Nonograms
Follow the clues, fill the squares, and let a hidden pattern come into view.
How to play Nonograms
- Each number describes a consecutive run of filled squares in that row or column.
- Keep at least one empty square between separate runs. Runs appear in the order shown.
- Use an X to mark a square you know is empty. All row and column clues must agree.
Make your move
Choose Fill or X, then tap or drag across squares. Use the zoom control on larger boards. Choose Pan to move around an enlarged board without changing squares.
