About Sandboxels Game

The free falling-sand simulator game for curious minds, creative builders, and physics enthusiasts. Learn about mods, recipes, the wiki, and the community.

What is Sandboxels?

Sandboxels is a falling-sand game — a type of particle simulation where every pixel on the screen represents an element with its own physical properties. Sand falls, water flows, fire spreads, plants grow, and hundreds of chemical reactions happen in real time.

Unlike traditional games, there are no goals or objectives. Sandboxels is a creative sandbox where you experiment freely. Mix lava and water to create stone. Grow forests and set them ablaze. Build elaborate machines with pistons and conveyor belts. The only limit is your imagination.

The simulator runs entirely in your browser — no downloads, no accounts, no cost. Just open the page and start creating.
