How This Works
A 40x wagering requirement on a $100 bonus means you must wager $4,000 before you can withdraw. If you play slots with a 5% house edge, you will lose an expected $200 on those wagers. That means the $100 bonus is actually worth $0 in expectation.
Lower wagering requirements and lower house edge games preserve more of the bonus value. A 20x requirement on crash (1% edge) means wagering $2,000 with an expected loss of $20, keeping $80 of the $100 bonus.
