How the calculator works
Duel pays rakeback as a percentage of the casino's theoretical take (house edge × wager). The calculator below uses your inputs to compute the cash you would receive at standard slot RTP (96% by default), Duel Originals (100% RTP, the 5% rakeback applies to losing variance), and Duel Blackjack (0.5% edge offset by 80% rakeback).
Calculate your monthly rakeback
How rakeback math works
Slots: At 96% RTP, the house's theoretical take is 4% of every dollar wagered. Duel returns 50% of that as cash. $2,000 monthly slot wager → $40 house take → $20 rakeback.
Originals: At 100% RTP, expected loss is zero on average. The 5% rakeback applies to variance-based losing rounds. Effective return: marginally positive EV.
Duel Blackjack: 0.5% house edge × 80% rakeback = 0.1% effective edge. The lowest-edge blackjack product online.
