Free printable mosaic
Mosaic, also called Fill-a-Pix, is a shading puzzle that builds a picture from neighbour counts. Each printed number tells you how many of the squares touching it, including the numbered cell itself, must be shaded: a 0 is a fully empty block, a 9 is a solid 3x3, and blank cells still belong to the picture. Solvers who like Nonograms but want a single number per cell rather than row-and-column strips often enjoy Mosaic.
Solution page included
Peek at the solution
This page offers a 6x9 inch high-resolution PNG of a 15x15 Mosaic, plus a matching solution PNG of the finished shading. There is no word list and no colour key, just the numbered grid. Download both files with no signup and print them at home.
How to play
- Read each number as a count of shaded squares touching it, including itself.
- Shade every neighbour of a 9, and leave every neighbour of a 0 empty.
- Use overlapping clues to decide the blank cells that have no number of their own.
- Keep shading until the counts match, then compare the picture with the solution PNG.
Print at 100% scale on letter or A4 paper so the 15x15 clues stay sharp enough to shade against.
Frequently asked questions
How do I see the finished Mosaic picture?
The solution PNG on this page shows the completed 15x15 shading. Download it with the puzzle if you want to check a region, or wait until you think the picture has appeared. It is an answer key, not a separate colouring sheet.
Is the Mosaic download actually free?
Yes. Both the puzzle PNG and the solution PNG are free, with no signup and no email gate. Print them for personal use as many times as you need. This page is not a PDF booklet and has no difficulty picker.
Who should try this 15x15 Mosaic?
It is a good fit for people who like picture-logic grids and are comfortable scanning a denser 15x15 board. The 0s and 9s give you immediate blocks of empty or solid cells, so patient beginners can start there. Adults, teens, and experienced Nonogram solvers usually enjoy watching the hidden picture emerge.
How do I print this Mosaic so the 15x15 numbers stay readable?
Print the PNG at 100% scale on letter or A4 paper. The 15x15 grid is the densest on this page, so fit-to-page shrinking makes the clues hard to tell apart. Use black ink, and consider a slightly heavier sheet if you will erase while you shade.
