The wagering requirement (also known as playthrough or rollover) is the most critical part of any bonus. It is a multiplier that determines how much you must bet before bonus funds and their resulting winnings can be withdrawn as cash.
Operators implement these requirements to prevent "bonus abuse," where a player claims a bonus and immediately withdraws it. Without these rules, the platform could not offer substantial bonuses. For example, if a requirement applies only to the bonus amount, you bet that specific sum multiplied by the requirement. If it applies to "Deposit + Bonus," the total amount to wager is significantly higher.
You can track your progress in your account settings, where a counter typically shows how much more you need to bet. The exact multiplier for any given offer is always displayed clearly within the promotional details before you click "Claim."
