A physical sandbox to experiment, create and observe

Stardust Sandbox  is a creative sandbox simulation inspired by classic falling-sand games. The game provides a free, experimental environment where each element follows its own physical rules, allowing you to build structures, trigger reactions, and observe emergent behaviors naturally.

Total freedom, no pressure

You decide how to play.

Create complex systems, test specific interactions, set up simple scenarios, or simply relax and watch the world react to your actions. Stardust Sandbox adapts to players who enjoy deep experimentation as well as those who prefer a contemplative experience.

Every session is different — small changes can produce completely unexpected results.
