- Games: crash, roulette, originals, slots; skin deposits accepted.
Where some codes hand you a case, 15BOOST at Gamdom hands you a match and a clock. A 100% deposit bonus doubles what you put in (subject to terms), and a 15% rakeback boost runs for seven days. The combination rewards players who intend to be active that week rather than casual visitors.
How the two halves work
The 100% deposit bonus
A 100% match means a CA$100 deposit could be matched with up to a further CA$100 in bonus value, usually capped. The cap, the eligible deposit range and the play-through are the site's to define. The headline is attractive, but the play-through is what decides its real value. Use the wagering calculator before you commit.
The 15% rakeback for 7 days
Rakeback returns part of the house edge on your bets, so a 15% boost applies to that share, not to your stakes. Over seven days, the dollar value depends entirely on how much you wager. Model it in the rakeback calculator, and read what is rakeback if the idea is new.
Claim path
- Confirm you meet your province's age rule and are happy playing offshore.
- Register via our link.
- Enter 15BOOST in the code field at sign-up or in your promo settings.
- Make your first deposit by skins or crypto; the match applies to that deposit as set out in the terms.
- Note the date and time the 7-day rakeback starts, and plan to play within it.
Terms in general terms
- Match bonuses commonly need to be wagered a set number of times before withdrawal.
- Some games count less, or not at all, toward the requirement.
- Maximum bet limits often apply while a bonus is active.
- Bonus offers can have an expiry.
We do not quote numbers because they change; the live terms in your account rule.
What it looks like in practice
| Deposit | Match at 100% (illustrative) | Total starting balance |
|---|---|---|
| CA$50 | CA$50 | CA$100 |
| CA$150 | CA$150 | CA$300 |
| CA$500 | Likely capped; check limit | Depends on cap |
The bigger starting balance does not change the odds. It only means you can wager more before it runs down, which is how the play-through gets cleared.
Suits and doesn't suit
- Suits: players who want to deposit anyway, enjoy crash or roulette, and will be active for a week.
- Doesn't suit: anyone who wants to try the site without depositing, or who hates play-through conditions. A free-case code like CSGOEmpire's case2go is gentler.
Tips for the week
- Deposit what you would spend anyway. Never deposit to chase a bonus.
- Pick lower-variance play to clear requirements. Try the crash simulator and mines simulator to feel the swings.
- Respect the clock, not the pressure. A 7-day window is not a reason to bet more.
- Write down your stop-loss using the bankroll calculator.
Paying from Canada
Gamdom accepts skins and crypto. Canadians usually purchase crypto at a FINTRAC-registered exchange funded by Interac e-Transfer or a transfer from RBC, TD, Scotiabank, BMO or CIBC. For skins, see how to deposit skins. Winnings and crypto disposals may have tax consequences; see our tax guide.
Against the competition
Roobet offers a 100% bonus up to $1,000 with no code, and Shuffle pushes to 200%. Gamdom's differentiator is the rakeback layer and skin deposits. Our Gamdom vs Roobet article lines the two up directly.
Skins on Gamdom: a practical angle
Unlike purely crypto-based casinos, Gamdom accepts CS2 skins as deposits, so a player with a spare inventory can use it rather than buying crypto. Your skins are credited at the site's valuation, which can differ from market prices, so compare before you send anything. Our skin deposit guide and trade URL guide walk through the setup, and Steam Trade Protection explained covers holds that can delay trades.
| Check | Why it matters |
|---|---|
| Site valuation vs market price | A low valuation quietly costs you value |
| Trade hold status | Can delay the deposit and the rakeback window |
| Minimum deposit | May affect bonus eligibility |
Timing the seven days
Since the rakeback boost lasts a week, avoid claiming when you will not have time to play. If you only have two free evenings, you may use only a fraction of the window. Equally, do not stretch your play to fill it. A quiet week with no play simply earns no rakeback, and that is fine.
Step-by-step review before and after the week
| When | Do this |
|---|---|
| Before depositing | Read bonus terms, screenshot them, set a budget |
| On deposit | Confirm the match is credited and note the wagering counter |
| During the week | Check rakeback is accruing; stick to your limit |
| After day seven | Review outcomes and decide whether to continue |
Games to know
Gamdom covers crash, roulette, in-house originals and slots. Crash and roulette are fast, which suits clearing requirements but also accelerates losses. Our crash strategy and roulette strategy guides explain the maths, and the shared rule applies: no pattern overcomes the edge.
Who should say no
Skip the match if you expect to play only once or twice, if you dislike conditions on withdrawals, or if you are already overspending on gambling. In those cases, a simpler offer or no deposit at all is the better call.
Our verdict on 15BOOST
15BOOST is a two-part offer for committed week-long play. The 100% match is attractive only if you can handle its conditions, and the 15% rakeback is a short-term bonus on top. Gamdom's acceptance of skins gives it a practical advantage for players with inventory. If you would rather not deal with play-through, a free-case code is the lighter route. If you like the idea of a match plus rakeback, 15BOOST is among the more balanced packages we track.
Whatever you choose, do not let a seven-day window dictate your behaviour. A deadline is marketing. Your limits are what matter.
FAQ extras
Can I claim the match without the code?
Possibly, but the rakeback boost is tied to the code, so enter it.
Does the 7 days restart if I deposit again?
Assume not unless the site's terms say so.

Frequently asked questions
What does 15BOOST give?
As advertised, 15% Rakeback for 7 days plus a 100% deposit bonus. Exact rules are set by the site.
Is a 100% deposit bonus free money?
No. Matches almost always come with a play-through before the bonus balance can be withdrawn, so read the terms first.
How long does the rakeback last?
The offer describes a 7-day window. Confirm when the clock starts in your account.
Can I deposit skins at Gamdom?
Yes, skin deposits are supported, alongside crypto. Interac is not a direct option.
Is Gamdom available in Ontario?
It is not licensed by iGaming Ontario or the AGCO. Check your provincial rules.
