FAQ
What is a Nonogram?
A Nonogram (also called Picross or Griddler) is a logic puzzle where you fill cells in a grid based on number clues for each row and column. The numbers indicate groups of consecutive filled cells. When solved correctly, the filled cells reveal a picture.
How do the number clues work?
Each number represents a group of consecutive filled cells in that row or column. Multiple numbers mean multiple groups separated by at least one empty cell. For example, "3 1" means a group of 3 filled cells, at least one gap, then 1 filled cell.
