Welcome to Nonogram Online, the place to play classic picross puzzles directly in your browser. No installation, no account, no ads getting in the way of your logic — just open the page, pick a grid, and start solving. Whether you're brand new to nonograms or a seasoned puzzler chasing daily challenges, you'll find a board that fits.
What Is a Nonogram?
A nonogram (also known as picross, griddler, hanjie, or paint by numbers) is a logic puzzle in which you fill cells on a grid using numerical clues placed alongside each row and column. The numbers tell you how many consecutive cells must be filled in that line, and in what order. Solve every line correctly and the grid reveals a hidden pixel image — a cat, a flower, a spaceship, or any of thousands of possible designs.
Nonograms have been popular in puzzle magazines since the late 1980s, and the digital format makes them faster, cleaner, and far more accessible than paper.
How to Play Nonograms
The rules are simple, but mastering them takes practice:
- Read the clues. Each row and column has a list of numbers. A clue of
3 2means three filled cells, then a gap of one or more empty cells, then two filled cells — in that order. - Fill or mark. Click a cell to fill it. Right-click (or use the mark tool) to flag cells you've confirmed are empty.
- Cross-reference rows and columns. A cell only belongs in your solution if both its row and column clues agree.
- Use logic, never guessing. Every well-formed nonogram has exactly one solution that can be reached through pure deduction.
- Reveal the picture. When the grid is complete, the hidden image appears.
If you get stuck, you can undo moves, reset the board, or use a hint to nudge yourself forward.

- Expert: Large grids and tricky line patterns that reward careful planning over fast clicks.
The Benefits of Solving Nonograms
Nonograms are more than entertainment. Regular play has been linked to sharper logical reasoning, improved short-term memory, and better focus. Each puzzle is a small, self-contained problem that rewards patience and pattern recognition — a calmer, more constructive way to spend a few minutes than scrolling a feed. Many players also find solving meditative: there's no timer pressure (unless you want one), no opponents, just you and the grid.
Tips for Beginners
- Start with the largest clues. A row of 10 cells with a clue of
8has very few possible positions — fill the overlap first. - Mark empty cells. Knowing where pieces can't go is just as valuable as knowing where they go.
- Work in both directions. Switch between rows and columns whenever you hit a wall.
- Trust the logic. If you feel like you have to guess, look again — there's almost always a deduction you missed.
