How to Play
Numbers on each row and column tell you how many consecutive filled cells exist. Multiple numbers mean multiple groups separated by gaps.
Left-click or tap to fill a cell. Right-click or long-press to mark a cell as empty (X) to help you track your logic.
Start with rows or columns where the clue numbers add up close to the grid size — these have fewer possible arrangements.
Press the Check button to highlight any errors. Complete the puzzle with no errors to reveal the hidden picture.
Frequently Asked Questions
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 completed grid reveals a hidden picture.
How do the number clues work?
Each number tells you the length of a consecutive group of filled cells. For example, "3 1" means there is a group of 3 filled cells, at least one gap, then 1 filled cell. The order matters — groups appear left-to-right (or top-to-bottom) as listed.
What difficulty levels are available?
There are three levels: Easy (5×5 grid) for beginners, Medium (10×10) for intermediate players, and Hard (15×15) for experienced solvers. Each level has multiple puzzles.
