Bonus Rollover EV

Operator bonuses look generous; the wagering requirement decides whether they actually are. This puts a number on it.

e.g. "30x bonus"
Slots 1.0 · Blackjack 0.10 · Live games often 0
Net EV of bonus
$-20.00
Negative — paying for the bonus.
Expected loss to house
$120.00
Across $3000.00 wagered

Notes

  • Most operators run "bonus only" WR; some run "bonus + deposit" — this roughly doubles the work for a 100%-match bonus.
  • Game contribution is the lever that decides whether you can clear the bonus on a low-edge game like blackjack at all. Many operators set blackjack contribution to 0% specifically to prevent this.
  • If net EV is positive, the bonus is theoretically +EV before considering bonus-abuse account closures, max-bet violations, and time. Read the terms.
