Falling Sand
Play a free falling sand game with four materials. Experiment in a free sandbox or solve three particle challenges with walls and gates.
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.
How can I see oil float on water in the sandbox?
Draw a U-shaped container with the Wall tool. Add water to the container, then add oil above it and let the simulation run. Water settles under the oil. The Oil layer challenge starts with both liquids ready to release.
Can I play on a phone?
Yes. Draw directly on the sandbox with one finger. Pause to build walls, and use a smaller brush for narrow gaps.
