# Regex crossword

I can't believe this old-but-gold piece hasn't been shared here. It's a regex crossword puzzle!

Here's a nicely printable PDF.

Kudos for this one goes to a competition held by MIT in 2013. The answer to this particular puzzle is also listed there, so this isn't much of a competition - I'm just sharing something nice to play with that I myself enjoyed immensely. :)

• Does each regex have to consume the entire row/column? Or does the regex just have to match at least once? – plasticinsect Aug 13 '19 at 19:56

• @ArnaudMortier - Is that the one that says (DI|NS|TH|OM)*? Then yes, it's correct. It matches the regex. – Vilx- Aug 13 '19 at 21:29

I loved this puzzle. I'm super impressed with @Conifers who completed it in 2 hours. Took me something closer to 5 hours, though I did it in burst of 30 minutes. Here's mine:
