The incompatible tag is used on puzzles that are either extremely poor, or a duplicate like another spiral puzzle. It is the only way to remove puzzles without dishing out community bans.

If you feel your puzzle does not fall in these categories then I can take a look and remove the flag .

I don't think it is extremaly poor, because it is one of my hardest 5x5 puzzles (as far as 5x5 puzzles can be hard). I tried to invent some nontrivial 5x5 puzzle and I get this puzzle. I don't think it is duplicate, because I get just some random pattern.

I am talking about that puzzle: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1275887736

I'm away from home at the moment on a business trip. I'll check this out on Friday when I get back. It is possible it was a mistake on my part.

Sorry about that.
