Session limits
This demo is restricted to adults 18+ and uses coins without cash value or prizes. Set session time and virtual-coin limits before playing, then stop at those limits. Raising a stake to recover losses does not improve expectation. If playing affects responsibilities or becomes hard to control, stop and seek suitable independently verified local support.
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.
Own-site terms

Frequently asked questions
Independent query guide?
This independent KM 12 query guide offers its original Range Marker Plinko. No external operator identity, domains, licence, apps, payments or support are authenticated. No operator account or commercial link is provided.
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.
