A “$100 bonus” is rarely worth $100. The wagering requirement (rollover) forces you to bet the bonus many times over, and the game's house edge eats a slice of every wager. Enter the terms to see what the bonus is actually worth before you deposit.
Rollover applies to:
Total to wager
$3,000
Expected cost
$120.00
Real bonus value
-$20.00
Value retained
-20%
Not worth it at this house edge — the wagering requirement costs more than the bonus is worth. Try a lower-edge game (e.g. blackjack) or skip it.
How it works
- Total to wager = bonus (or deposit + bonus) × the rollover multiple. A $100 bonus at 30× = $3,000 of bets.
- Expected cost = total wagered × house edge. Lower-edge games (blackjack ~0.5%) clear far cheaper than slots (~4%) — but most bonuses restrict the low-edge games or count them at a reduced rate.
- Real value = bonus − expected cost. If it's negative, the bonus costs more to clear than it's worth.
- Always read which games count toward wagering and at what weighting — it's the fine print that decides whether a bonus is good. Compare operators in our crypto casino reviews.
