The “Matthew Broderick Award - This game reminds War Games” Award

Presented by circusblatta to:

Tic-Tac-Toe Squared (Nerdfighter Math)
I've only been programming for less than a year and using PyGame for less than half that time. This was my first PyWeek and I really enjoyed it. So the game I made for this challenge is Tic-Tac-Toe Squared, which is a lot like Tic-Tac-Toe only...squared.
