Mosaic puzzles online
A mosaic puzzle gives you a grid of number clues. Each number counts the filled cells in the 3×3 block around it, including its own cell. Combine neighboring clues and the fills fall into place one by one.

How to play Mosaic Puzzle
- Some cells show a number from 0 to 9.
- A number tells how many cells in its 3×3 block are filled, counting the cell itself and its eight neighbors.
- Click to fill a cell, and mark cells you know are empty.
- The puzzle is solved when every number matches its filled cells.
Mosaic Puzzle tips
Start with 0 and 9
A 0 means its whole block is empty, and a 9 means all nine cells are filled. Clues on the edge work the same way with fewer cells, so a 4 in a corner fills the whole corner block.
Compare neighboring clues
Two clues side by side share six cells. The difference between them has to come from the three cells each sees alone, which often settles those cells at once.
Mark the empty cells too
Marking known-empty cells makes the remaining counts easy to read. Most mistakes come from losing track of which cells are still open.
Frequently asked questions
Is mosaic the same as fill-a-pix?
Yes. Mosaic, fill-a-pix and paint-by-numbers logic are names for the same rules. In picture versions the filled cells draw an image; here the boards are generated, so the result is a pattern.
Do I ever need to guess?
No. Every board has one solution that you can reach from the clues alone.
How is it different from minesweeper?
The number rule looks alike, but mosaic clues count their own cell too, and nothing explodes. You fill cells instead of avoiding them.
