Tic Tac Toe is a very solid game. So much so that I made like 10 billion versions of it just to have fun while playing Tic Tac Toe with the lads.
Just your regular tic tac toe 1v1 online where you and one other friend fight to the death, while in the safety of your own homes. Did I mention the online part, that took a long time.
I have made this Ai based on the Minimax decision rule and I cant beat it, no matter what I do. It is sad, I cant beat my own creation... The Ai uprising is upon us, run while you can.
