Nonogram
A logic puzzle in which the player fills in cells of a grid based on numeric run-length clues to reveal a hidden image.
Origin and context
Also called Picross or Paint by Numbers. Each row and column has a sequence of numbers describing the lengths of consecutive filled cells. Solving requires constraint propagation: a row of "5" in a 5-cell row forces every cell filled; "2 1" in 5 cells has only two valid arrangements.
