Rainbet Promo Code and Referral Code: BOOST20
BOOST20 is the code Canadian players can attach to a new Rainbet account for a 20% rakeback boost. It can be entered while registering — or redeemed afterwards through the Deposit section, which is the part most guides skip. Both routes are documented below with screenshots.
Terms and availability are set by Rainbet and can change. 18+/19+ depending on your province.

Because rakeback scales with wagering rather than paying a fixed amount, its value differs from player to player. Someone wagering CA$100 a week will see far less returned than a high-volume player — and either way, rakeback softens the house edge rather than eliminating it. If you're new to how the games themselves pay, our guide to Rainbet slots and games explains RTP and volatility.
One thing BOOST20 is not: the welcome bonus. Rainbet's first-deposit welcome promotion — including any free spins and welcome bonus options — is chosen separately through the Promotions section before you deposit, and it carries its own terms.
Mechanically, the code works through Rainbet's RakeBoost system: affiliate code redemption is currently listed as a +20% boost for 72 hours, applied to the reward rate rather than to your wagers themselves. How rakeback accrues, when it can be claimed and how the Daily, Weekly and Monthly Bonuses work is covered in our rakeback and recurring bonuses guide.
Applying the Code During Registration
The simplest route: attach BOOST20 at the moment you create the account.
- Open Rainbet. Use a link with the code attached — the button below already includes it — or go to the site directly.
- Choose Register. Fill in your email address, a username and a strong password.
- Find the referral code field. Look for the promo, referral or affiliate code input on the registration form. It may sit behind a small expandable link.
- Enter BOOST20. Type it exactly, with no spaces before or after.
- Complete sign-up. Confirm your email if asked, then check your account or rewards area to see that the code is attached.
Forgot the field during sign-up? Don't create a second account — duplicate accounts usually breach casino terms. Use the post-registration method below instead.
How to Add BOOST20 After Registration
Already have an account with no code attached? Rainbet's cashier includes an affiliate redemption option — its interface has marked it as being for new users, claimed before your first deposit. Here is the process, step by step.
- Sign in to your Rainbet account. New here? See our Rainbet login instructions first.
- Open the Deposit section. The wallet or deposit button in the header opens the cashier with tabs for Deposit, Withdraw, Buy Crypto, Tip and Redeem.
- Find the promo or referral code option. On the Deposit tab, look for the Redeem Affiliate panel — in Rainbet's cashier it appears beside the currency steps, noting it should be claimed before depositing.
- Enter BOOST20. The Affiliate Code screen has a single input field — type the code and press Redeem Affiliate Code.
- Confirm your deposit and check the boost. Once the code is accepted, make your deposit as normal, then check your rewards or VIP area to see whether the rakeback boost shows as active.
No guarantees: whether the code is accepted depends on your account status, region and Rainbet's current promotional conditions, all of which can change. If redemption fails, the troubleshooting list further down covers the usual causes.
Referral Code, Promo Code or Affiliate Code?
Referral code
The general term for a code that links your new account to whoever referred you. Rainbet's registration form treats BOOST20 this way — the code credits the referrer and unlocks the associated rewards for you.
Promo code
How most players search for it. In practice "Rainbet promo code" and "referral code" point to the same input fields. There is no separate coupon system that takes a different BOOST20.
Affiliate code
Rainbet's own label inside the cashier, where the redemption screen is titled "Affiliate Code." Same code, same effect: it ties your account to the 20% rakeback boost.
Whichever name you use, one rule holds: an account generally carries one code, attached once. Choose before you deposit, because the cashier route is described as pre-deposit only.
Eligibility and Possible Restrictions
- You must meet the legal gambling age for your province or territory — 18+ in some, 19+ in most.
- The cashier redemption route is labelled for new users, before a first deposit.
- One account per person; codes can't be stacked or swapped after attachment.
- Regional restrictions can apply, and some games or promotions may be unavailable in parts of Canada.
- Rainbet can amend or withdraw promotions at any time — the platform's current terms always take precedence over any guide, including this one.
Common Code-Entry Problems
- Typos and stray spaces — the code is one word: BOOST20, with a zero, not the letter O at the end.
- A code is already attached — accounts that registered with another referral usually can't add a second one.
- Deposit already made — pre-deposit redemption may no longer be offered once you've funded the account.
- Region blocks — if the cashier or promotion isn't shown in your province, the option may simply not be available to you.
- Still stuck? Rainbet's support chat is the definitive source for what your specific account is eligible for.
BOOST20 FAQ
Where do I enter the Rainbet promo code BOOST20?
There are two places: the referral code field shown during registration, and the Redeem Affiliate option inside the Deposit section of the cashier after your account is created. The cashier route has been marked as available to new users before their first deposit.
Is BOOST20 a promo code, a referral code or an affiliate code?
All three labels get used for the same thing. Rainbet's own interface calls it an affiliate code, and it works like a referral: entering it links your account to the code's rewards, in this case a 20% rakeback boost, subject to Rainbet's current terms.
What is the 20% rakeback boost worth?
Rakeback returns a percentage tied to the house edge of your wagers. The boost raises that rate by 20% relative to the standard rate. The real value depends on how much you wager, the games you play and Rainbet's current rakeback rules, so there is no fixed dollar figure.
I already deposited — can I still redeem the code?
Rainbet's cashier has described affiliate redemption as being for new users, to be claimed before depositing. If you have already made a deposit, the option may no longer apply to your account. Rainbet support can confirm what is possible in your specific case.
Does the code guarantee the bonus for every Canadian player?
No. Eligibility, availability and terms are decided by Rainbet and can change at any time. Regional restrictions may also apply depending on your province or territory. Always check the current terms on the platform before relying on any promotion.
The code field will not accept BOOST20 — what should I check?
Check for typos and extra spaces, make sure your account has no other code already attached, and confirm you have not already deposited if the option is limited to pre-deposit accounts. If it still fails, contact Rainbet support through the site.
Attach BOOST20 to Your Account
Enter the code during sign-up, or redeem it in the Deposit section before your first deposit. Play within a budget you set in advance — rakeback reduces the house edge, it never removes it.
