Bonus Mathematics

Let’s break down the bonus math step by step. Suppose you claim a 100% match bonus up to €200 with a 35x wagering requirement on the bonus amount. You deposit €100, so you receive a €100 bonus. Your total balance becomes €200 (deposit + bonus).
Important: The wagering requirement applies only to the bonus, not the deposit. Formula: Wagering Target = Bonus × Wagering Multiplier = €100 × 35 = €3,500.
You must place bets totaling €3,500 before you can withdraw any winnings from the bonus. Assume you play slots with an RTP of 96%. Your expected loss per €1 wagered is €0.04. Over €3,500, expected loss = €3,500 × 0.04 = €140. Since your bonus is €100, the expected value of the bonus is €100 – €140 = -€40. This means on average you lose €40 by trying to clear the bonus. However, variance can lead to different outcomes. To improve your chances, choose high RTP slots and manage your bet size.
Another example: if the wagering requirement is 40x (bonus + deposit) for a €100 deposit and €100 bonus: wagering target = (€100+€100)×40 = €8,000. With 96% RTP, expected loss = €8,000×0.04 = €320. Since total bonus is €100, expected loss is €220. Always check the terms before claiming.
