Understanding Wagering Requirements

Wagering requirements determine how many times you must play through a bonus before withdrawing winnings. For example, a $100 bonus with a 15x wagering requirement means you must wager $1,500 before cashing out. Different games contribute differently; slots often count 100%, while table games like blackjack may contribute only 10-20%. Low wagering requirements (1x-15x) are player-friendly, making it easier to convert bonuses into real money. High requirements (30x+) can be tough for casual players. Always read the fine print to avoid surprises.
