Fill-a-Pix (Mosaic): how to play, rules & tips

Play Fill-a-Pix, also called Mosaic, free online. Each number tells you how many of the nine squares around it are filled. Use logic to fill the right ones and a hidden picture appears.

How to play Fill-a-Pix (Mosaic)

Every number counts the filled squares in its 3x3 block: the numbered square itself plus its eight neighbors. On the edge of the grid the block is smaller, so a corner clue covers only four squares.

Tap a square once to fill it, again to put a cross on it (a square you know is empty), and once more to clear it. Crosses are just notes for you.

The puzzle is solved when every number is satisfied. The filled squares then show the hidden picture.

Fill-a-Pix boards and difficulty

There are 10 boards: four easy 5x5 grids, three medium 6x6 grids and three hard 7x7 grids. Pick any board from the list.

Each board was checked by a solver to have exactly one solution. The free Hint is always correct, Clear wipes the board, and your best score per board stays banked even if you start over.

Fill-a-Pix tips

A 0 means its whole block is empty. Cross out every square around it.
A 9 means its whole block is filled. On an edge, a 6 does the same, and in a corner a 4 fills all four squares.
Compare two clues next to each other. Their blocks share six squares, so the difference between the numbers tells you about the three squares only one of them covers.
Once a clue has all its filled squares, cross out the rest of its block. Once it has as many open squares as it still needs, fill them all.
Work outward from solved areas. Each new fill or cross often finishes a neighboring clue.
