Gamdom Promo Code 15BOOST - Welcome bonus & boosted rakeback for new accounts
Add 15BOOST when you sign up, or within 6 hours after, and Gamdom boosts your Instant Rakeback to 15% for the first 7 days. Copy the code, open Gamdom and follow the steps below.
Real Gamdom sign-up form: the Referral Code field accepts 15BOOST directly.
01 The code
Gamdom referral code 15BOOST
15BOOST is the affiliate code attached to this campaign. It connects your new Gamdom account to a referrer, and that link is what unlocks the boosted rakeback. It is worth knowing how that differs from a normal promo code.

04 Deposit bonus
The 100% welcome deposit bonus
A 100% deposit bonus means Gamdom matches a qualifying deposit with the same amount again in bonus funds. It is listed as one of the headline benefits of this campaign, alongside the rakeback boost.
What we do not publish here are fixed caps, wagering figures or expiry dates, because those details are set by Gamdom and can change at any time. Open the bonus details in your account before you deposit and make sure you are happy with the conditions.
Gamdom's Instant Rakeback (also shown as Instant Rewards) is a small reward generated from every bet. The amount depends on things like your stake, the game's RTP and your overall activity, and Gamdom does not publish the exact formula.
Your betsGameplay factors15% boosted rewardClaim in Rewards
With 15BOOST active, that reward rate is boosted to 15% for your first 7 days. It is not 15% of every wager handed back as cash, and it does not change the odds of any game. Think of it as a bigger share of the platform's reward pool while the boost lasts.
06 FAQ
Gamdom promo code questions
The code we use is 15BOOST. Strictly speaking it is a Gamdom affiliate (referral) code rather than a one-off voucher, but it is what most people mean when they search for a Gamdom promo code: a code you add to a new account to unlock a welcome benefit.
Either type it into the Referral Code field while creating your account, or, after registering, open Rewards, find the Special Rewards card, press Activate, enter 15BOOST in the Affiliate Code field and press Claim.
There are two places. On the sign-up form, the Referral Code field sits under the password field. After registration, the code goes into the Affiliate Code field that appears when you activate the Special Rewards card on the Rewards page.
Gamdom currently allows affiliate codes to be added within 6 hours of registration. The Special Rewards card shows a countdown, so you can see how much of that window is left.
For the first 7 days after activation, eligible new users get their Instant Rakeback boosted to 15%. Instant Rakeback is calculated from your bets using factors such as stake size and the game's RTP, so it is not 15% of your wagers paid back as cash. It builds up as you play and is claimed from the Rewards page.
It is an affiliate code. It links your new account to a referrer and triggers the boosted rakeback. Redeemable promo codes are a separate thing that Gamdom may issue for individual promotions.
No. According to Gamdom's help centre, once an affiliate code has been added to an account it cannot be changed, so check the spelling before you press Claim.
Open Rewards from the top navigation on Gamdom. Below your progress bar and the rank-up tiers there is a section called Special Rewards, where the 15% Rakeback card for new accounts appears.
The 15BOOST campaign lists a 100% deposit bonus among its highlights. The exact eligibility, amounts and conditions are set by Gamdom and can change, so read the offer details in your account before you deposit.
