Printable nonograms
Nonogram grids in PDF with the row and column clues, from a small evening grid to large weekend ones. Every grid has a single solution, and you reach it by logic, never by guessing.
How it works
Pick a size and a difficulty
10 × 10 to learn, 15 × 15 for fun, 20 × 20 for long evenings. The higher the difficulty, the fewer cells the clues give away at the start.
Generate your set
Choose the number of grids and the paper: the preview shows the first grid with its clues, and the “Another set” button offers new ones.
Print and fill in
One grid per page, the solutions four to a page at the end. The numbers on the left and above say how many cells to fill in a row.
Printing tips
Choose “Actual size” or “100%” in the print dialog, not “Fit to page”: the cells stay large enough, at least 6 mm, for a sharp pencil. Black and white is enough, there is no coloured background. A heavier line comes back every five cells to help you find your place and count. For a class or a workshop, print the solutions on a separate sheet and keep it.
Frequently asked questions
How do you solve a nonogram?
Each number gives the length of a run of filled cells in its row or column, in order, with at least one empty cell between runs. Start with the lines whose clues fill almost the whole width, then cross rows and columns. Mark the cells you know are empty with a cross.
Do I need to guess to finish a grid?
No. Every grid has a single solution and you reach it by reasoning line by line: our solver checks it before layout. If you are stuck, a line escaped your attention, you never need to gamble.
What is the difference between easy, medium and hard?
Difficulty measures the share of lines the clues let you fill straight away. On easy, many lines fill in at once; on hard, you have to chain deductions from the very start.
Can I use them in class or in a workshop?
Yes, freely, including printing them in quantity. Only reselling the files is not allowed. Your settings are kept on your device only, nothing is sent to a server.
