Definition: Nonograms are logic puzzles in which squares in a grid are colored or left blank according to numbers given at the side of the grid. Once completed, the puzzle reveals a hidden picture. Nonograms may be black and white or colored, in which case the number clues are also colored to show the color of the squares. Nonograms can be of any size or shape.
