How it works
The formula
Turnover = bonus×WR. Expected cost = turnover×(1−RTP). Bonus EV = bonus − cost.
Example: 100 bonus ×35 @96% RTP → 3500 turnover, ~140 cost → EV ≈ −40.
FAQ
Questions
Are casino bonuses worth it?
Only when bonus value exceeds the expected wagering cost — often not.
What counts toward wagering?
Depends on game weighting; slots usually 100%, table games far less.
