About NonogramGo
NonogramGo is a free online Nonogram (also known as Picross, Hanjie, or Griddlers) game. It runs entirely in your browser — no download, no account, and no sign-up required. Open the site, pick a size, and start solving.
What makes it different
- Unique-solution puzzles. Every board is generated and verified so that it has exactly one logical solution — you never have to guess.
- Real difficulty levels. Easy (5×5), Medium (10×10), Hard (15×15), and Expert (20×20), with larger grids available under “More sizes—
- A shared Daily Challenge. One seeded puzzle per US Eastern calendar day, the same for every player.
- Honest help. Hint applies a single logic deduction; using it disables ranking for that run. Undo/Redo, Auto-fill, and Mark X are always available.
- Fast and lightweight. The whole game is a small amount of HTML, CSS, and JavaScript. It loads quickly even on mobile connections.
