Bonus Mathematics
Welcome bonuses often come with wagering requirements. Let’s calculate the expected value (EV) of a typical bonus. For example:
- 100% match bonus up to €100
- Wagering requirement: 35x (bonus + deposit)
- You deposit €100, get €100 bonus → total €200 to wager
- Wagering amount: 35 × (€100 + €100) = 35 × €200 = €7,000
- Assume you play a slot with 96% RTP (house edge 4%)
- Expected loss during wagering: €7,000 × 0.04 = €280
- But you only deposited €100. Your expected net result: €100 (bonus) – €280 = –€180
Thus, the bonus has negative EV unless you consider the free play value. To break even, you’d need an RTP of at least (€100 + €100) / €7,000 = 2.86% house edge, meaning 97.14% RTP. Always check game contributions: slots usually count 100%, table games less.

Insider Advice
For the best RTP, choose slots with 97% or higher, such as Blood Suckers (98%), Starmania (97.87%), or Jackpot 6000 (98.9%). Avoid branded slots like Game of Thrones (95%) and certain progressive jackpots where the RTP drops to 88-92% due to the jackpot contribution. Video poker and blackjack with perfect strategy can offer RTPs over 99%. Always check the game’s paytable before playing.
Use the welcome bonus wisely: focus on high-RTP slots that contribute 100% to wagering. Never chase losses — set a budget and stick to it. Good luck!
