How the package is built
Monster Win advertises the welcome offer as "300% up to C$4,500 + 300 FS". That figure is the sum of three identical bonuses, one per deposit:
| Deposit | Match | Max bonus | Free spins | Min deposit |
|---|---|---|---|---|
| 1st | 100% | C$1,500 | 100 on Gates of Olympus | C$30 |
| 2nd | 100% | C$1,500 | 100 on Gates of Olympus | C$30 |
| 3rd | 100% | C$1,500 | 100 on Gates of Olympus | C$30 |
| Total | — | C$4,500 | 300 |
To get the full C$4,500 you'd need to deposit C$1,500 three times. Most players won't, and that's fine: a C$50 deposit gets a C$50 match and the same 100 spins as a C$1,500 one. The spins are the part of the offer that doesn't scale with your deposit.
Claiming it step by step
- Register on the Canadian site and choose CAD as your currency.
- Deposit at least C$30 with a qualifying method. Interac and cards qualify; Skrill and Neteller deposits don't.
- Open My Bonus in your profile and activate the welcome promotion — before you place a single bet with that deposit. Once you've played with the money, it's too late for that deposit.
- Check your balance. The bonus should appear immediately. If it doesn't, contact live chat or email support@monsterwin.com rather than starting to play.
- Repeat for the second and third deposits once the previous bonus is finished.
There's no promo code to type in. Codes you see on third-party sites for the welcome package are either for other offers or out of date.
What x35 on deposit + bonus really means
This is where the offer gets expensive. Many casinos apply wagering to the bonus only; Monster Win applies it to the deposit and the bonus together. So the requirement is effectively x70 on the bonus amount.
| You deposit | Bonus | Wagering base | Bets required (x35) | Per day over 10 days |
|---|---|---|---|---|
| C$30 | C$30 | C$60 | C$2,100 | C$210 |
| C$100 | C$100 | C$200 | C$7,000 | C$700 |
| C$500 | C$500 | C$1,000 | C$35,000 | C$3,500 |
| C$1,500 | C$1,500 | C$3,000 | C$105,000 | C$10,500 |
Ten days is the hard limit for each bonus. If you don't finish, the bonus and anything won with it are removed. Before you activate, ask yourself honestly whether you'll place that volume of bets in that window. If not, playing without the bonus is often the better deal — your deposit stays withdrawable at any time.
The caps that limit what you can win
10× the bonus
The most a bonus can release to your real balance is 10 times the bonus amount. Monster Win's own example: a C$15 bonus can turn into at most C$150 of withdrawable money. On a C$100 match, the ceiling is C$1,000 — anything above that is cancelled when the bonus converts.
Free-spin winnings
Spin winnings carry their own x40 wagering and their own cap: up to C$75 can be released from 50 free spins or fewer, and up to C$150 from more than 50. Since each welcome deposit gives 100 spins, the realistic ceiling is C$150 per batch. You also have to finish any active casino bonus before the spins can be used.
Maximum bet
While a casino bonus is active, the biggest bet allowed is C$150. Breaking this — even on one spin — is a classic reason casinos void winnings, so set your stake before you start and leave it.
Things that cancel the bonus
- Requesting a withdrawal before the bonus is claimed or while it's active.
- Activating another bonus or claiming bonus spins while one is running — the current bonus and its winnings are removed.
- Missing the 10-day wagering deadline.
- Cancelling the bonus yourself from your profile (allowed at any time, but the whole bonus balance goes with it).
Cancelling isn't always bad. If you've hit a nice win early with your own deposit and don't fancy the wagering, ending the bonus can be the cleanest way out — just know the bonus money disappears.
Other Monster Win promotions

Cashback offers are usually the better value for regular players, since there's no up-front wagering race. Each promotion has its own page and rules — read them before opting in. For current codes and our side-by-side comparison, see the Monster Win bonus overview.
Is it worth taking?
Take it if you play slots, you plan to deposit modestly (C$30–C$100) and you'd be playing several hours over the next ten days anyway. The 100 spins per deposit are a genuine extra, and the match gives you more runway.
Skip it if you deposit with Skrill or Neteller, if you mostly play live tables, or if you might want to withdraw within days. In those cases the restrictions cost more than the bonus gives. And whichever you choose, set a deposit limit first — a big match can make a big deposit feel smaller than it is.
Welcome bonus FAQ
Do I need a promo code for the Monster Win welcome bonus?
No. After a qualifying deposit of at least C$30 you activate the welcome promotion in the My Bonus section of your profile. Do it before placing any bet with that deposit.
Which game are the Monster Win free spins on?
All 300 welcome free spins are for Gates of Olympus by Pragmatic Play, credited in batches of 100 with each of the first three deposits.
What is the wagering on the Monster Win bonus?
x35 on the deposit plus the bonus, within 10 days of activation. Winnings from free spins have a separate x40 requirement.
Can I withdraw while the bonus is active?
A withdrawal request before or after activation voids the bonus. Finish the wagering, or cancel the bonus first, then withdraw.
Why didn't my Skrill deposit get the bonus?
Deposits made with Skrill or Neteller don't qualify for the welcome package. Use Interac or a card for the deposit you want matched.
