Understanding Your Results
Here's what each result means and how it's calculated
Estimated Chance to Win
The percentage chance of coming out ahead after meeting the wagering requirements, based on the RTP and your bonus terms. This is a theoreticol estimate, not a guarantee.
Total Play Amount
Your deposit plus bonus, multiplied by the wagering requirement.
Example:
€100 deposit + €100 bonus = €200
€200 × 35 = €7,000 total play amount
Estimated RTP Loss
The expected amount lost based on the total play amount and game Return to Player (RTP).
Example:
€7,000 × (1 - 0.965) = €245
Why Wagering Requirements Matter
The higher the wagering requirement, the more you need to play through, and the higher the expected loss. Here's how it looks with a €100 deposit, 100% bonus and 96.5% RTP.
| Wagering Requirement | Total Play Amount | Estimated RTP Loss |
|---|---|---|
10x | €2,000 | €70 |
20x | €4,000 | €140 |
35x | €7,000 | €245 |
50x | €10,000 | €350 |
