How to Play
- Read the numbers beside each row and above each column.
- Each number is a run of filled cells in that line.
- Separate multiple runs with at least one empty cell.
- Tap a cell once to fill it, tap again to mark it with X, and tap a third time to clear it.
- Explain Move shows a deduction before you apply it. Undo cancels your last cell change, including an explained move.
- Your current puzzle saves in this browser. Restart clears this attempt; New Puzzle opens a different picture.
- Match the number clues in every row and column to finish the puzzle. The Lines score tracks matching rows and columns; one matching line alone does not prove all its cells are correct.
About Nonograms
Nonograms are picture logic puzzles, also called griddlers or Japanese crosswords. The numbers around the grid describe the shape of the hidden picture, and each correct deduction turns the blank board into pixel art.

A Simple Brain-Friendly Game for Deduction and Focus
Nonograms are good puzzles for short focused breaks because every mark should follow from the clues. You need to count carefully, compare rows and columns, remember confirmed empty cells, and build the hidden picture step by step.
The rules are simple enough for many ages, but the puzzle still rewards logic, patience, visual reasoning, pattern recognition, and careful problem solving.
Nonograms Strategy and Tips
What makes Nonograms interesting?
A Nonogram gives you all the information you need, but not all at once. One certain mark in a row can unlock a column, and that column can make another row clear. The puzzle is about patiently connecting those little certainties.
Simple Nonograms strategy
A useful beginner strategy is to start with the biggest row or column clues. Large clues often overlap no matter where the run begins, which gives you safe filled cells. Then use those confirmed cells to unlock nearby rows and columns without guessing.
Good habits for solving the grid
- Start with rows or columns that have large numbers.
- Look for clues that must overlap no matter where the run begins.
- Mark confirmed empty cells with X so you do not recount them later.
- Use completed rows and columns to check nearby clues.
- Avoid guessing until every clear deduction is exhausted.
Why people enjoy playing Nonograms online

Solving Techniques for Nonograms
Use these techniques to find cells that must be filled or empty. Larger grids may require more advanced deductions.
- Overlap method: compare every possible position of a block. Cells covered in every position must be filled. For a single clue of 7 in an empty 10-cell row, cells 4–7 are guaranteed filled.
- Edge reasoning: the first block does not have to start at the edge. Use confirmed cells and empty marks to narrow down where it can fit.
- Space elimination: if completed clue blocks account for all available cells, every remaining cell must be empty.
- Cross-referencing: when you fill or mark a cell from one direction (row), immediately check whether that cell's column clue changes the picture too.
- Mark confirmed empty cells with X to keep track of the remaining possible block positions.
Why Nonograms Are a Uniquely Satisfying Puzzle Format
Each filled cell contributes to a hidden picture. Compare row and column clues, mark what you can prove, and watch the picture emerge as you solve.
