A five times rollover refers to the wagering requirement that some betting sites or online casinos may impose on bonuses or promotional offers. It means that you need to bet or wager the bonus amount five times before you can withdraw any winnings or the bonus itself. For example, if you receive a $100 bonus with a five times rollover, you would need to place bets worth $500 ($100 x 5) to meet the requirement. Keep in mind that not all bonuses may have a rollover requirement, and the specific terms and conditions may vary depending on the site or casino.
