FAQ

Is 10/7 Double Bonus really over 100%?

Yes — 100.1725% with optimal play, computed by exact enumeration. The catch: the strategy is genuinely hard (two pair pays only 1), mistakes are expensive, and true 10/7 machines are scarce. 9/7 returns 99.1065% and the common 9/6 just 97.8062%.

Why does two pair only pay 1 in Double Bonus?

That's where the quad money comes from. It also warps strategy: some two-pair and kicker decisions flip versus Jacks or Better — drill them in the trainer before playing for money.

What quads pay in Double Bonus?

Aces 160, 2s–4s 80, 5s–kings 50 (per coin). No kicker bonuses — that's Double DOUBLE Bonus. If your machine shows 400 for aces with a kicker, you're on DDB and the strategy differs again.

Should a beginner play Double Bonus?

Learn Jacks or Better first. DB's edge only materializes with near-perfect play; with chart-level accuracy you're better off on 9/6 JoB or 8/5 Bonus until the trainer says your DB accuracy clears 99%.
