Answer Capsule
Pyth Roulette is a BTC price betting game where players wager odd/even on the last two digits of Bitcoin’s dollar price. Pyth Entropy generates a verifiable random countdown on OP Sepolia, and when it hits zero, Pyth Price Feeds reveal the live BTC/USD price to determine the outcome. Both Pyth products work together — Entropy controls the timing, Price Feeds deliver the result.
What It Does
Pyth Roulette turns two Pyth primitives into a playable game. Players bet whether the last two digits of BTC’s whole-dollar price will be odd or even. Pyth Entropy picks a random countdown (3-30 seconds) via on-chain verifiable randomness, and when the timer expires, Pyth Hermes streams the live price that decides the outcome.
