Nonograms, also known as Picross, Griddlers, or Hanjie, are logic puzzles where you fill in cells on a grid based on number clues for each row and column. The numbers indicate groups of consecutive filled cells, separated by at least one empty cell. Solving the puzzle correctly reveals a hidden picture — that's the magic of nonograms!
Each row and column has a set of numbers as clues. For example, "3 1" means there is a group of 3 filled cells, then at least one empty cell, then 1 filled cell. Use logic to determine which cells should be filled and which should be left empty. Mark cells you know are empty with an X to help you keep track.

Start with Beginner (5×5 to 7×7) puzzles to learn the basics, then progress through Easy (8×12), Normal (13×17), Hard (18×22), and Expert (23×25) as your skills improve. Each puzzle reveals a unique pixel art picture when completed.
