Pythian Peso Snake
Team: @totti1317 · Submitted: March 15, 2026
Pythian Peso Snake is a browser based Snake game where players eat the Pythian Pesos to score points. Every food placement uses real Pyth Entropy, the full commit-reveal protocol via Fortuna - making each spawn position cryptographically verifiable. It’s a fun, demo of what provably fair randomness looks like in a game.
What It Does
Bringing in the nostalgia of the classic Nokia 1100 Snake game with a twist: every time the snake eats a Pythian Peso (a “PP”), the next food position is determined using the real Pyth Entropy commit-reveal protocol, not just Math.random(). The user contributes a secret, Pyth’s Fortuna service reveals its pre-committed value, and the two are combined via SHA-256 — exactly matching the on-chain contract logic. A live sidebar panel shows the sequence number, user seed, provider seed, and final hash for every draw.
