Two ways to apply your Rainbet promo code

Rainbet treats the referral code, promo code and affiliate code as the same thing — one field that links your account to a partner and, in this case, unlocks a rakeback boost. There are two moments you can enter BOOST20: during registration, or afterwards from inside your account. Pick whichever suits where you are right now.

Method 1

During registration

The quickest path is to add the code as you create the account, so the boost is attached from your very first deposit.

  1. Open the Rainbet sign-up form using code BOOST20 — the button below takes you there directly.
  2. Fill in your account details as normal (email, username and password).
  3. Find the referral / promo code field. If it is collapsed, expand the “Referral code” or “Promo code” option.
  4. Enter BOOST20 exactly as shown.
  5. Complete registration. The 20% rakeback boost is now linked to your new account.

Method 2

After registration

Already signed up without a code? You can still redeem BOOST20 through the Deposit section. New users are usually eligible to claim it before their first deposit.

How to enter the Rainbet referral code after registration

Follow these five steps inside your account. The screenshots show exactly where the affiliate code field lives so you don't have to hunt for it.

  1. Sign in to your Rainbet account.
  2. Open the Deposit section from the top of the interface.
  3. Locate the “Redeem Affiliate” card — it sits to the right of the deposit panel and is meant for new users claiming before depositing.
  4. Enter BOOST20 in the affiliate code field.
  5. Confirm the code with “Redeem Affiliate Code,” then continue with your deposit.

BOOST20 provides a rakeback boost — a portion of house margin returned based on your activity — rather than a guaranteed cash amount. Its value depends entirely on how you play, so we don't promise a fixed figure.
