Calculating Your Bonus

Let’s break down the math behind a typical welcome bonus. For example, a 100% match up to €200 with a 35x wagering requirement on the bonus amount.

If you deposit €100, you receive €100 bonus, giving you a total balance of €200. The wagering requirement is 35 × €100 = €3,500. This means you must place bets totaling €3,500 before you can withdraw any winnings from the bonus.

Assuming you play a slot with an RTP of 97.5% (house edge 2.5%), the expected loss over the wagering is €3,500 × 0.025 = €87.50. Your expected value after completing wagering is €200 – €87.50 = €112.50, but this is before considering any contribution differences. Note that not all games contribute equally; slots typically contribute 100%, while table games may contribute less.

Formula: Wagering Requirement = Bonus Amount × Multiplier. Expected Loss = Wagering Requirement × House Edge. Expected Value = (Deposit + Bonus) – Expected Loss.
