What is Nonogram?

Nonogram (also known as Picross or Griddler) is a logic puzzle where you fill in cells on a grid based on number clues to reveal a hidden picture.

Controls

• Left click / Tap — Fill a cell
• Right click / Long press — Mark X (cell is empty)
• Drag — Fill or mark multiple cells in a row/column

Reading the Clues

Numbers next to each row and above each column indicate groups of consecutive filled cells. For example, "3 2" means there is a group of 3 filled cells followed by a group of 2, with at least one empty cell between them.

Tips

• Completed rows/columns have their clues grayed out
• Use hints sparingly — each costs 100 points!
• Enable error checking for a gentler experience
• Your progress is saved automatically
