Mosaic is a picture puzzle like a nonogram, but the clues sit inside the grid. Each number tells you how many squares in the 3×3 block centred on it are shaded — the number’s own square counts too.
Start with the 0s (nothing shaded around them) and the 9s (everything shaded), and numbers on the edge whose block is smaller. Then look at neighbouring numbers whose blocks overlap.
Finish the puzzle to reveal a colourful picture — or choose random patterns for pure logic.

Shade squares so that every number equals the count of shaded squares in the 3×3 block around it.

Nonogram clues are outside the grid and describe whole rows and columns; Mosaic clues are inside and count only their neighbours.
