Pasting a trailing space
Copying the code from a forum post often drags a space along with it. The field reads that as a different code. Use the copy button on this page instead.

Rainbet promo code BOOST20 and the 20% Rakeback Boost
One code, one benefit, two places to enter it. This page shows exactly where BOOST20 goes during registration and how to redeem it afterwards from the Deposit panel — using the real Rainbet screens rather than a description of them.

The offer
What the Rainbet bonus code actually does
BOOST20 is a referral code. When it is attached to an account, that account receives a 20% Rakeback Boost — the rakeback rate on your play is lifted by twenty percent. There is nothing else bundled with it, and we are not going to pad this page with invented deposit minimums, spin counts or expiry dates.
Two things follow from that. First, the value is proportional: a player who wagers a little gets a little back, and a player who wagers a lot gets more back. Second, it is not a prize. Nobody is handing you a set amount of NZ$ for typing in a code.
The remaining terms — how rakeback accrues, when it becomes claimable, which games contribute — are set by the operator and shown on the platform itself. Read them there before you deposit.
What is confirmed Verified ✅
Code BOOST20 · benefit: a 20% Rakeback Boost · entry points: registration form or the Redeem Affiliate option in the Deposit panel.
What we will not claim
No free spins figure, no minimum deposit, no wagering multiplier, no expiry window and no guaranteed cash amount. If you see those attached to this code elsewhere, treat them with suspicion until the platform states them.
Method one
Activating BOOST20 during registration
The simplest route. Opening Rainbet through the link below carries the referral with you, so the code arrives pre-filled or ready to confirm.
-
Open Rainbet through the referral link
Use the button below. The
?r=boost20parameter on the URL is what associates your new account with the code. -
Start the sign-up form
Select Register in the top-right of the site header and enter your email address, a password and your date of birth. You must be 18 or over.
-
Find the referral or promo code field
The registration form includes an optional field for a referral, affiliate or promo code. If it is collapsed behind a small link, expand it before you submit.
-
Enter BOOST20 and complete registration
Type or paste
BOOST20exactly, then finish the form. If the field was already filled in by the link, just confirm it reads BOOST20 before submitting.
If you cannot see a code field
Some registration flows hide the referral field entirely when the code is already carried by the link — that is normal and it does not mean the code was lost. It also is not a dead end: you can still add the code afterwards from the Deposit panel, which is covered directly below.
Method two
Activating BOOST20 after registration from Deposit Verified ✅
Already signed up without the code? The affiliate code can be redeemed from inside the wallet. The two screenshots below are the actual screens you will be looking at.
-
Sign in to your account
Log in on the official domain. If you are having trouble getting in, the Rainbet login guide covers recovery and common errors.
-
Open the Deposit area
Open your wallet and select the Deposit tab. It sits first in a row alongside Withdraw, Buy Crypto, Tip and Redeem.
-
Select Redeem Affiliate
In the right-hand column of the Deposit panel, above Rainbet Gift Cards and Buy Cryptocurrencies, there is a Redeem Affiliate card. Its own subtitle reads "Claim before depositing, new users only" — so do this step before you fund the account.
-
Enter BOOST20 in the Affiliate Code field
The redeem screen is headed Affiliate Code and explains that redeeming a code here claims possible rewards and credits the player who referred you. Type
BOOST20into the input box. -
Confirm with Redeem Affiliate Code
Select the green Redeem Affiliate Code button underneath the field. A "Go Back" control sits at the top of the screen if you need to return to the Deposit panel.
Only the steps shown
Everything above is taken from the two screenshots on this page. If your version of the interface looks different, follow what is on your screen rather than this guide — the platform updates its layout from time to time.
Plain English
What rakeback actually means
Every bet you place carries a built-in margin for the house. Rakeback gives a percentage of that margin back to you, regardless of whether the individual bet won or lost. It is a rebate on the cost of playing, not a reward for winning.
A 20% Rakeback Boost raises the rate at which that rebate accrues by a fifth. If your baseline rakeback would have been the equivalent of NZ$10 over a session, a 20% boost makes it NZ$12. Modest, ongoing, and directly tied to volume.
Because it scales with how much you wager, rakeback should never be a reason to bet more than you planned. The rebate is always smaller than the margin it comes from — that is the whole point of it from the operator's side.

| Baseline rakeback earned | With a 20% Rakeback Boost |
|---|---|
| NZ$5.00 equivalent | NZ$6.00 equivalent |
| NZ$25.00 equivalent | NZ$30.00 equivalent |
| NZ$100.00 equivalent | NZ$120.00 equivalent |
Illustrative arithmetic only, shown in NZD equivalents for readability. Actual rakeback rates, accrual rules and balances are set by the platform and held in cryptocurrency.
Troubleshooting
Common promo code mistakes
Depositing first
The Redeem Affiliate card says to claim before depositing. Funding the account first can put the code out of reach.
Registering on a lookalike domain
A code entered on a copycat site does nothing except hand your details to whoever built it. Check the address bar before you type anything.
Already using another referral
Accounts are normally linked to a single referral. If one has already been applied, BOOST20 will be rejected — that is expected behaviour, not a fault.
Typing a lower-case variation
Enter it as BOOST20. Do not substitute the digits, add hyphens or split it across the field.
Assuming it is a cash bonus
Waiting for a balance to appear after redeeming leads to confusion. Rakeback builds as you play; nothing lands the moment you confirm the code.
Before you claim
Terms worth reading on the platform itself
We deliberately do not restate promotional terms we cannot verify. These are the specific things to look up in Rainbet's own terms and promotions pages.
- The current rakeback rate and how the 20% boost is applied to it.
- Which game categories contribute to rakeback and at what weighting.
- When accrued rakeback becomes claimable and how it is credited.
- Whether any minimum activity is required before a claim is possible.
- Country and territory restrictions that apply to New Zealand accounts.
- Identity verification requirements before a withdrawal is processed.
- Whether more than one promotion can run on an account at once.
- Any changes the operator has made since this page was written.

FAQ
Rainbet promo questions
No. BOOST20 is a referral code that applies a 20% Rakeback Boost. Rakeback is generated by your own wagering, so the value depends entirely on how much you play rather than a fixed payout.
The Redeem Affiliate card in the Deposit panel states that the code should be claimed before depositing and is for new users only, so enter BOOST20 before you fund the account.
Enter it exactly as BOOST20, in capitals and with no spaces. Copy-paste from this page is the safest way to avoid a typo.
Check for a trailing space from a paste, confirm you are on the official domain, and confirm the account has not already had another referral code applied. An account can normally only be linked to one referral.
No. Applying a referral code does not add a fee to your deposit. This site earns a commission if you register through our link, which is why the code and link are shown together.
On rainbet.com itself. Promotional mechanics and rakeback rates are set by the operator and can change without notice, so the live terms always take priority over any guide, including this one.
Apply BOOST20 to a new account
Open the platform with the referral attached, then confirm the code either on the registration form or from Redeem Affiliate in the Deposit panel.
