Wagering Requirements Explained: How Casino Bonuses Really Work 2026
A 200% bonus sounds like free money until you read the wagering requirement, and then it sounds like homework. The wagering requirement is the number that decides whether a bonus is genuinely good or just bait. It is the amount you have to bet before you can withdraw bonus winnings, and it is the single most important term on any offer. This guide shows you how to read it and judge a bonus honestly.
We cover what the requirement means, how to calculate it with a worked example, why crash games may count differently, and how to spot a fair offer from a trap. No spin, just the math behind the marketing.

Key Takeaways
- Wagering requirements set how much you must bet before withdrawing bonus winnings.
- A 40x requirement on a $100 bonus means betting $4,000 in total first.
- Lower is better. A 25x bonus is far easier to clear than a 50x one.
- Game weighting matters, and crash games may count fully, partly, or not at all toward it.
- The math, not the headline, decides whether a bonus is worth claiming.
What Is a Wagering Requirement?
A wagering requirement, sometimes called a rollover, is the amount you must bet before any winnings from a bonus become withdrawable. It is written as a multiplier, like 40x. That number tells you how many times you have to wager the bonus, or the bonus plus deposit, before the casino lets you cash out what you won with it.
It exists because casinos do not give away money for nothing. The bonus gets you playing, and the wagering requirement makes sure you bet enough that the house edge does its work before you can withdraw. Understanding it turns a bonus from a guessing game into a calculation. Our Aviator bonus guide applies this to real offers.
How to Calculate a Wagering Requirement
The math is simple once you see it done. Multiply the bonus amount by the wagering number, and that is the total you must bet. Always check whether the requirement applies to the bonus alone or the bonus plus your deposit, since that changes the figure.
Example
You deposit $100 and claim a 100% bonus, giving you a $100 bonus. The offer has 40x wagering on the bonus. That means 40 times $100, so you must bet $4,000 in total before withdrawing bonus winnings. If the requirement applied to bonus plus deposit, it would be 40 times $200, or $8,000.
Now apply it to a big headline offer. A 200% bonus up to $10,000 with 40x wagering, if fully claimed, means betting up to $400,000 to clear it. That is why the headline size is not the whole story, and why a smaller bonus with lower wagering is often the better deal.
Why Game Weighting Changes Everything
Not every game counts the same toward wagering, and this catches a lot of crash players out. Casinos assign each game category a weighting, the percentage of your bets that counts toward the requirement. Slots usually count 100%. Table games often count far less, sometimes 10% or even nothing. Crash games sit in a gray area that varies widely by casino.
At some sites, Aviator and other crash games count fully toward wagering. At others, they count partially, or are excluded from bonus play entirely. This matters enormously, because if your favorite game counts at 20%, you have to bet five times as much to clear the same requirement. Always check the game weighting in the bonus terms before you assume your crash play counts.
Important
Read the bonus terms for three things: the wagering multiplier, whether it applies to bonus or bonus plus deposit, and the game weighting for crash games. If crash games are excluded or count at a low percentage, a bonus that looks great for Aviator play may be nearly impossible to clear.
How to Judge if a Bonus Is Worth It
Put the pieces together and a bonus reveals itself quickly. A fair offer has a reasonable size, a wagering requirement around 25x to 40x, applies to the bonus alone, and lets crash games count fully. A trap has a huge headline number, 50x or higher wagering, applies to bonus plus deposit, and excludes or under-weights the games you actually want to play.
There is also a simple alternative worth knowing. Some sites, like Stake, skip match bonuses entirely in favor of VIP rakeback, which returns a percentage of your wagering with no rollover to clear. For high-volume players, that can be worth more than a big bonus with heavy wagering. The casinos below show a range of both approaches.

Final Word on Wagering Requirements
The wagering requirement is where a bonus stops being marketing and starts being math. Calculate the total you would have to bet, check whether it applies to bonus or bonus plus deposit, and confirm your crash games actually count. A modest bonus with low wagering and full crash weighting beats a giant one you can never clear. Read the terms, do the multiplication, and you will never be fooled by a headline again. Our Aviator bonus guide ranks real offers on these terms.
Wagering Requirements FAQs
It means you must bet 40 times the bonus amount before withdrawing bonus winnings. On a $100 bonus, that is $4,000 in total bets. Check whether the 40x applies to the bonus alone or the bonus plus your deposit, since that doubles the figure.
It depends on the casino. Some count Aviator and other crash games fully, some count them partially, and some exclude them from bonus play entirely. Always check the game weighting in the bonus terms before assuming your crash bets count.
No. A large bonus with high wagering can be harder to clear than a small one with low wagering. The size, the rollover, what it applies to, and the game weighting together decide the real value, not the headline number alone.
