Nonograms (also known as Hanjie, Picross, Griddlers) are logic puzzles where players fill in a grid, following numerical clues provided for each row and column. These clues indicate the lengths of consecutive filled cells (blocks) that must be separated by at least one blank cell. Originating in Japan in the late 1980s, they were independently created by Non Ishida and Tetsuya Nishio.
Nonograms
In Nonograms, the cells in the grid have to be colored according to the clues at the top and left of the grid.
The clues provided next to each row and column indicate the lengths of consecutive filled cells (blocks) in that row or column. These blocks must appear in the order of the clues.
There must be at least one blank cell separating consecutive blocks.
The puzzle is complete when all clues are satisfied.
If you are sure a cell will be blank, it can be marked with an x. This can help in completing the puzzle.
The Nonogram puzzles on our website come in 4 sizes: 10x10, 15x15, 20x20, and 25x25.
For each of these sizes, there is a daily puzzle you can solve.
Click or tap on an empty cell to fill it. Click or tap again to mark the cell with an x. Click or tap again to empty the cell again.
It is also possible to click and drag across multiple cells.
There are some shortcuts that can be used on the computer: Undo (Z), Redo (Y), Reset puzzle (R), Save (S).
Nonogram puzzles have their origins in the late 1980s in Japan, where they were created independently by two designers: Non Ishida and Tetsuya Nishio.
Non Ishida, a Japanese graphics designer, is often credited with inventing the concept in 1987 when she won a contest to design a new type of logic puzzle. Her idea was inspired by creating grid-based designs using lights on skyscrapers, which led to the development of puzzles where solvers would shade in cells on a grid to form a hidden image.
Around the same time, Tetsuya Nishio came up with a similar concept. His puzzles were published in a different magazine, and they quickly gained popularity due to their unique combination of logic and artistry.
In 1990, James Dalgety from the UK invented the name Nonograms, deriving it from one of its inventors "Non”.
Nonogram puzzles are known with many different names, for example: Hanjie, Paint by Numbers, Crosspix, Griddlers, Pic-a-Pix, Picross, Edel, Japanese Crosswords, Logimage.
Another logic puzzle game on our site in which the grid has to be filled with black and white cells is Nurikabe.
Nonograms can be played in all modern browsers, on all device types (desktop, tablet, mobile), and on all operating systems (Windows, macOS, Linux, Android, iOS, ...).
