Gamdom promo code 15BOOST
One code, entered once, in one of two places. It attaches your account to this referral and releases the exclusive 15% rakeback that runs for seven days, on top of the standard Gamdom welcome bonus.
What the 15BOOST code unlocks
15% rakeback
For your first 7 days. A share of the house edge on every wager comes back to your balance whether the bet won or lost.
100% deposit bonus
Gamdom's welcome match on your first deposit. Cap and wagering shown in the cashier.
$1M+ leaderboards
Monthly wagering races across casino and sportsbook, refreshed every month.
The three rewards at a glance
Rakeback
15% of the house edge returned for 7 days, credited to your normal balance.
Deposit match
The standard 100% Gamdom welcome bonus applies alongside the referral.
Leaderboards
Wagering races with a combined pool above CA$1M every month.
No waiting
The code applies the moment it is accepted. There is no approval queue.
Enter the code while you create the account
This is the cleanest route because the referral is attached before the account exists. The field is labelled Referral Code and sits under the password box.
Open Gamdom through the referral link
Use the button on this page. The referral travels with the link, so the field is often filled in for you already.
Select Sign up
The Create Account panel opens with username, email and password fields. Google, Telegram and Steam sign-in are also offered.
Type 15BOOST into Referral Code
Exactly as written, no spaces. The field border turns green when the code is recognised.
Tick the terms box and select Start Playing
You confirm you accept the terms and meet the legal minimum age for your province before the account is created.
Add the code afterwards through Rewards
Already registered without a code? Open Rewards, scroll past the Royalty Up tiers to Special Rewards, and the Welcome Bonus panel takes the same code.
What you should see afterwards
- The Special Rewards card reads 15% Rakeback · For First 7 days
- A countdown replaces the Activate button once it is running
- Rakeback lands in your main balance, not a locked bonus wallet
- If nothing appears, refresh the page before contacting support
The whole process in seven steps
Open Gamdom using the referral link
Everything on this page points at the same destination.
Start registration
Select Sign up in the top right corner of the Gamdom header.
Enter 15BOOST in the referral or promo code field
Under the password box on the Create Account panel.
Complete account creation
Accept the terms, confirm your age and select Start Playing.
Or, if the account already exists, open Rewards then Special Rewards
Scroll past the Royalty Up tier row.
Enter 15BOOST in the Affiliate Code field and select Claim
This is the Welcome Bonus dialog.
Check that the reward is active
The rakeback card should show a running countdown rather than an Activate button.
What 15% rakeback actually returns
Rakeback is a share of the house edge, not a share of your losses and not a share of your turnover. The edge is the small built-in margin on each game, so the return scales with how much you wager rather than how the individual rounds land.
That makes it most useful on high-frequency Originals. A thousand small Dice rolls generate far more rake than one large slot spin of the same total value, because the wager count is what drives the accrual.
The table below is an illustration of the mechanic using round numbers. It is not a payout promise and the real figures depend on the games you play and Gamdom's own terms.
| Total wagered in 7 days | Assumed house edge | Rake generated | 15% returned |
|---|---|---|---|
| CA$500 | 2% | CA$10.00 | CA$1.50 |
| CA$2,000 | 2% | CA$40.00 | CA$6.00 |
| CA$5,000 | 2% | CA$100.00 | CA$15.00 |
| CA$20,000 | 2% | CA$400.00 | CA$60.00 |
How the rewards differ
They stack, but they behave nothing alike. Knowing which is which stops you from planning around the wrong one.
| Reward | Trigger | Runs for | Best for |
|---|---|---|---|
| 15% rakeback | Code 15BOOST on the account | 7 days from activation | High round counts on Originals |
| 100% deposit bonus | First qualifying deposit | Until the wagering condition is met | Extending a single larger bankroll |
| Monthly leaderboards | Automatic once you wager | Calendar month | Sustained volume across the month |
Four things to check before you contact support
01 Exact spelling
15BOOST is one word, no hyphen, no space. Autocorrect on a phone keyboard is the usual culprit.
02 Right field
At sign-up the label reads Referral Code. In Rewards it reads Affiliate Code. They accept the same value.
03 Already attributed
An account linked to a different referral cannot be reassigned. Only an account with no referral attached can take the code.
04 Stale page
Reload the Rewards page after claiming. The card state is cached and does not always repaint on its own.
Gamdom promo code questions
What is the current Gamdom promo code?
15BOOST. It is the affiliate code used across this site and it links a new account to this referral, which is what releases the 15% rakeback for the first 7 days.
Where do I enter the Gamdom affiliate code?
Two places. During registration there is a Referral Code field directly beneath the password box on the Create Account panel. After registration, open Rewards and scroll to Special Rewards, where a Welcome Bonus panel asks for the Affiliate Code.
Does the promo code cost anything or change my terms?
No. The code only attributes the account to a referral. It does not change deposit limits, withdrawal rules or the games you can open, and there is no charge for using it.
How long does the Gamdom welcome bonus rakeback last?
The rakeback element runs for 7 days from activation. After that your account returns to the standard rakeback tier tied to your VIP level.
Can I use 15BOOST on an account I made months ago?
The Rewards route is designed for accounts that have not yet been attributed to a referral. If the Special Rewards panel no longer shows a Welcome Bonus card, the window for that account has passed and Gamdom support can confirm what is still available.
What happens if I skip the code field during sign-up?
Nothing breaks, but the rakeback does not start. Go to Rewards, then Special Rewards, and enter 15BOOST there before you start wagering so the full seven days count.
Is rakeback the same thing as cashback?
They are close but not identical. Cashback usually returns a percentage of net losses. Rakeback returns a share of the house edge on every wager, so it accrues whether the individual bet won or lost.
One note on bonus terms
Bonus mechanics on any casino change without notice, and Gamdom is no exception. The figures on this page reflect what the 15BOOST referral releases at the time of writing: 15% rakeback for seven days, alongside Gamdom's own 100% deposit bonus and the monthly leaderboards.
What this page deliberately does not do is invent wagering multipliers, maximum bonus caps or expiry windows that were not published. Those numbers live in the cashier and the promotions panel inside your account, and that is the version that counts. Read them there before you deposit.
Put 15BOOST on your account
Open Gamdom through the referral link, enter the code at sign-up or in Rewards, and the 15% rakeback starts running immediately.
