Our cashback offer is based on the net losses from all slots bets made with real money. Every Thursday morning, you will receive 10% of your net losses back. The cashback is calculated from your gameplay during the week, from Thursday to Thursday, and there are no wagering requirements attached.
Please note that cashback is not applicable to bets made on Live Casino, Table Games, or Card Games. This means that any bets placed on Blackjack, Roulette, Poker, Baccarat, or any other live casino games will not qualify for the offer.

But if you are a German player, the cashback bonus is calculated based on your total deposit amount minus your total withdrawal amount (including outstanding amounts) and your account balance for the specified period.
