I built a multiplayer crypto price prediction game using Pyth Network oracles

The author built Price Royale, a free-to-play multiplayer game where players predict whether ETH, BTC, or SOL prices will go up or down within 15–90 seconds, using Pyth Network's Hermes REST API for real-time oracle price feeds. The game features personalized entry prices snapped at the moment of each player's commit, a confidence interval-based score multiplier rewarding predictions during volatile markets, and multiple modes including custom rooms, Quick Royale, and Tournament brackets. The stack uses Node.js, Express, Socket.io, and React with no blockchain or wallet connection required.
