How to Play
Physics Behind the Simulation
Each pixel follows simple rules — complex behavior emerges from thousands of tiny interactions per frame.
Water simulates pressure and flow using a simplified Navier-Stokes approach, all running in WebAssembly.
Sandspiel uses a machine-learned color model to generate beautiful, organic color schemes for each element.
The full simulation engine is open source (AGPL) — you can study, fork, and extend the physics.
This game is powered by Sandspiel by Max Bittker — a beautiful open-source falling sand simulation engine. The WebAssembly engine runs millions of physics calculations per second right in your browser.
