Free printable nonograms with answers

A nonogram, also called a picross or a griddler, is a picture hidden behind numbers. The clues beside each row and column are the lengths of the filled runs, and shading the cells the clues demand reveals a picture. Every puzzle here is proved to solve by logic alone, with no guessing.

By size

Size is what makes a nonogram harder: a bigger grid has more lines to hold in your head at once. Start on a 5 by 5 and work up to a 15 by 15.

By name and audience

The same puzzle goes by several names, and suits several solvers. Picross, griddler, or a gentle grid for a child or a beginner, they all solve the same way.

One picture, proved by logic

The thing that makes a nonogram book worth printing is the guarantee most sellers cannot make: that the clues have exactly one picture, reachable without guessing. Every puzzle is generated by painting a picture, reading its clues, and running a line solver that proves the deductions alone finish it. The solved picture prints as the answer key, so it can never disagree with the clues.

Make one now

Pick a size from a gentle 5 by 5 up to a 15 by 15, then print the puzzle and its solved picture. No sign-up, no watermark.
