About Nonogram Hub
Nonogram Hub is a free online destination for nonogram puzzles — also known as griddlers or Picross. Every day we publish one new daily puzzle: fill in the grid using the row and column number clues, and a hidden picture appears once every line matches its clue.
The site is built around three things: a fresh daily puzzle you can solve in a few minutes, a streak and points system that rewards coming back day after day, and a calendar/archive of past puzzles so you never really miss one. If you'd rather play at your own pace, practice mode generates a fresh board — any size, any time, no streak on the line.
We also maintain a step-by-step solving guide for players who are new to nonograms, covering everything from reading your first clue to the overlap method used on harder boards.
Nonogram Hub is free to play, with no account required to solve a puzzle. Creating an account lets your streak, points, and completed-puzzle history sync across devices instead of staying only in your browser.
What you'll find here
The daily puzzle is the heart of the site, but it's not all there is. Practice mode lets you generate a fresh board on demand in a range of sizes — from a quick 5×5 up to a meatier 20×20 — with no streak on the line, which is the best way to warm up or to just keep playing once you've finished the day's puzzle. Alongside that is a growing catalog of hand-picked puzzles sorted into themes like animals, food and drink, everyday objects, board games, and zodiac signs, so you can pick a subject you enjoy rather than take whatever comes up.
For learning and reference, there's a full step-by-step solving guide, a comparison of the different names the puzzle goes by (nonogram, Picross, griddlers, hanjie), an FAQ, and an online solver you can point at a puzzle you're stuck on. If you're curious how the puzzles themselves are built, the "how we make our nonograms" page walks through the whole pipeline.
Puzzles you can actually solve
A nonogram is only fair if it has exactly one solution and can be reached by logic alone — no lucky guessing. That sounds obvious, but it's surprisingly easy to generate puzzles that quietly break one of those rules. So every puzzle we publish is checked by our own solver first: it confirms there's a single unique solution and that the puzzle can be worked out step by step without trial-and-error, and anything that fails is thrown out rather than fixed up. On top of that automated gate, a person looks at the ones headed for the catalog to make sure the finished picture actually reads as what it's meant to be.
We think that quality bar matters more than sheer quantity. A hundred puzzles that all solve cleanly are worth more than a thousand where some leave you second-guessing whether you made a mistake or the puzzle did.
Free, and in your language
Nonogram Hub is free to play and always has been. You don't need an account to solve any puzzle, including the daily; an account only exists so your streak, points, and history can follow you between devices instead of living in a single browser. The site is available in five languages — English, Ukrainian, Polish, Spanish, and German — so the interface and the learning material aren't English-only.
