Picross vs Nonogram: What Is the Difference?
Same Puzzle, Different Names
If you’ve searched for grid-based logic puzzles, you’ve probably seen both “picross” and “nonogram” and wondered: are these the same thing? The short answer is yes — they are the exact same puzzle with different names. But the history behind each name tells an interesting story.
Where “Nonogram” Comes From
The puzzle was invented in 1987 by Non Ishida, a Japanese graphic designer. She was inspired by the pattern of lit and dark windows in a skyscraper at night — a natural grid with some cells “on” and others “off.”
The name “nonogram” is derived directly from her name: Non + gram (from “diagram”). When the puzzle spread internationally through puzzle magazines in the late 1980s and early 1990s, “nonogram” became the standard academic and international name.
Around the same time, Japanese puzzle author Tetsuya Nishio independently developed a nearly identical concept. Both inventors contributed to the puzzle form we know today.
Where “Picross” Comes From
“Picross” is a brand name created by Nintendo. It’s a portmanteau of Picture + Crossword, describing how the puzzle uses crossword-style clues to reveal a picture.
Nintendo released Mario’s Picross for the Game Boy in 1995, which became the single biggest driver of the puzzle’s global popularity. The Picross brand continued across multiple Nintendo platforms:
- Picross DS (2007) — introduced online puzzle sharing
- Picross e series (2011–2015) — Nintendo 3DS digital titles
- Picross S series (2017–present) — Nintendo Switch, still actively releasing
Because of Nintendo’s massive reach, many English-speaking players know the puzzle exclusively as “picross” and have never encountered the word “nonogram.”
Other Names for the Same Puzzle
The puzzle has accumulated names in different regions:
| Name | Origin | Where Used |
|---|---|---|
| Nonogram | Non Ishida (Japan, 1987) | International, academic |
| Picross | Nintendo (Japan, 1995) | Gaming community, English-speaking world |
| Griddlers | The Sunday Telegraph (UK, 1990s) | United Kingdom |
| Hanjie | ”Chinese puzzle” (misnomer) | Some UK publications |
| Paint by Numbers | Descriptive English name | General use |
| Oekaki Logic | Japanese (お絵かきロジック) | Japan |
| Logic Art | Descriptive name | Korea, general use |
All of these refer to puzzles with the same rules: numbered clues on rows and columns, fill cells to reveal an image.
Are There Any Actual Differences?
While the base puzzle is identical, the “Picross” brand has introduced some variants that are specific to Nintendo’s games:
Mega Picross
Some clues span two adjacent rows or columns. A clue of “5” across rows 1 and 2 means that 5 cells total are filled across both rows in the same columns. This is significantly harder than standard nonograms and is unique to Nintendo’s Picross S series.
Clip Picross
A large image is divided into smaller nonogram puzzles. Solving each small puzzle reveals a piece of the larger picture. The edges of adjacent puzzles provide hints for each other.
Color Picross
Instead of just filled/empty cells, puzzles use multiple colors. Each color has its own set of clues. Blocks of different colors don’t need a gap between them (since the color change is the separator). Color nonograms aren’t exclusive to Nintendo — they appear in many apps — but Picross S popularized the format.
Standard nonograms and standard picross puzzles, however, are completely interchangeable. A 10×10 nonogram from a puzzle magazine follows the same rules as a 10×10 picross puzzle from a Nintendo game.
Which Term Should You Use?
It depends on context:
- Searching online: Use “nonogram” for puzzle apps, websites, and solvers. Use “picross” when looking for Nintendo games specifically.
- Talking to gamers: “Picross” is more widely recognized in gaming circles.
- Academic or technical contexts: “Nonogram” is the standard term in computer science and puzzle theory.
- SEO reality: Both terms have strong search volume, which is why most nonogram websites (including noguelike.com) mention both.
The Community Doesn’t Care
In practice, the nonogram/picross community uses both terms interchangeably. Nobody will correct you for saying one instead of the other. What matters is the puzzle itself — numbered clues, logical deduction, and the satisfying reveal of a hidden picture.
Whether you call it picross, nonogram, griddlers, or paint by numbers, you’re talking about the same brilliant puzzle that’s been entertaining millions since 1987. The name is just the label — the logic is universal.
