What a wagering requirement actually costs you
After reading this you will know how to turn a bonus multiplier into the real amount of money you have to stake before you can withdraw anything.
What the multiplier means
A wagering requirement is the number of times you must bet an amount before you can withdraw it. It is written as a multiplier, like 20x. That number applies to a specific amount of money, not to your whole balance, so the first thing to check is what the multiplier is attached to.
In the 150% first deposit casino bonus, the wagering is 20x the bonus, and separately 10x on whatever the free spins win. Those are two different pots of money with two different requirements, tracked separately.
Working the example
Deposit €600 into the 150% first deposit casino bonus. At 150%, the bonus credited is €900. The wagering requirement is 20x the bonus, so you need to stake 20 × €900 = €18,000 in total bets before that bonus money can be withdrawn.
That figure is what betting counts, not money spent. If you bet €50 and it comes back as €48, you have still wagered €50 toward the €18,000. The requirement is worked through by the total size of the bets you place, win or lose.
Why the game you play changes the number
Not every bet counts in full. This bonus contributes 100% on slots, meaning a €50 slot bet counts as €50 toward the €18,000. Roulette, blackjack, poker, live casino and Aviator count at 10%, so a €50 bet there only counts as €5. Baccarat counts at 0% — it does not reduce the requirement at all, however much you bet.
This means the €18,000 figure is only accurate if you clear it on slots. Try to clear the same requirement on roulette and you would need to place €180,000 in total bets, because only a tenth of each bet counts. The stated multiplier does not tell you this on its own — the game contribution rates do.
Aviator carries an extra condition here: a bet only counts toward wagering if you cash out at 1.30x or higher. A bet cashed out below that multiplier contributes nothing, regardless of the 10% rate.
When a big bonus means a lot of staking
A large bonus and a high multiplier compound each other. €900 at 20x is €18,000 in required bets — most players depositing €600 do not expect to need to place thirty times that amount in bets before the bonus becomes withdrawable. The bonus size makes the offer look generous; the multiplier is what determines how much play it actually takes to access it.
The 50% casino booster bonus shows the same pattern at a smaller scale: a €200 deposit gives a €100 bonus, wagered at 20x, meaning €2,000 in total bets. Smaller bonus, same multiplier, proportionally smaller target — but the same principle: multiply the bonus you actually receive by the wagering figure to get the real number.
To know what a bonus really costs in play, multiply the bonus amount by the wagering requirement, then check the game contribution rate for whatever you intend to play, because a low rate can multiply that number several times over.
