Enter row and column clues to solve small nonogram, picross, griddler, and paint-by-number puzzles directly in your browser.
Start with the sample diamond puzzle, then replace the clues with your own grid.
How to useStart with the puzzle in front of you, then check the result against what you can actually place, read, or mark.

Start here when a nonogram gives you row clues and column clues and you want the grid filled logically.
The tool is best for small logic grids where manual deduction is possible but tedious. It is also useful for checking whether a clue set has one solution or multiple possible grids.
Enter one row clue per line and one column clue per line. Separate groups with spaces or commas, such as 1 3 or 2,1. Use 0 for a row or column with no filled cells.
The order matters. Row clues should go from top to bottom, and column clues should go from left to right. A swapped clue can make the puzzle impossible or produce a different image.
The solver creates every legal pattern for each row and column, then searches for a grid where all of those patterns agree. This mirrors the logic behind hand-solving nonograms.
If the solver reports no solution, check clue length first. If it reports multiple solutions, the clue set may be incomplete or intentionally ambiguous.
Nonogram, Picross, Griddlers, and paint-by-number puzzles use the same clue logic. Use the Picross page if that is the name your puzzle app or book uses.
Use either page for the same clue format. Choose the page name that matches the puzzle you are working on.
A result only helps when the input matches the real puzzle. Check these points before using a move, word path, cipher hint, or filled grid.

The tools do not play games for you or keep an account profile. They work from the input on the page. If a result looks wrong, fix the board, clue list, image grid, or cipher text and run it again.
Solver logic is checked with sample puzzles, edge cases, and browser flows before updates go live. Image and OCR results stay editable because screenshots, lighting, and cropped boards can change detection quality.
Enter one row or column clue per line. Use numbers separated by spaces or commas, and use 0 for an empty line.
Yes. Nonogram, Picross, Griddlers, and paint-by-number logic puzzles use the same clue format.
It means the clue set does not force one unique grid. Check that every row and column clue was copied correctly.
It works best on small grids, roughly up to 15 by 15.
