If you claim a Bonus, you must wager it. For example, if you claim a 100% bonus and deposit 10€, you get 10€ on top, and you can play with 20€. If the bonus terms state that you have to wager the deposit + bonus (D + B) 35 times, this means that you have to wager 700€ (deposit € 10 + bonus € 10 x 35). This means that you have to do for example 700x an 1 € spin on a Slot, before you can cashout your winnings. Please always have a look at the bonus conditions before claiming a bonus!
