Happy Labor Day, everyone! In celebration of the time off, here's a Problem of the Week that's about a fun game... or rather, a not-so-fun game, as you're going to figure out in the Problem itself!
You can find my solution after the break, like always.
What did you think of the problem? Are there any versions of tic-tac-toe you know that are more interesting to play? Tell us in the comments!
