Moss Chart

Moss Chart is a picture-logic puzzle. The numbers beside each row and above each column give the runs of filled squares in order — everything you need is in them. Fill what the numbers prove is filled, cross off what they prove is empty, and let the two sides of the grid tell you the rest. Switch between paint and cross with one button. Every board here has exactly one solution, and every one of them can be reached by reasoning alone — each level was checked by a line solver before it shipped. There is never a point where you have to guess. Ten levels, from a five-by-five warm-up to a ten-by-ten that will take a while. Half the squares are filled, give or take, so the clues stay worth reading. Offline, no accounts, no forced ads, nothing to buy. Features: - Clues on both axes — paint what they prove - Exactly one solution per board, reachable by logic alone - No guessing: every level verified by a line solver - Paint and cross modes, reset whenever - Ten levels - Works fully offline
