Rollover in sports betting means that a bettor must bet before a bonus becomes available. For example, if a book offers a 100% initial deposit bonus of up toR$500 and has a 10x rollover requirement, you'll need to stake a total ofR$5,000 (10 xR$500) before you can redeem the welcome bonus money.

A rollover is a multiple of a deposit that you must bet in order to cash out any winnings from that sportsbook. If you depositR$200 with a 10x rollover bonus, you need to makeR$2,000 worth of bets to ever see that money. It sounds harmless since you likely deposited at that sportsbook to bet, not win once and run.
