Bonus Math
The welcome bonus typically offers a 100% match up to €500 plus 200 free spins. Let’s break down the wagering requirements and expected value.
Example calculation:
Deposit: €100
Bonus: €100 (100% up to €500)
Free spins: 200 spins at €0.10 each = €20 total.
Wagering requirement: 35x (bonus + deposit) = 35 × (€100 + €100) = €7,000
Game contribution: Slots 100%, table games 10%.
If you play only slots, you need to wager €7,000 before withdrawing.
House edge assumption: 4% on average slot RTP 96%.
Expected loss during wagering: €7,000 × 0.04 = €280
Your starting balance: €100 deposit + €100 bonus + €20 free spins (winnings subject to separate wagering) = €220
If free spins winnings also have 35x on the win: assume €10 win from spins → €10 × 35 = €350 more wagering.
Total wagering: €7,000 + €350 = €7,350
Expected loss: €7,350 × 0.04 = €294
Net expected value after wagering: €220 – €294 = –€74 (negative). So the bonus is only valuable if you get lucky. Always read the terms.
