Free online Nonogram: use row and column number clues to fill cells and reveal pixel pictures, with mistake counter and cross-out marks

How to Use
Nonogram (Picross / Griddler) is a logic picture puzzle. Numbers beside each row and column give the lengths of consecutive filled runs — '3 1' means a run of three, at least one gap, then one. Deduce every filled cell to reveal a hidden pixel picture. Fill with a click, mark certain-empties with ✕, drag to paint runs, and completed rows/columns fade automatically. Six themed pixel pictures appear at random; mistakes and time are tracked live.
FAQ
What is a Nonogram?
A Nonogram (a.k.a. Picross, Griddler or Japanese crossword) is a logic puzzle where number clues define filled cells; solving reveals a pixel picture. It became a worldwide hit in the 1990s.
How do beginners get better at Nonograms?
Start with full rows (10) and empty rows (0), then lines where a large run plus known ✕ cells pin the run's position; keep cross-checking rows against columns.
Are wrong fills flagged?
Yes — filling a cell that contradicts the solution counts as a mistake (with a sound cue) but is not auto-corrected; the hint button points to a cell that must be filled.
