Unbeatable TicTacToe

Relive your childhood moments in this augmented version of the classical game TicTacToe.

Play against a friend on 3x3, 5x5, and 7x7 boards; or test your skills against an unbeatable AI (which you can dumb down to feel smarter).

The AI was built using the Minimax Algorithm with Alpha Pruning. If anyone is able to beat it, send me a video and I will send back a very special gift!
