How to play Sand sandbox

Pick a material: sand, water, stone, wood, plant or fire. Tap or drag on the canvas to drop it. Sand piles into hills. Water flows downward and pools. Stone and wood sit where you put them. Plants grow near water, and fire spreads through fuel until water puts it out. Pause and play to control the simulation. Tap erase to remove material. There are no goals, just play with the physics.

Tips

Build a stone bowl first, then pour water into it
Pile sand on slopes to see the angle of repose
Set wood or plants on fire, then use water to stop the spread
Save a screenshot, the canvas wipes when you reload

About Sand sandbox

Falling sand games started on Japanese forums in 2005 with the original Sand Game by Hi Taro. The simple particle physics, each pixel checks its neighbour and falls or settles, exploded into thousands of remixes and inspired bigger games like Powder Toy and Noita. Our small version stays close to the original feel. A handful of materials, smooth physics, a quiet pace. Open it in a tab when you need to space out for a few minutes.
