so here’s something we stumbled some months ago which made us happy: regexcrossword.com is a geeky crossword puzzle made of regular expressions.

the idea is cleverly simple: find the character that fits both the patterns on the vertical and horizontal clues. they start with super easy crosswords on a tutorial of sorts, and then advance to more complicated concepts and grid-shapes which are trickier but just as much fun to figure out.

we’ve done all of them now, but if you’re up to a challenge or a way to brush up on those skills, give it a go! :)
