In some cases, players may also be required to make a deposit before they can claim a bonus. The requirements will specify the amount that must be wagered, as well as the games that the bonus can be used on. Wagering requirements are typically imposed when players claim a bonus, such as a welcome bonus or a reload bonus. By imposing wagering requirements, the casinos and sportsbooks ensure that players will play the games and potentially lose some of the bonus money before they can withdraw their winnings. The purpose of wagering requirements is to protect online casinos and sportsbooks from players who would simply take the bonus and withdraw the money without actually playing any games. These requirements specify the amount of money that players must wager before they can withdraw any winnings earned from a casino bonus. Wagering requirements, also known as 'playthrough' or 'rollover' requirements, are a set of terms and conditions that online casinos and sportsbooks impose on bonuses and promotions.
