Falling sand game online
A sand simulator where grains fall, water flows and fire spreads. Pick a material, set the brush size and draw with the mouse or your finger.
How to play the falling sand game
Pick a material from the top bar (sand, water, stone or fire) and drag over the screen to pour it. The eraser removes anything it touches.
Every grain and drop follows simple physics: sand forms piles, water flows and spreads, stone stays put and works as a wall. Mix the materials and see what happens.
Fire rises, goes out when it touches water and turns nearby sand into glass. Use the brush sizes for fine details or for big mountains.
Frequently asked questions
What is a falling sand game?
It is a simulator where every pixel is a particle with its own rules, such as sand that falls or water that flows. A few simple rules create complex behavior, like hourglasses and rivers.
How do I make a waterfall?
Draw a stone wall with the stone tool, leave a gap, and pour water from the top. The water falls, hits the stone and runs down the path you left.
Can I play on a phone?
Yes. Drag your finger over the screen to pour materials. The buttons are large and the simulation runs in your browser.
