Wagering Requirements (Playthrough) is the amount that must be wagered (put at risk) before you may cashout any winnings resulting from a bonus offer. It is a multiple of your deposit or a multiple of your deposit plus the bonus. For example, "20x deposit" on a deposit of $100 means playthrough is $2000. "20x deposit + bonus wagering" on a deposit of $100 with a bonus of $100 means playthroucih is $4000.
