Draw with sand, water, fire, wood, acid and smoke — watch substances interact with physics and chemistry rules. Fire ignites wood, acid dissolves materials, water pools at the bottom.
Each pixel is a cell that follows rules: sand falls with gravity and piles at the angle of repose, water flows and fills cavities, fire uses cellular combustion rules.
Select a substance and draw with the mouse. Combine materials to see reactions: fire + wood = smoke, acid dissolves most materials, water extinguishes fire.
This "falling sand" genre traces back to 1986's Tetris-inspired experiments and the 2005 classic "Powder Game". Modern games like Noita (2020) push pixel physics to extraordinary complexity.
