When I was a kid, learning programming, I toyed with writing my own logic-puzzle solver program, but the challenge of turning words on their side defeated me at the time. Now it's just one line of CSS. :-)
Would you be interested in adding logic puzzles / logic grid puzzles? They're not that hard to create automatically; spend long enough on https://logic.puzzlebaron.com/ and you'll definitely notice that those puzzles are being auto-generated by an algorithm.
