Falling Cubes

Inspired by falling sands simulations, Falling Cubes is a 3D sandbox where physics, chemistry, and reactions interact in real time. Drop cubes, trigger reactions, and watch as cubes fall, flow, burn, explode, and transform in a fully dynamic world.

Experiment freely and discover over 200+ unique cube types.

• Every cube is simulated

• Gravity-driven falling and stacking

• Liquids that spread, react, and evaporate

• Gases that rise, ignite, and dissipate

• Fire, temperature, and oxidation systems

• Test interactions between hundreds of materials

• Create beautiful environments

• Simulate natural processes or pure destruction

• Explosives and volatile compounds

• Reactive metals and oxidizing elements

• Fuels, gases, liquids, and structural solids

• Hidden interactions waiting to be uncovered

• No predefined solutions

• No single “correct” outcome

• Emergent gameplay driven by your actions

• Graphics

  • Ray traced voxels

• Audio

  • There’s music
