The history of nonograms

Nonograms are picture logic puzzles: you fill cells on a grid according to number clues until a hidden image appears. They feel timeless, but the modern puzzle is surprisingly young — it was born in the late 1980s and grew up across Japan, the UK, and the video-game industry. Here is how it happened, in roughly the order the story is usually told. If you are brand new to the rules, the daily puzzle is the fastest way to get a feel for them.

1980s Japan: two independent inventors

The puzzle is most often credited to Non Ishida, a Japanese graphics editor, and to Tetsuya Nishio, who are widely reported to have arrived at the idea independently around 1987–1988. The frequently told origin story is that Ishida won a competition by creating images out of the lit and unlit windows of tall buildings — in effect treating a skyscraper's grid of windows as pixels in a picture. That idea of encoding an image as filled and empty squares is exactly what a nonogram is.

Around the same time, Nishio developed a comparable grid puzzle, and early examples began appearing in Japanese puzzle magazines. Because two people are independently credited, it is fairer to say nonograms emerged in Japan in this period than to name a single inventor. The puzzles caught on quickly with magazine audiences, which set the stage for them to travel abroad.

Early 1990s: the UK and the name “nonograms”

The puzzles reached the United Kingdom in the early 1990s. The British puzzle expert James Dalgety is generally credited with coining the name “nonograms”— a nod to Non Ishida — and the puzzles were published in The Sunday Telegraph, which helped popularize them with a large newspaper readership.

Newspaper publication mattered: it turned a niche import into a regular feature that ordinary solvers looked forward to each week. That weekly cadence is, in a sense, a distant ancestor of today's daily online puzzle.

The naming explosion: griddlers, hanjie, pic-a-pix

As the puzzle spread, it picked up a confusing pile of names. A 1998 Sunday Telegraph reader competition is commonly cited as the origin of the name “griddlers”. Elsewhere the same puzzle was published as hanjie, pic-a-pix, and picture cross, among others. Different magazines, publishers, and countries each tended to favor their own label.

This is why a single puzzle type answers to so many names today, and why search results for “nonogram” and “griddler” often lead to the same thing. If the terminology ever trips you up, the glossary untangles the vocabulary, and our comparison of nonograms vs other puzzles shows how they relate to sudoku, crosswords, and the rest.

Nintendo and “Picross”

The name most people recognize today — Picross— comes from Nintendo. “Picross” is a contraction of “picture crossword,” and Nintendo trademarked the term and built a long-running series around it. The breakthrough title was Mario's Picross, released for the Game Boy in 1995, which introduced the puzzle to a huge gaming audience.

Nintendo has kept the brand alive for decades since, with many entries including the Picross S series on the Nintendo Switch and the collectible-flavored Pokémon Picross. Thanks to that steady stream of games, “picross” is now one of the most searched names for the puzzle — often more familiar than the original word “nonogram” itself.

The web and the daily-puzzle era

As the internet matured, nonograms moved online. Web solvers let anyone play in a browser without pencil, eraser, or a magazine subscription, and a wave of mobile apps — titles like Nonogram.com and many others — put the puzzle in everyone's pocket. Digital grids also made larger and color puzzles practical, since the software handles the bookkeeping for you.

The most recent chapter is the daily puzzle format that this site follows: one fresh, hand-verified logic puzzle every day, the same for everyone, with no guessing required to reach the single solution. It echoes the old newspaper rhythm but with instant feedback, undo, and a streak to keep. More than thirty years after a row of lit office windows suggested a picture made of squares, the nonogram has become a small daily ritual for solvers around the world.

A note on accuracy

Puzzle history is passed down through magazines, newspapers, and enthusiast accounts rather than formal records, so some details — exact years, who did what first — are reported with small variations. Where authorship is shared, we have said so (“independently credited”) rather than overstating certainty. The broad arc, though, is well established: Japan in the late 1980s, the UK naming it shortly after, Nintendo popularizing “picross,” and the web turning it into a daily habit.
