3v3 reinforcement-learning football, fully in your browser.
⭐ If you like this project, please give it a star — it means the world!
▶ Play Now — zero install, zero backend, just open and watch the ducks go.
Six robot ducks. One neon arena. A ball. All the physics and AI run natively in your browser — MuJoCo compiled to WebAssembly simulates every joint at 50 Hz, while 9 ONNX neural-network policies (trained with reinforcement learning) make each duck walk, kick, and score on its own.
No servers. No pre-rendered video. Your browser is the game engine.
- 🆓 Fully open source — MIT license, fork it, learn from it, ship it
- 📦 Zero backend — pure static site, deployable to any CDN or container host
- 🦆 Browser-native physics — MuJoCo WASM rigid-body simulation at 50 Hz
- 🧠 Real RL policies — 9 neural networks running via ONNX Runtime Web
- 🌐 WebRTC multiplayer ghosts — P2P duck sync with no server in between
- 🎓 A learning goldmine — reinforcement learning, WebAssembly, 3D game dev, P2P networking, all in one small codebase
