Falling Sand
Choose a material, then draw with a pointer or a finger.
How to play Falling Sand
- Paint with sand, water, oil, or walls in Free sandbox. Adjust the brush and use the eraser to open gaps.
- Try one of the three challenges and guide existing material into the outlined target. Pause to build before starting the simulation.
- Reset restores the selected scene so you can try a different setup.
Sand sinks through liquid, and oil floats on water. Make a sloped wall to guide falling material or open a small gate to release it slowly.
Can I play on a phone?
Yes. Draw directly on the sandbox with one finger. Use a smaller brush for narrow gaps.
