It's good to be lucky, but sometimes you don't always win. That's why 4Grinz Bitcoin Casino gives you Coin Back - a 10% or more refund on lost play, depending on your player status.


• Coin Back is based on your weekly gross gaming revenue (GGR) not related to bonuses, coupons, or free spin winnings.
• Premium Members start with 10% Coin Back weekly. Joy Luck Club and VIPs earn more depending on their player status.
• Each Coin Back period begins Thursday at 00:01 and ends 00:00 the next Thursday, with Coin Back paid on (Friday).
• We start with each player's GGR (gross gaming revenue) to calcuate Coin Back, then subtract bonuses, deposits associated with bonuses, coupons, and the value of free spins (if applicable).
• There is no limit to how often you can receive Coin Back.
