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.

How to solve a nonogram

The numbers around the grid describe a hidden picture. Shade the right squares and it appears.

The method

  1. 1Read the clues as runs. Each number is a block of shaded squares in that row or column, and the numbers are given in order.
  2. 2Start where the numbers are tight. A long run, or several runs that nearly fill a line, leaves only one way to place them. Shade what every arrangement agrees on.
  3. 3Mark the empty squares too. Cross out squares you can prove stay blank. Those crosses often force the next shaded square.
  4. 4Cross-check rows against columns. A square shaded for a row must satisfy its column as well. Work the two together until the picture is complete.
The one rule
Each line is shaded to match its clue numbers in order, with at least one blank between runs.
What the answer page shows
Every solved picture is printed at the back, so you can check your grid.
How the grades differ
Small grids reveal a simple shape fast. Larger grids hide more detail and take more cross-checking.
Good for
Anyone who likes a picture as the reward, from quick warm-ups to a long solve.
