Overview
About this game
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
