Wagering, weighting, and the bonus EV
Wagering requirements convert a bonus from advertised money into pending money. A 35× wagering on a €100 bonus means €3,500 of turnover has to flow through eligible games before the balance becomes withdrawable. If wagering is applied to deposit plus bonus, the requirement doubles when the deposit equals the bonus — the same headline rate, twice the work.
Game weighting decides how much of that turnover the casino counts. Slots usually count at 100%, table games at 10%, live tables sometimes at 0%. A €1 bet on roulette at 20% weighting contributes €0.20 to the requirement; you wager five times as much to make progress at the same rate. We compute the effective turnover — the actual euros you have to push through your chosen game category — not the brochure figure.
The expected value of the bonus is the bonus minus the expected loss while clearing it. Push €3,500 through a 96% RTP game and you give back roughly €140 in house edge. A €100 bonus that costs €140 to clear is a negative-EV offer, no matter how loud the headline. We surface this number directly so you can decide whether to claim or pass.
