Mosaic is a Minesweeper-like puzzle based on a grid with a pixel-art picture hidden inside. Using logic alone, the solver determines which squares are painted and which should remain empty until the hidden picture is completely exposed.

Each puzzle consists of a grid containing clues in various places. The object is to reveal a hidden picture by painting the squares around each clue so that the number of painted squares, including the square with the clue, matches the value of the clue.

Rules of this puzzle can be found here.
