How 50% slot rakeback is actually calculated
Rakeback is the casino's gross gaming revenue (GGR) returned to the player. On a slot, GGR equals total wagered minus total returned. If you spin $1,000 and the slot pays back $850, the casino's GGR is $150. Duel returns 50% of that — $75 — directly to your wallet, every minute as it accrues. There is no deposit qualifier, no time window, no minimum bet, and no maximum cap on the rakeback amount. Unlike a deposit-match bonus, the funds are unlocked from the moment they land.
