you wager. It is not a fixed lump sum.
Boosted by 20%
The BOOST20 code increases the rakeback share you earn by 20% compared with the standard rate on a new account.
Not guaranteed cash
Because it depends on play, rakeback is never a promised profit. It is a small ongoing rebate, and Rainbet sets the exact rate.
Read before you rely on it. BOOST20 is not advertised as a no-deposit offer, and no code can guarantee winnings or permanent bonus availability. The exact terms, rate and eligibility are decided by Rainbet and can change at any time. Confirm the current details on Rainbet before you play.

♠ Method 1
Activate BOOST20 during registration
The simplest moment to apply the code is while you are creating your account. New sign-ups can enter it directly on the registration form.
- Open the Rainbet sign-up form
Use the referral link or visit Rainbet and start creating an account.
- Find the referral or promo-code field
The sign-up form includes a field for a referral or promo code. If you arrived through the referral link, it may already be filled in.
- Enter BOOST20
Type or paste BOOST20 exactly, with no spaces. Codes are usually not case-sensitive, but copying it avoids typos.
- Finish creating your account
Complete the remaining sign-up details. The 20% Rakeback Boost should then be linked to your new account.

Activate BOOST20 after registration, in the Deposit section
Already made an account without a code? You may still be able to add it. Rainbet places an affiliate-code option inside the Deposit area, labelled for new users and claimed before depositing. The screenshots below show exactly where to look.
- Sign in to your Rainbet account
Log in with the account you want the boost applied to.
- Open the Deposit section
Go to the Deposit area. Along the top you will see tabs including Deposit, Withdraw, Buy Crypto, Tip and Redeem.
- Choose “Redeem Affiliate”
On the right of the Deposit panel, select the Redeem Affiliate card. Rainbet notes it is to be claimed before depositing and is intended for new users, so apply it early.
- Enter BOOST20 in the Affiliate Code field
The panel reads “Redeem an affiliate code here to claim possible rewards.” Type or paste BOOST20 into that field.
- Select “Redeem Affiliate Code”
Confirm with the Redeem Affiliate Code button to apply it before you complete any deposit.
Interface labels and layout can change. Follow the on-screen wording you actually see — the labels above match the current Deposit and Affiliate Code screens.
Add BOOST20 from the Deposit section
Sign in, open the Deposit area, choose Redeem Affiliate, and enter the code before your first deposit.

Common activation issues and how to check them
The code is rejected
Re-enter BOOST20 using copy-and-paste to rule out a typo or a stray space. Confirm you are on the affiliate or referral field rather than a different box.
The option is greyed out
Rainbet marks the affiliate-code option for new users, claimed before depositing. If you have already deposited, the window to add it may have closed on your account.
Nothing happens after redeeming
Refresh the page or sign out and back in. If the boost still does not appear, contact Rainbet support directly, since only they can view your account status.
You used a different code
Only one referral or affiliate code usually applies per account. If another code is already attached, BOOST20 may not stack on top of it.
We cannot see or change your Rainbet account. For anything tied to your specific account — eligibility, timing or a missing boost — Rainbet support is the right place to ask.
♠ Same code, different names
Referral code, promo code or affiliate code?
You will see all three terms used for BOOST20. In this specific context they point to the same thing, but the wording differs depending on where you are.
♠ Referral code
The everyday name for a code shared by an existing player or partner. Entering it links your new account to the person or site that referred you and unlocks the 20% Rakeback Boost.
♥ Promo code
A general term people use for any code that carries an offer. BOOST20 is often called a promo code, even though on Rainbet the on-screen field is not always labelled “promo”.
♣ Affiliate code
The exact label Rainbet uses in the Deposit section: “Affiliate Code” with a “Redeem Affiliate Code” button. It is the same BOOST20 code, entered after registration.
Use Rainbet Referral Code BOOST20
Enter BOOST20 during registration, or add it through the Deposit section after creating an account.
Using the boost sensibly
A rakeback boost is a small rebate on wagering, not a reason to bet more than you planned. Decide your budget first, then treat any rakeback as a minor extra on top — never as expected income or a way to chase losses. The offer does not lower blackjack’s built-in house edge, and it cannot make play risk-free.
Gambling is for adults of legal age in your province or territory (18 or 19+) and involves real financial risk. If it stops being fun, free and confidential help is available through provincial services. Nothing here is legal or financial advice.
