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.
