The hidden-picture logic puzzle
Use the number clues on each row and column to work out which cells are filled — and watch a pixel picture appear. Every board is solvable by pure logic, no guessing. Free, instant, unlimited — no registration required.
What is a nonogram?
A nonogram (also called picture cross, Picross or griddlers) is a grid-based logic puzzle. The numbers beside each row and above each column tell you the lengths of the runs of filled cells in that line, in order — for example, "3 1" means a block of three filled cells, then a gap of at least one, then a single filled cell. Cross-referencing rows against columns fills the grid one deduction at a time.
Unlike puzzles locked to one per day, this nonogram is unlimited — pick 5×5, 10×10 or 15×15 and tap "New puzzle" any time, or take the shared Daily Challenge and build a streak.
The rules
- The clue numbers give the filled runs in each row and column, in order.
- Between two runs there is at least one empty cell.
- Fill the cells that must be filled; mark ✕ where you know it's empty.
- Complete every line correctly and the hidden picture appears.

Quick solving tips
- Start with big numbers. A 10-clue in a 10-wide row fills the whole line; an 8-clue pins down the middle 6 cells no matter where the run sits.
- Use the overlap trick. Slide each run as far left and as far right as it can go — cells covered in both extremes are certainly filled.
- Mark the ✕s. Knowing a cell is empty is as valuable as filling one — it splits lines into smaller, easier sections.
- Finished lines first. When a line's runs are all placed, ✕ the rest and watch the crossing lines simplify.
