Sandboxels

Sandboxels is an open-ended falling-sand sandbox where you place pixels representing materials, plants, animals, and other elements on a canvas.

Choose elements from categories and draw them onto the canvas to experiment, cook food, grow ecosystems, or construct things such as power plants. Materials can flow, burn, melt, spread, and react with one another.

The simulation includes systems such as heat, electricity, density, chemical reactions, and fire spread. Steam features include saving creations and browsing or sharing saves through the Workshop; there is no stated story or fixed end goal.

Players who enjoy Sandboxels often praise the range of elements and the surprising ways materials interact, making it fun to experiment, cook, create ecosystems, and build machines or power plants. Reviewers also appreciate the creative freedom and mod support, and some describe it as a relaxing way to pass the time. A recurring reservation is that the Steam release feels very similar to the free browser version.
