The wagering requirement: how much turnover really sits behind a bonus
Wagering is the number that decides whether a bonus turns into money or not. The calculator takes the bonus amount and the multiplier and tells you how much turnover is needed, how long that takes at an average stake and how much of that turnover the house edge eats.
The multiplier applies in two different ways and the difference is twofold. "40× bonus" means €4,000 of turnover on a €100 bonus. "40× bonus + deposit" at the same deposit is already €8,000. In the terms it is one word; in the result it is a twofold difference — the wagering page shows where to find that sentence in the text.
What reduces turnover and what quietly grows it
Game weighting is the most frequent surprise. If a slot gives 100% and roulette 10%, then after an hour of roulette a tenth of the turnover has counted. The weighting table is almost always a separate section in the terms.
RTP does not change the required turnover, but it changes its price. €4,000 of turnover at 96% RTP costs an average of €160, at 94% already €240. The RTP calculator shows that difference separately.
The deadline turns a realistic plan into an unrealistic one. Divide the required turnover by the number of days you have — if the result exceeds the amount you would play anyway, the bonus is not for you.
When there is no wagering at all
Some crypto casinos do not give a deposit bonus but pay back as rakeback: the money arrives on the account with no turnover requirement and is withdrawable immediately. Stake, Gamdom, Roobet and Winna work this way — for a regular player that is almost always more profitable than a large welcome bonus. Our cashback offer list compares them side by side, and the bonus calculator shows what the same money would cost as a welcome bonus.
If withdrawal speed is your main criterion, Estonian-licensed houses are covered by kiiredvaljamaksed.ee; for foreign licences it is worth checking the EMTA register to confirm that an Estonian licence really is absent.

Two checks before you take a bonus
First: does the wagering apply to the bonus or to the bonus and the deposit. That one word in the terms doubles the turnover. Second: is there a cap on the win. "Max win 5× bonus" means a big hit gets cut off and the whole calculation has to be done again.
If both are in order and the turnover fits the deadline, the bonus is probably fair. If one of them is bad, no large percentage rescues it. Our bonus list states both lines next to every offer, and the FAQ explains the common traps at greater length.
