Sandspiel

A relaxing falling-sand sandbox where you paint with sand, water, fire, plants and lava and watch them react.

Sandspiel is a meditative falling-sand physics sandbox built in Rust and WebAssembly. Pick from a palette of elements, brush them onto the canvas, and watch simple rules turn into emergent life: sand piles into dunes, water seeks its level, flames spread across dry plants, lava cools into stone, and steam rises when heat meets water. There are no levels, scores, or timers, just a calm space to experiment. You can build rivers, spark wildfires, grow forests, and flood entire landscapes, then share your creations. It is the perfect low-pressure creative toy to lose a few quiet minutes in.

Tip: use your keyboard arrows / touch to control the game.
