Sand Game JS is a fast, free and open-source falling-sand game for desktop & mobile browsers. It allows players to experiment with various elements, such as sand, soil, water and fire. With grass and trees growing on soil, and other natural processes, Sand Game JS offers a unique experience. It is primarily tested on Google Chrome and Google Chrome for Android.

Browser-based successor to Sand Game 2, which was originally developed in Java (JavaFX).

  • Alternatively ctrl + shift + space will run the specified number of iterations – at once, without rendering and delays.
