Nonograms, also known as Picross or Griddlers, have a fascinating history that began in Japanese puzzle magazines. In 1988, Non Ishida introduced three picture grid puzzles in Japan called "Window Art Puzzles." Two years later, in 1990, James Dalgety in the UK named them "Nonograms" after Non Ishida, leading to their weekly publication in The Sunday Telegraph.
In Japanese nonograms, the numbers function as a form of discrete tomography, indicating the number of unbroken lines of filled-in squares in any given row or column. For example, a clue like "4 8 3" means there are groups of four, eight, and three filled squares in that order, separated by at least one blank square. Solving these puzzles involves determining which squares to fill and which to leave empty.
While nonograms are typically rendered in black and white, representing a binary image, they can also incorporate color. When colored, the number clues are colored accordingly to indicate the hue of the squares. For instance, a black four followed by a red two could mean four black boxes followed by empty spaces and then two red boxes, or simply four black boxes immediately followed by two red ones.
