Nonogram Database

I am working on a nonogram (aka griddler, paint by number, picross, hanjie, etc) app for Ubuntu Touch.

Along the way, I’ve discovered that there are very few freely distributable puzzles floating around.

In an attempt to change that (for myself and future app developers), I’m collecting the ones I can find in one place.

If anyone knows of any good caches of freely distributable puzzles, please let me know and I’ll add them.

In the meantime, I’m going to strip files from the few open source apps I know about and see if I can get members of some popular nonogram sites to release their puzzles under a free license.

  1. Wouldn’t you be better writing an algorithm to generate such puzzles? Simon Tatham’s puzzle set has one (its “Pattern” app does nonograms, and is open source.) Of course, they’re not necessarily pretty, but maybe you can improve the algorithm 🙂

  2. Well, one of the non-functional appeals of nonograms is the picture that you get at the end. And those are hard to generate automatically, even with an image file as a source, since there are issues of solution-uniqueness and logic-solvability.

    But, admittedly for someone like me that just likes the logic side of things, an automatically generated puzzle would be fine. I might include a generator or at least a link to one in the database documentation.
