By Size 20×20 Nonogram 20×20 Nonogram 35×35 Hard — Set 36

A nonogram (also called picross, griddler, or hanjie) is a logic puzzle where you shade cells in a grid according to number clues on each row and column. When complete, the shaded cells form a pixel art picture.

Begin with the row or column that has the most filled cells (longest clues). Fill all cells that must be filled regardless of clue position, then eliminate cells that cannot be filled. Work iteratively until the puzzle is solved.
