Understanding Your Results

Here's what each result means and how it's calculated

Estimated Chance to Win

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

Total Play Amount

Your deposit plus bonus, multiplied by the wagering requirement.
Example:
$10 deposit + $10 bonus = $200
$20 × 35 = $700 total play amount
Estimated RTP Loss

Estimated RTP Loss

The expected amount lost based on the total play amount and Game Return to player - RTP.
Example:
$700 x (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.
