Paint By Numbers

Paint By Numbers is a classic Macintosh implementation of the Japanese logic puzzle variously known as Picross, Nonograms, or Griddlers. The player reveals a hidden pixel picture by deducing which cells in a grid should be filled, using only the run-length clues printed along each row and column.

Gameplay

Each puzzle is a rectangular grid with numeric clues describing the lengths of consecutive filled runs in every row and column. By cross-referencing the clues, the solver marks cells as filled or empty until a small monochrome image emerges. Puzzles are solved purely by logic, with no guessing required for a well-formed board.

Why it endures

The Picross/Nonogram format pairs short solving sessions with a satisfying reveal of pictorial art at the end, which is why it has survived from newspaper puzzle pages onto computers, handhelds, and modern phones. The Mac version brings that loop to System 7-era hardware.

Distribution

The title is preserved on Macintosh Garden as a small downloadable archive intended for classic Mac OS or emulators such as SheepShaver and Basilisk II.
