The history of nonograms
From lit windows in 1980s Tokyo to Game Boy cartridges — and back to paper.
Every nonogram you solve today — on paper, on your phone, on a train — descends from apartment windows in 1980s Tokyo. The history of nonograms is short, strange and lovely, and it begins with a designer looking at a skyscraper after dark.
1987: pictures made of windows
Non Ishida, a Japanese graphics editor, saw what most of us miss: an office tower at night is a grid, and its lit and unlit windows are pixels. She created “window art” — images formed by switching building lights on and off — and in 1987 won a design competition in Tokyo with the idea. Around the same time, a professional puzzler named Tetsuya Nishio arrived at the same concept independently: pictures encoded in numbers, revealed by logic. Great ideas often have two parents.
1990: the puzzle gets a name
Ishida’s grid puzzles began appearing in Japanese magazines, and in 1990 they crossed the world: British puzzle editor James Dalgety introduced them to readers of a UK newspaper and coined the name that stuck — nonogram, from Non Ishida + diagram. The same puzzle would soon collect aliases everywhere it landed: Hanjie, Griddlers, Pic-a-Pix, Japanese crosswords.
1995: Nintendo presses start
The puzzle’s global breakthrough came in 1995, when Nintendo released Mario’s Picross for the Game Boy. “Picross” — picture crossword — became the name a whole generation learned first. The series never really stopped: new Picross titles have accompanied every Nintendo console since, quietly making the nonogram one of the most-played logic puzzles on Earth.
2000s–today: from apps back to paper
Smartphones turned nonograms into a daily ritual for millions, with endless free grids one thumb-tap away. And yet something curious happened on the way to total digitisation: solvers came back to paper. A printed grid asks for your full attention — no hints, no undo, no ads — and rewards it with the small, real satisfaction of a picture drawn by your own logic. That return to slow solving is exactly where The Logic Atelier lives: hand-curated grids, printed beautifully, solved with a pencil.
A 40-year-old idea that still feels new
From lit windows in Tokyo to a Game Boy cartridge to the book on your desk, the nonogram has survived every format change for one reason: the moment the picture reveals itself never gets old.
