A wagering requirement (a play-through requirement, wager) is what you need to deal with when you have any bonus credits in your account. As you probably know, they are not real money, and nobody can withdraw them. A wagering requirement indicates how many times these credits have to be played through before they become real money ready for withdrawal. To calculate the number of plays-through, we need to multiply the number of credits by the wager coefficient. Let’s say you claimed a $20 no deposit bonus with a wagering requirement = 15x. You will have to play through the amount of $300 ($20x15), and any winnings left after that will be yours to withdraw.
