[JAVA] Tic Tac Toe 02-17-2013, 09:00 PM
#1
I just made this because I was feeling bored today. It behaves strangely once in a while whose reason I'm still trying to figure out. Other than that, it works alright I guess. You have to play Tic Tac Toe against AI. It is not difficult to win, but don't take this AI lightly 
Cheers

This code could be shortened a lot. I don't know much about the graphics because i'm not a Java dev. I might be getting into Android programming soon however. But for the logic, I came up with some good algorithms, that would work for any sized board if needed, and any number of needed player markers in a line.
