Bonus Mathematics
Let’s break down a typical welcome bonus step by step. Example: 100% match bonus up to €500 with a 35x wagering requirement on the bonus amount.
Scenario: You deposit €200 and receive a €200 bonus. Your total balance = €400.
Wagering requirement: 35 x €200 = €7,000. You must place bets totaling €7,000 before withdrawing any winnings from the bonus.
Game contribution: Slots usually count 100%, table games may count 10% or less. If you only play slots, 100% of each bet counts. To clear the wagering with €200 bonus money, you need to wager €7,000. With an average RTP of 96%, your expected loss on that wagering is 4% x €7,000 = €280. Since you only have €200 bonus, you are likely to lose the bonus before clearing it unless you are lucky.
Max bet rule: Most bonuses cap max bet at €5 per spin. Exceeding that voids the bonus. Typical slot spin costs €0.20–€5. If you bet €5 per spin, you need 1,400 spins (€7,000 / €5). At 3 seconds per spin, that’s about 70 minutes of continuous play.
Expected value calculation: EV = (bonus amount) – (wagering requirement * house edge). House edge = 1 – RTP. For 96% RTP, house edge = 4%. So EV = €200 – (€7,000 * 0.04) = €200 – €280 = -€80. Negative EV means the bonus is unfavorable on average, but due to variance, some players win. Always read terms: some casinos offer ‘low wagering’ bonuses with better EV.
