10/7 Double Bonus strategy: 36 lines, over 100% return
Full-pay Double Bonus returns 100.17% with perfect play — the famous player-edge game. This chart gets a human to ≈100.160%, measurably above the 34-line chart most books print.
What's different about this chart
Double Bonus pays two pair only even money, which drains the follow-up value of a high pair — enough that a Q-J-10 or K-Q-J royal draw beats an overlapping pair. We verified this line across all 3,456 relevant hands with an exact solver; published charts don’t have it. The full study, including the tweaks that failed, is here.
Strategy differences that matter vs Jacks or Better
Chase quads harder (three aces pay 240 per coin at max bet), respect straight and flush draws more, and value two pair less — the chart encodes all of it in 36 ordered lines with hover explanations for the tricky ones (straight-flush draw types, inside-straight high-card counts). Start from the 9/6 JoB chart if you’re new; this game is higher variance and less forgiving.
