DRAW A LINE TO POUR THE SAND
ONE COLOR MUST TOUCH BOTH WALLS
▶ PLAYThe one rule the demo can't show you: one color must touch both walls. SAND PAINT is already running when the page opens — the built-in AI plays it for you, so you can see what it is before you touch anything. Tap once to take over mid-run: nothing to read, nothing to wait for. Every run is measured against the live world record. Swipe up whenever you want the next game.
