About Mosaic
Mosaic (also called ArtWork or Minesweeper-like) is a grid-filling puzzle where numbered cells act as local density clues. Each number tells you how many cells within its 3×3 neighborhood — including itself — are filled (shaded). Your task is to shade the entire grid consistently with all the clues.
The 3×3 neighborhood is key: edge and corner cells have smaller neighborhoods (6 or 4 cells respectively), making clues near the grid boundary more constraining. The overlapping neighborhoods of adjacent cells create rich deductive interactions — a single filled cell simultaneously updates the count for every clue cell whose neighborhood includes it.
Mosaic is visually engaging because filling cells gradually reveals a picture or pattern. Unlike Nonograms, where the image emerges row by row, Mosaic builds up organically from individual cell deductions scattered across the grid. It’s a uniquely tactile solving experience.
Start with clue cells at 0 (all neighbors are empty) or at their maximum (all neighbors are filled). These force immediate placements and create the anchors from which the rest of the grid fills in.

What is Mosaic?
Mosaic is a grid puzzle where numbers indicate how many of the cells in a 3×3 neighborhood (including the numbered cell itself) should be shaded. It combines Nonogram and Minesweeper logic.
