What can I tell you about Tic-Tac-Toe that you haven't heard before? I used to play Noughts and Crosses on the school bus when the windows were fogged-up with condensation from child-breath. Every day. By myself. I admit it got a little repetitive. I tried it blindfold once, but that only made me realise I needed to kick the habit.
Thankfully this version allows you to play with someone else, if you know such a person. If you're lacking an opponent, the computer will gladly play you instead, just like in that '80s movie WarGames, but without the looming threat of a global thermo-nuclear war. Which I suppose is only a good thing.
