I've been getting really into nonograms lately. However, I can't get a great source for difficult nonograms.
One app which I play on generates puzzles, which are decently tough, but never really require any thinking, just scratchwork. And I've got that down to a science by now.
The other app which I play on relies on user-created nonograms, but to be quite frank, most of those just plain suck :/. If you sort by "difficulty," you just get these massive 30x30 puzzles that aren't hard, just boring.
This might be a bad question. For sudoku, I had a similar problem. The apps I was on were just feeding me randomized puzzles solvable with naive techniques. Then I found logic-masters.de. I think, though, the sudoku setting community only exists because the ruleset of sudoku affords advanced techniques to set incredibly probing puzzles. Maybe, because nonograms have a simpler rule set, there just aren't that many cool solving techniques to manipulate as a setter, so there's just no setting community for them.
I can't find much of anything on the topic, so anything is welcome!
