The wagering requirement (also known as playthrough or rollover) is the most important term in any casino offer. Simply put, it is a multiplier that represents how many times you must bet your bonus funds before they turn into withdrawable cash.
Why do these exist? Without wagering requirements, a player could claim a bonus and immediately withdraw it without ever playing a game. By requiring a certain volume of bets, operators can afford to give away these extra credits while ensuring they are used for their intended purpose: entertainment.
It is vital to check whether the requirement applies to the bonus amount only or to the deposit plus the bonus. The latter significantly increases the amount of betting required to unlock the funds. You can track your progress in the bonus section of your account, where a progress bar or counter typically shows how much more you need to bet. The exact multiplier for any specific offer is always displayed alongside the promotion in your account.
