How Plinko Works
Plinko is hypnotic. You drop a ball from the top of a 16-pin board and watch it bounce left and right until it lands in a slot at the bottom. The outcome follows a binomial distribution, so the centre slots hit often for small multipliers and the edges hit rarely for the big ones.
You control the shape of the risk before you drop. Higher risk stretches the payout table so the edges pay huge and the middle pays under 1x; lower risk flattens it. With no house edge baked in, the expected value stays at break-even whichever profile you pick, so it comes down to how much variance you want.

Provably Fair
Every Duel Original, including Plinko, is provably fair through a dual-seed system. Before a round, the server generates a seed, hashes it and shows you the hash. You add your own client seed, and a nonce counts each bet. Those values run through HMAC-SHA256 to produce the result, and once the round ends the server reveals the original seed so you can re-run the hash and confirm nothing changed after you bet.
You never have to trust Duel on Plinko. The dual-seed commitment means the outcome is locked before your bet and revealed for verification afterwards, so the published return reflects real, checkable odds rather than a promise.
