Gamdom Promo Code 15BOOST
One code, two places to enter it. Type 15BOOST into the referral field while you register, or add it later through Rewards and Special Rewards. Either route links the account to the 15% rakeback week.
15BOOST
Code copied. Paste it into the referral field when the sign-up form opens.
- ✓ Referral link: gamdom.com/r/15boost
- ✓ Field name on sign-up: Referral Code
What the code provides
Three offers are attached to a new account opened through this referral link. Only the first is exclusive to the code itself.
15% Rakeback for 7 Days
Raises the share of wagering returned to the account for the first week. It applies across the categories you play rather than to a single game.
Enter 15BOOST Welcome100% Deposit Bonus
The standard matched deposit offer for new accounts, claimed from the casino's own rewards area once the account is funded.
Open the cashier Ongoing$1M+ Monthly Leaderboards
A recurring prize pool split across leaderboard places. It is not tied to the referral code and keeps running after the boost week ends.
View standingsActivating during registration
The cleanest route. The sign-up form has a dedicated Referral Code field sitting directly under the password box.
Open the casino through the referral link
Use gamdom.com/r/15boost so the referral is already recognised when the form loads.
Start registration
Select Sign up in the top right corner. The Create Account panel opens over the lobby.
Find the Referral Code field
It is the fourth field on the form, labelled in green underneath Password.
Enter the code
Type 15BOOST exactly. It is not case sensitive on entry, but spaces are worth avoiding.
Complete registration
Confirm the terms and age checkbox, then select Start Playing. The account is created with the referral already attached.
Activating after registration
If the account already exists, the code can be added from the rewards area. Look for Special Rewards underneath the Royalty Up ranks.
Sign in to the account
Open the casino and log in as normal. Signing in happens on the casino itself, never on this site.
Open Rewards
Rewards is in the main navigation bar next to Sports and Affiliates.
Scroll to Special Rewards
The 15% Rakeback for First 7 Days card appears there with a countdown and an Activate button.
Enter 15BOOST in the affiliate field
Selecting Activate opens the Welcome Bonus panel with an Affiliate Code box. Type 15BOOST and confirm with Claim, if the account is still eligible.
Registration field or Special Rewards
Both routes point at the same offer. The difference is timing, and timing is what decides whether the field is still open to you.
| During registration | After registration | |
|---|---|---|
| Where | Referral Code field on the Create Account form | Rewards, then Special Rewards, then the Welcome Bonus panel |
| Field label | Referral Code | Affiliate Code |
| When | Before the account exists | While the Special Rewards offer is still showing on the account |
| Effort | One extra field on a form you are filling in anyway | Three clicks after signing in |
| Risk of missing it | Low, the field is part of sign-up | Higher, because eligibility is checked at that moment |
Eligibility for the Special Rewards route is decided by the casino, not by this site. If the card is no longer displayed on your account, the offer window has closed for that account and no code will reopen it.
Welcome bonus, rakeback and the difference
The welcome bonus
The 100% Deposit Bonus is the classic welcome offer: the casino matches a qualifying first deposit. It is claimed from the casino's rewards area once funds are on the account, and its own terms are shown at the moment you claim it.
It is a one-off event. Once it has been used, it does not repeat, which is why it sits apart from the rakeback track.
The rakeback boost
Rakeback works differently. It returns a share of what you wager over time, so it keeps paying out as long as you are playing. Code 15BOOST lifts that share to 15% for the first seven days after activation.
Because it is tied to activity rather than to a result, it favours steady sessions across Gamdom slots and Originals rather than a single large bet.
Where exactly the code goes
- Sign-up form: the field labelled Referral Code, under Password
- Rewards area: the field labelled Affiliate Code inside the Welcome Bonus panel
- Nowhere else. There is no code box in the cashier or in account settings
The referral link gamdom.com/r/15boost carries the same referral, so opening the casino through it is the safest starting point.
Common activation issues
- The code is rejected. Check for a trailing space or a swapped character. The code is 15BOOST, with the digits first.
- No Referral Code field. The form was opened outside the referral link, or an older cached version of the page is loading. Clear the cache and reopen the link.
- No Special Rewards card. The offer window for that account has passed, or the account is not eligible.
- An account already exists. A second account is not the answer. Use the Special Rewards route on the original account while it is available.
- The page will not load at all. That is a connection problem rather than a code problem. Try another browser or another network before blaming the code.
Promo code questions
Yes. 15BOOST is the referral code used on this site, and gamdom.com/r/15boost is its matching tracking link. The same code appears as a Referral Code at sign-up and as an Affiliate Code in the rewards panel.
No. Entering a referral code does not change prices, odds or which games you can open. It links the new account to the referral and to the rakeback offer attached to it.
Seven days, as stated on the offer itself. The Special Rewards card also shows a countdown timer for the activation window, which is a separate thing from the seven day boost period.
They are listed as separate offers, so they are not alternatives to each other. How they combine on any individual account is set by the casino's promotion terms at the time of claiming, which are shown on the claim screen.
Only if the Special Rewards card is still visible on that account. Referral and welcome offers are normally aimed at new accounts, so an established account may not see the panel at all.
Check that the rakeback shows as active in the rewards area, then decide where the week is best spent. The Gamdom slots guide and the Originals guide both describe how those categories play, and the mobile page covers playing away from a desktop.
