Calculating Your Bonus

Onlywin Casino offers a welcome bonus that typically matches your first deposit by up to 100% plus free spins. Let’s calculate the effective bonus value step by step.

Example scenario: You deposit €100 and receive a 100% match bonus up to €500, plus 50 free spins on a specific slot. The bonus funds are separate from your cash balance and come with a wagering requirement of 35x (bonus amount).

Formula for total playthrough:
Playthrough = Bonus Amount × Wagering Requirement
If bonus = €100, then Playthrough = €100 × 35 = €3,500.

Each game contributes differently to the wagering requirement. Slots usually count 100%, table games like blackjack count 10%, and roulette may count 0% (check terms).

To calculate the expected value of the bonus, consider the house edge of the games you play. Example: If you play a slot with 96% RTP (house edge 4%), the expected loss over €3,500 wagered is €3,500 × 4% = €140. Since your bonus is €100, the expected net result is negative (you’ll likely lose the bonus before clearing). But free spins add extra value: suppose 50 spins at €0.20 each = total bet €10, and with same RTP, expected return is €9.60. The total expected loss from spins is €0.40, negligible.

Thus, bonus hunting requires careful game selection. Stick to high RTP slots (97%+) and avoid games with low contribution to increase your chances of meeting playthrough.

Tip: Onlywin Casino tiers the bonus — for deposits over €500, you might get 50% match; always check the exact terms in the promotions page.
