Free Nonogram Maker (Printable PDF)

A nonogram, also called a picture cross or griddler, is a logic puzzle where the numbers beside each row and column tell you which squares to fill to reveal a hidden picture. This free nonogram maker builds a fresh, single-solution grid every time, so careful reasoning always works and you never have to guess. Read the run-length clues, then drag across the grid to fill the squares you are sure about and leave the rest blank. The picture slowly emerges as the rows and columns line up and confirm one another. When the grid matches every clue, you have solved it. Download a clean, printable PDF with the finished picture on its own page, ready for quiet focus time, a long trip, or a classroom logic challenge. More themed grids are on the way.

How to make it

  1. Read the number clues beside each row and each column.
  2. Drag across the grid to fill the squares the clues require.
  3. Leave squares blank where a run cannot reach; the picture appears.
  4. Solve it on screen, or download the printable PDF with the solution.
