The History of Nonograms

Nonograms are young, as puzzles go. They started in Japan in the late 1980s, reached Western newspapers in the early 1990s, and became a video game staple not long after. Here's how it happened, as far as the records agree.

Born in late-1980s Japan

Japanese puzzle publishing was booming in the mid-1980s, and creators were trying grid formats that went beyond placing numbers. The Nonogram was one result: clues describe runs of filled squares, and solving reveals a picture.

Two separate lines of work are usually credited, and they overlapped in time.

Window Art

The Japanese designer Non Ishida is widely credited with publishing a picture-logic puzzle in the late 1980s, usually called Window Art. The idea was simple and visual: numbers along the edges tell you which squares to fill, until a picture appears.

Oekaki Logic, in parallel

Around the same time, Tetsuya Nishio is credited with a very similar puzzle, published under a name usually translated as Oekaki Logic, or "drawing logic".

Because the two appeared close together in the same publishing scene, there's no clean answer to who invented the Nonogram. Both names are part of the story.

Where the English name came from

"Nonogram" is usually explained as a blend: NON from Non Ishida, plus -gram from diagram. The British puzzle collector James Dalgety is commonly credited with coining it.

That's also why the name looks mathematical but isn't. It's a nod to a person, not a description of arithmetic.

Reaching Western newspapers

In the early 1990s the puzzles started showing up in British newspapers, most often cited as The Sunday Telegraph, then spread to other papers and puzzle books.

This is when the English-speaking world met the puzzle, and when the competing names started to circulate. That's why the same puzzle is known today as Nonogram, Hanjie, Griddlers, and Japanese crossword.

Picross and the video game era

Video games gave the puzzle its biggest audience. Nintendo's Mario's Picross, released in the mid-1990s for the Game Boy, popularised the name Picross (a Nintendo trademark) and put the format in front of people who'd never opened a puzzle magazine.

More Picross titles and a long list of independent puzzle games have kept it alive since.

The digital age

The internet changed three things at once:

Supply. A computer can generate and verify puzzles, so a site can offer nearly endless boards instead of a fixed print run.
Feedback. Digital puzzles add hints, undo, error checking, and saved progress, none of which paper can do.
Habit. A shared daily puzzle, the same for everyone each day, turns solving into a routine.

A global puzzle today

Nonograms are now solved in dozens of languages and on every device. The rules haven't changed since the 1980s. Only the delivery has.

Quick answers

Who invented the Nonogram?

Two people are commonly credited, working independently in late-1980s Japan: Non Ishida (Window Art) and Tetsuya Nishio (Oekaki Logic). The exact priority is disputed.

When were they invented?

Late 1980s, with wide English-language exposure arriving in the early 1990s.

Where does the name come from?

Most commonly explained as "NON" from Non Ishida plus "-gram" from diagram.

Are Nonograms older than Sudoku's boom?

Both have Japanese roots in the 1980s. Sudoku's worldwide moment came later, in the mid-2000s, while Nonograms reached Western newspapers earlier, in the early 1990s.
