Bonus Mathematics
Understanding the math behind bonuses helps you make informed decisions. Consider a typical welcome offer: 100% match bonus up to €200 with a 35x wagering requirement on deposit plus bonus, and 50 free spins.
Example calculation:
Deposit: €100
Bonus: €100 (100% match)
Total balance: €200
Wagering requirement: (€100 deposit + €100 bonus) × 35 = €7,000
Game contribution: Slots typically count 100%; table games may count 10% or less.
Using a slot with 96% RTP (house edge 4%):
Expected loss while wagering €7,000 = €7,000 × 0.04 = €280
Since you wagered €7,000, you expect to retain €7,000 − €280 = €6,720 as winnings (including original bonus money). Net expected value from the bonus: (€6,720 − €200 initial balance) roughly = €6,520, but you must subtract the deposit? Actually, expected return: €7,000 × 0.96 = €6,720, so you end with €6,720. Since you deposited €100, your net profit expectation is €6,720 − €100 = €6,620, but that includes the bonus money. More practically, the bonus has a positive expected value only if the wagering requirement is low and RTP high. Here, the bonus adds €100, but you risk €100. The expected value of the bonus alone: (bonus amount) − (expected loss from wagering) = €100 − (marginal loss)? Let’s simplify: The wagering requirement is 35x, so you need to bet 35 times the bonus. For a €100 bonus, you must wager €3,500 (if only bonus, but here it’s deposit+bonus). Actually wagering on deposit+bonus is worse. The player’s expected loss from wagering €7,000 at 96% RTP is €280. So the net gain from the bonus after wagering is €200 (initial) − €280 = −€80, meaning you expect to lose €80 overall. That’s why many bonuses are not profitable unless you get high RTP games. Always calculate before claiming.
Free spins: 50 spins at €0.10 each = €5 total bet. With 96% RTP, expected win €4.80. Wagering on winnings (e.g., 40x) applies.
