Whether you are a returning veteran or a curious newcomer, here is everything you need to know about the latest evolution of this pixel-art physics playground. For the uninitiated, Sandspiel 2 is a falling-sand physics simulation created by Max Bittker. Unlike its predecessor, which was a charming but limited experiment, Sandspiel 2 introduced a vibrant, cellular-automata-based ecosystem where thousands of particles interact in real-time.

Whether you want to build a serene aquatic ecosystem, a pixel-art CPU, or just watch Fire burn things in a satisfying way, the updated version delivers. It’s free, it’s in your browser, and it’s more capable than ever.
