Bonus Mathematics
Casino Onlywin offers a typical welcome bonus of 100% up to €200 plus 50 free spins. Let’s calculate the effective value after wagering.
Important: Wagering requirements apply to the bonus amount plus the deposit amount. Assuming a 35x wagering requirement on deposit + bonus:
- Deposit: €100
- Bonus: €100 (100% match)
- Total to wager: (€100 + €100) × 35 = €7,000
- RTP of slots: 96% average → expected loss per €1 wagered = €0.04
- Total expected loss: 7,000 × 0.04 = €280
- But you have €200 to play with initially. Expected net loss = €280 – €200 = €80. So you are likely to lose €80 of your own money before releasing the bonus.
If you wager efficiently on high RTP games (98%), expected loss per €1 = €0.02 → total expected loss = €140 → net loss = €140 – €200 = -€60? Wait, that’s a positive expected value. Actually: You deposit €100, get €200 total. Expected loss on wagering: 7,000 × 0.02 = €140. So expected remaining balance after wagering = €200 – €140 = €60. So you end with €60, a net loss of €40 from your deposit. Better but still negative.
Free spins: 50 spins at €0.10 each = €5 wagering-free? Usually winnings from free spins have wagering too, say 40x on winnings. Assume €2.50 winnings average → need to wager €100 → expected loss €2 → net small. Bonus math shows the house edge is real.
