Falling Cubes

Inspired by classic falling sand simulations, Falling Cubes is a 3D sandbox where you experiment through physics and chemistry to unlock over 200 unique cube types.
Collide cubes and unleash chain reactions. Crack, grow, decompose, burn, freeze, melt, and explode. Watch as your cubes fall, flow, launch, and transform in response to their environment and every change you make.
Every experiment brings you closer to unlocking each and every cube.
Shape your simulation using a variety of tools. Paint cube types into the world, raise or lower the temperature, and create pockets of pressure to see how your cubes react.

Gravity-driven falling and stacking

Pressure that pushes, pulls, and crushes cubes

Temperature spreads to melt and freeze cubes

Acids and bases that dissolve their surroundings

Biology that rots and metals that rust over time

Experiment with hundreds of interacting materials

Create beautiful environments

Simulate natural processes—or unleash complete destruction

Explosives and volatile compounds

Reactive metals and oxidizing elements

Fuels, gases, liquids, and structural solids

Emergent gameplay driven by systems reacting to your actions

Apply Pressure, Temperature or combine chemicals to unlock each and every cube
