Calculating Your Bonus

Welcome bonuses typically consist of a match percentage on your first deposit plus free spins. For example, a 100% match up to €500 means the casino doubles your deposit, but the bonus amount cannot exceed €500. The bonus is subject to wagering requirements, usually expressed as a multiplier (e.g., 35x).

Important: Wagering requirements apply to the sum of deposit plus bonus, unless stated otherwise.

Example calculation:

  • Deposit: €100
  • Bonus: 100% up to €500 → you receive €100 bonus (since €100 ≤ €500)
  • Total balance: €200 (deposit + bonus)
  • Wagering requirement: 35x (deposit + bonus) = 35 × €200 = €7,000
  • You must place bets totaling €7,000 before any winnings from the bonus become withdrawable.

Game contributions vary. Slots usually count 100%, while table games may count only 10% or less. Effective wagering requirement = (total wagering) / (game weight). For a slot (100% weight), you need to wager €7,000 in real bets. For blackjack (10% weight), you would need to wager €70,000 to clear the bonus.

Free spins winnings also come with their own wagering requirements, often 40x the win amount.
