Modern Nonograms emerged in Japan in the late 1980s through two independent lines of development associated with Non Ishida and professional puzzle creator Tetsuya Nishio. The puzzle then spread internationally through print publishing, acquired several names, and became especially visible in digital games during the 1990s and beyond.
The exact naming history matters because “Nonogram,” “Griddlers,” “Hanjie,” “Picross,” and other labels do not all come from the same publisher or moment.
1987: grid pictures and an independent puzzle idea
Puzzle historian James Dalgety's account traces one origin to Non Ishida, a Japanese graphics editor who in 1987 won a Tokyo competition with grid pictures created by switching skyscraper lights on and off.
The on/off windows naturally form a binary grid: some cells are lit and others are not. That visual idea led toward reconstructing pictures cell by cell.
At around the same time, Tetsuya Nishio, a professional Japanese puzzle creator, independently developed a puzzle using the same basic picture-grid logic.
The history is therefore better described as independent invention than as one person simply copying the other.
1988: Window Art Puzzles
In 1988, Ishida published picture-grid puzzles in Japan under the name Window Art Puzzles.
The name reflects the skyscraper-light origin of the idea. At this stage, the English word Nonogram had not yet been coined.
1990: the name “Nonogram”
James Dalgety, a British puzzle collector and historian, encountered Ishida's work and helped bring it to a wider audience outside Japan.
Dalgety's own history records that in 1990 he coined the name Nonogram, combining “Non” from Non Ishida with “gram” from diagram.
He also arranged for the puzzles to appear weekly in The Sunday Telegraph in Britain, giving the format sustained newspaper exposure outside Japan.
1993: books and broader print distribution
By 1993, dedicated Nonogram books were appearing in Japan and Britain. Dalgety's history notes both a Japanese book by Ishida and The Sunday Telegraph Book of Nonograms in the UK.
The puzzle also spread through other countries and publishers, often under locally preferred or publisher-specific names.
That proliferation of names is one reason two people can know exactly the same rules while calling the puzzle something different.
Why are Nonograms called so many different things?
As the puzzle spread, publishers frequently introduced their own titles.
Names encountered in English-language puzzle history include:
- Nonogram;
- Griddlers;
- Hanjie;
- Paint by Numbers;
- Pic-a-Pix;
- Picture Logic;
- Picross in Nintendo's game series.
These names can overlap in everyday usage, but their histories and trademark status are not identical.
VeyraPlay uses Nonogram as the canonical generic name for this editorial vertical and handles naming distinctions in a dedicated comparison Guide.
1998: Griddlers
Dalgety's puzzle-history archive records that The Sunday Telegraph later ran a reader competition for a new name and selected Griddlers in 1998.
That helps explain why Griddler remains familiar to many British and European puzzle readers even though Nonogram is widely used online today.
The move into digital games
Picture-logic puzzles were a natural fit for digital devices because cells can be filled, cleared, marked, checked, and navigated easily on a screen.
By the mid-1990s, console and handheld versions had become part of the puzzle's history. Nintendo's Picross releases helped make the format recognizable to video-game audiences, even among players who did not use the word Nonogram.
The rules remained based on the same core idea: reconstruct a hidden grid image from ordered row and column clues.
What changed as Nonograms became digital?
The underlying puzzle did not need to change, but software added product features such as:
- input assistance;
- timers;
- mistake checking;
- hints;
- zooming and navigation for large grids;
- puzzle libraries and daily content;
- automated puzzle validation.
Those are interface and distribution changes, not new evidence rules. A standard Nonogram deduction is still determined by its clues and known cell states.
From newspaper puzzle to puzzle family
The history of Nonograms is unusual because the format spread through many naming ecosystems rather than one universally controlled title.
Today the same basic monochrome puzzle can appear in:
- puzzle books;
- newspapers and magazines;
- websites;
- mobile apps;
- console games;
- printable collections.
The result is a global puzzle family with unusually fragmented terminology but a very stable core rule set.
A short Nonogram timeline
1987 Non Ishida's grid-light artwork; Tetsuya Nishio independently develops similar puzzle logic
1988 Ishida publishes Window Art Puzzles in Japan
1990 James Dalgety coins “Nonogram”; weekly publication begins in The Sunday Telegraph
1993 Dedicated Nonogram books appear in Japan and Britain
mid-1990s Digital/handheld implementations and Picross-branded games broaden the audience
1998 “Griddlers” is selected in a Sunday Telegraph naming competition
later Web, mobile, console, daily, and printable formats expand the puzzle worldwideWhy the history matters for modern search terms
A player searching for “Picross strategy,” “Griddler clues,” or “Hanjie rules” may be looking for the same standard picture-logic mechanics covered by a Nonogram guide.
Editorially, that means aliases are useful for recognition and internal linking, but they should not force us to create duplicate pages for every historical name.
The naming story belongs in the corpus; duplicate intent does not.

FAQ
Who invented Nonograms?
The modern puzzle is generally associated with independent development in Japan by Non Ishida and Tetsuya Nishio in the late 1980s.
Where does the word Nonogram come from?
James Dalgety's history says he coined it in 1990 from “Non” Ishida plus “gram” from diagram.
Is Picross the original name?
No. The puzzle predates Nintendo's Picross game branding. G-014 covers the naming distinction in detail.
Were Nonograms originally computer games?
No. Their early history is tied to visual grid artwork and print puzzle publishing; digital versions came later.
