Sanspiel is a falling sand game, written with Rust / WebAssembly and ~ 2 million page views monthly. Built by Max Bittker.

Sandspiel uses Rust / Wasm for all of the particle simulation code. This allowed them to get the game running at a smooth 60fps, with a large total "sandbox" size. Whereas, they struggled with performance using other solutions in the past.
