What is a nonogram?
A nonogram is a grid with number clues beside each row and column. The numbers say how many filled cells run together in that line. Filling the right cells reveals a picture, and the picture name is only shown on the answer page.
Can I make a nonogram from my own picture?
Yes. Add your own images and the maker converts them to a grid in your browser — nothing is uploaded. You can also draw pixel by pixel in the editor, or use the built-in picture library.
Are the puzzles solvable without guessing?
Yes. Each puzzle is run through a line solver before you see it. If a picture cannot be solved by deduction alone, the fewest possible cells are revealed as starting hints, and the maker tells you how many.
Can nonograms be printed in colour?
Yes. Two-colour nonograms are supported, with print-safe palettes. The default uses black plus hatched grey, so the puzzle still works on black-and-white interiors.
