How This Works
A “100% up to $500” bonus sounds great, but wagering requirements mean you need to bet the bonus amount many times before withdrawing. During that wagering, the house edge eats into your balance. This calculator shows what the bonus is actually worth after accounting for expected losses. Formula: Real Value = Bonus − (Total Wager × House Edge).
