How Rock Paper Scissors Works
Rock Paper Scissors is the platform's player-versus-player original. Instead of betting against the house, you face another real player in a best-of match. You commit your move cryptographically so neither side can peek, the moves reveal together, and the winner takes the pot.
What makes it special is that Duel takes no rake from the pot. That is why the return is a literal 100%: it is a straight contest between two people with nothing skimmed off the top. It is also a genuinely social game, the kind of low-stakes duel you can play for ten cents just for the fun of it.

Provably Fair
Every Duel Original, including Rock Paper Scissors, 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 Rock Paper Scissors. 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.
