I couldn't resist making that pun.
Anyway, this is TicTacToe V2.0, or TicTacTWO!.

I've compacted the actual play sequence, made the AI waaay smarter and actually implemented a win method!

Pretty proud of this, to be honest.
(if you find a bug while playing, please tell me)

Update:
made AI better
Added tie check

Code:
