Understanding wagering requirements is one of the most confusing – and critical – parts of evaluating casino bonuses. A bonus that looks great on the surface can turn into a costly mistake if the wagering requirement is unrealistic or if certain games contribute less to the requirement.
To make it simple, we created a Casino Bonus Wagering Calculator.
Use it to calculate:
- How much you need to wager before you can withdraw
- How different wagering requirements (20x, 35x, 50x…) impact your bankroll
- How game contribution rules affect wagering (100% for slots, 10% for tables, etc.)
- Whether a bonus is worth taking — or better skipped

Figure out exactly how much you need to wager before a withdrawal is allowed — and how game contribution affects the total.
How Casino Wagering Requirements Work
Every casino bonus comes with something called a wagering requirement (sometimes called playthrough or rollover). It tells you how much money you must wager before you can withdraw your winnings.
Example:
A €200 bonus with a 35x wagering requirement means:
€200 × 35 = €7,000 must be wagered
Many players miss that some casinos apply wagering not just to the bonus — but to deposit + bonus combined.
Example:
Deposit €100 + €100 bonus = €200
Wagering = 35×
€200 × 35 = €7,000 total wagering
That’s double the effort for the same bonus.
Game Contribution (This Is Where Casinos “Hide” the Rules)
Not all games contribute equally to wagering:
| Game Type | Contribution |
|---|---|
| Slots | 100% (most casinos) |
| Roulette | 10–20% |
| Blackjack | 10% (sometimes 0%) |
| Live Casino | Often excluded |
Which means:
If you play roulette with only 10% contribution, you must wager 10× more than with slots.
No Deposit Bonuses: Watch the Max Cashout Rule
No-deposit bonuses usually have limits:
- Low bonus amount (e.g., €10–€25)
- Max cashout cap (e.g., €100)
This is why a small no-deposit bonus can still require thousands in wagering.
Free Spins Are Not Free
Free spins convert to bonus money based on the slot’s RTP.
Example:
- 100 free spins
- €0.20 per spin
- 96% RTP (expected value)
Expected win = €19.20
The calculator handles this automatically.
Should You Take a Bonus or Play Without One?
Here’s a simple rule:
If you enjoy long play sessions → take the bonus
If you want fast cashout flexibility → skip the bonus
Bonuses increase playing time.
No bonuses increase withdrawal freedom.
