What the code unlocks

Three separate rewards. The rakeback is the one you only get through 15BOOST — the other two are Gamdom's standard welcome offers, attached automatically.

Activation guide

Two ways to apply the Gamdom affiliate code

Use whichever fits. New players add the code in the sign-up form; existing accounts can add it from the Rewards page.

Method 1

During registration

The quickest route. The referral field is part of the sign-up form, so the reward is linked before you make a deposit.

  1. Open the registration page — use the button below to land on Gamdom's sign-up form.
  2. Find the referral / affiliate code field in the form (it may sit behind a "have a code?" toggle).
  3. Enter 15BOOST exactly as shown.
  4. Complete registration and verify your email. The 15% rakeback reward appears under Rewards.

Method 2

After registration

Already have an account without a code? You can still activate the welcome reward from your Rewards page — as long as the timer on the reward card has not run out.

  1. Sign in to your Gamdom account.
  2. Open Rewards from the top navigation.
  3. Scroll to Special Rewards and press Activate on the "15% Rakeback for First 7 days" card.
  4. In the Welcome Bonus window, type 15BOOST into the Affiliate Code field and press Claim.

The Special Rewards card carries a countdown. If you registered without a code, activate the reward before the timer ends — otherwise the 7-day rakeback window cannot be added later.

Good to know

How rakeback and the deposit bonus fit together

Rakeback is the simplest reward on the site: a fixed percentage of the house edge on each bet is returned to a claimable balance, regardless of whether the bet won. With 15BOOST that rate is 15% for the first seven days, which is higher than the entry ranks of Gamdom's standard loyalty ladder.

The 100% deposit bonus works separately. It matches a qualifying first deposit and unlocks according to wagering requirements shown in the Rewards area. Because the two rewards are independent, you can play on rakeback alone if you prefer not to take a wagering-bound bonus.

Leaderboards

Monthly leaderboards rank players by wagering across selected slots and Originals, with prize pools that regularly exceed $1M combined. Entry is automatic once your account is active; positions and prize tiers are displayed inside the site.

Code checklist

Type 15BOOST in capital letters with no spaces. The site accepts it in the sign-up form and in Rewards → Special Rewards.

Crypto deposits

The deposit bonus applies to crypto deposits made through the cashier. Minimums and conversion rates are displayed at deposit time.

One per player

Welcome rewards are limited to one account per person. Duplicate accounts are not eligible and can lead to forfeited bonuses.
