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.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 at the beginning and sometimes later but not often
