Falling Cubes

Falling Cubes is a 3D sandbox where you experiment with physics and chemistry to unlock over 200 cube types. You shape the simulation with tools, change the environment and watch cubes interact, transform and trigger chain reactions.

Experiment with cubes

Paint cube types into the world, adjust the temperature and create pockets of pressure. Cubes fall and stack under gravity; pressure pushes, pulls and crushes them, while temperature spreads to melt or freeze them. Acids and bases dissolve their surroundings, biology rots and metals rust over time. Cubes can also crack, grow, decompose, burn and explode, as they fall, flow, launch and transform in response to the environment and your actions.

You can apply pressure or temperature, or combine chemicals, to unlock each cube type. The simulation includes hundreds of interacting materials, including explosives and volatile compounds, reactive metals and oxidizing elements, fuels, gases, liquids and structural solids. Its systems react to your actions to create emergent gameplay.

Shape the simulation

Use the available tools to create environments, simulate natural processes or cause widespread destruction. The game uses ray-traced voxels. Music plays at the beginning and occasionally later.
