Nonograms (Hanjie)

[RokCoder]

You only need the white blocks to be set for completion.

Yep that was what I assumed with your first post, then I started wondering why 2 shades of dark. Glad you made the change, the player can then focus on the runs of white.

I've yet to encounter an unsolvable. I suppose with higher numbers it gets much harder to place the smaller runs.
But I think if you match all the runs on rows and cols you will have solved the puzzle even if more than one solution exists.
The way I set it up, you only have to match all runs in the rows and cols, there is only that pattern saved as solution.

I will check your latest out, maybe figure a way to expose a picture?

You make a very valid point. They may well all be solvable (though I don't know for sure). There are a lot that require guesses if you go that route but, hey, why not

It's off-topic for this forum but I did my original Nonograms project in Scratch. The BASIC one is much better written and far more optimised but the original has pictures to solve (as well as random creations).
