One of the key factors that determine the difficulty of wagering a casino bonus is the wagering requirement. This is the number of times a player must bet their bonus funds before they can withdraw their winnings. Wagering requirements can range from as low as 10x to as high as 50x or more, depending on the bonus and the casino. For example, a welcome bonus with a 30x wagering requirement means that a player must bet their bonus funds 30 times before they can withdraw their winnings.
