Full-path span including origin
A ball makes twelve independent fair left/right steps, changing signed position by−1 or+1. Score is maximum position minus minimum position over the whole path, including initialzero. Score ranges 1–12; the origin counts in extrema.
Examples of spans 1 and 12
Alternating left/right stays between−1 and 0, scoring 1. Twelveleft steps reach−12 from 0, scoring 12. A path finishingzero can have a larger span than 1; endpoint alone is insufficient.
Weights and gross payouts
Soft/Medium/Bold use powers 1/2/3. Gross return=captured stake×0.96×(score+1)^power/meanWeight. Each mean enumerates all 4096 equally likely paths for that power. Low span may return less than stake; gross multipliers include stake.
Six captured balls
Up to six simultaneous balls each deduct and capture their own stake and mode. While any runs, stake/mode/refill are locked; more drops remain possible below 6 and with enough coins. No cashout orper bounce charge.
Expected return
Exact unrounded expected return 96% all three modes, verified by all 4096 paths. Fractional carry avoids repeated flooring loss. Powers change payout variation, not path probabilities. No finite-session result is guaranteed.
Wallet and unfinished balls
Settled wallet and fractional carry persist in localStorage. Reload ends unfinished balls without refund; controls return stake 20/Soft. Idle balance below 10 can be restored to 1000, preserving carry; refill does not add 1000.
