Calculating Your Bonus
Let’s assume a 100% welcome bonus up to €200 with a 40x wagering requirement on the bonus amount. If you deposit €100, you receive €100 bonus, giving you a total of €200 to play with.
Wagering requirement: Bonus amount × Wagering multiplier = €100 × 40 = €4,000. You must wager €4,000 before you can withdraw any winnings from the bonus.
Now consider the game contribution: Slots usually count 100%, table games might count 10% or less. If you play slots only, each €1 bet contributes €1. So you need to place €4,000 in bets.
Expected loss: House edge varies by game. For a slot with 96% RTP, the house edge is 4%. Expected loss = Total wagered × House edge = €4,000 × 0.04 = €160. So from your €200 total, you might expect to lose €160 during wagering, leaving about €40 as potential withdrawable balance (before considering variance).
Formula: Expected value = Bonus amount – (Wagering requirement × House edge). For this example: €100 – (€4,000 × 0.04) = €100 – €160 = -€60. The bonus has negative expected value if you only play high-house-edge games. Choose slots with high RTP (≥97%) to improve outcomes.
