Sand Trace - Pixel Physics Sim

Drop sand, pour water, ignite fire, and watch real physics come to life. Sand Trace is a pixel-art physics simulator where you paint with 16 different materials and watch them interact in surprising ways.

WHAT YOU CAN CREATE
- Drop sand, stone, and glass to build structures
- Pour water, oil, and acid to watch fluids flow
- Ignite wood, oil, and plants to set off massive fires
- Spawn lava to melt ice and turn water to stone
- Launch missiles and detonate explosives for chain reactions
- Electrify water with lightning bolts
- Grow forests by placing plants near water
- Heat sand into glass for permanent structures

16 MATERIALS, 40+ INTERACTIONS
Every material has unique physics. Sand falls and piles up. Water flows and extinguishes fire. Lava melts ice and hardens into stone. Acid corrodes nearly everything. Lightning electrifies water in a spreading chain. Oil floats on water and burns with thick smoke. Plants grow toward water and catch fire easily. Discover every interaction through experimentation.
