RegEx Crossword - Sudoku-like Regular Expression Puzzles (regexcrossword.com)

Neat little game. One suggestion I have though: if the puzzle doesn't validate, signal the lines that don't validate properly.

Wow, this is great. I'm shocked that I am finally enjoying something related to regular expressions.

The regex-genex SMT constraint solver ( previously covered in https://news.ycombinator.com/item?id=2579783 ), as demonstrated by @LeventErkok ( https://gist.github.com/LeventErkok/4942496 ), is pretty good at solving this kind of puzzles. :-)

I tried to solve these with regular expressions. Now I have two crosswords.

Fun game. Only thing I can suggest is a way to rotate the puzzle so we don't have to crane our necks / rotate monitors.

Here's a really enjoyable regex crossword from, as I recall, the MIT Mystery Hunt:

This is awesome!

Cool project... I always like the gratification of fake awards, but I'm not sure that yours are actually working... After completing the tutorial, I was informed that I had earned the "baby steps" badge... When going into my achievements however, it still has the `.unearned` class on that badge.
