What is rollover in bonus terms?
Rollover is another term for wagering requirement — the number of times you must wager a bonus (or bonus plus deposit) before any associated winnings become withdrawable. A 30x rollover on £100 means you need to place £3,000 in total bets.
Rollover calculations
Most casinos calculate rollover on the bonus amount only. Some calculate it on bonus plus deposit (more restrictive). A 30x rollover on a £100 bonus = £3,000 in total wagers needed. A 30x rollover on bonus + £100 deposit = £6,000 needed. Always check the calculation basis. If you wager £500 on blackjack at 10% contribution, only £50 counts toward the rollover.
What’s a good rollover?
30x-35x on bonus only is industry standard and workable for most players. Under 20x is favorable. Above 50x is high and may not be worth claiming. Rollover combined with a short time window (7 days to clear 40x on a large bonus) can make bonuses mathematically unreachable for lower-stakes players. Calculate the required daily wagering before accepting: divide total rollover by the number of days allowed.
