The most you can cash out from the bonus. Leave blank if none.

Bonus value (EV)

−$200

Your bonus minus the expected loss. Below $0 means clearing it costs more than the bonus adds.

On average this bonus costs you $200. Clearing it takes $30,000 in bets, and the expected loss of $1,200 is more than the $1,000.

Your bonus
$1,000Your deposit times the match %, capped at the max bonus.
You have to bet
$30,00030x the rollover base, divided by how much your game counts. This is total bets, not deposits.
Expected loss (average)
$1,200Total bets times what the game keeps, 100% minus 96%. At 96% RTP that is 4 cents per $1 bet, on average.
Break-even rollover
25xThe rollover where the bonus and the expected loss cancel out, so the average value is $0.

A 30x rollover is heavier than this bonus can pay for. Past 25x, the average cost is bigger than the bonus.

These are averages, not guarantees. A short session can swing far up or down; this is the long-run average over the full rollover.

The lowest-rollover bonuses we checked

Lower rollover means fewer bets to clear, so it costs less on average: at 96% slots each 1x costs 4% of the bonus, and 25x uses up all of it. None of these three pays on average, the best case is break-even, and every number here comes from a dated review.

How we calculate it

  • Bonus = deposit x match %, capped at the max bonus.
  • Rollover base = the bonus (bonus only) or deposit + bonus. Total you have to bet = rollover x base, divided by the game contribution %. At 100% it is just rollover x base.
  • Expected loss = total bet x (100% minus RTP). At 96% RTP you lose 4 cents per $1 bet, on average.
  • Bonus value (EV) = bonus minus expected loss. With a max cashout, EV is also capped at max cashout minus deposit. A cap can only make the real figure lower, because it cuts off the biggest payouts.
  • Break-even rollover = (bonus / base) x contribution / (100% minus RTP). Bonus only, 100% slots at 96%: 25x. Deposit + bonus on a 100% match: 12.5x.
  • Example: a $1,000 bonus, 30x on the bonus only, 96% slots. You bet $30,000, the expected loss is $1,200, and EV is -$200. Break-even is 25x.
