HN comment orderI thought this was kinda neat so I taught a computer how to do it: https://github.com/lvh/regex-crossword/blob/master/src/lvh/r... Right now, it works using a logic programming engine (core.logic, essentially miniKanren), generating a bunch of strings that match the regex, and then applying them as constraints. If I were to improve it, I'd parse the regex, walk the parse tree, and assign constraints that way. (There's already a regex parser in there: that's how the string generation works.) That was my first…

I believe that the 6th and 7th mobile puzzles are unsolvable with the provided character sets. Am I missing something?
Neat little game. One suggestion I have though: if the puzzle doesn't validate, signal the lines that don't validate properly.
