Hi

I'm making a tic tac toe game for a school assignment and i already managed to get 1vs1 working and vs cpu is sometimes working great but sometimes not .
Can someone take a look at it please?
The way the computer think is random and the names should be selfexplained cause i use prefixes.
I'm not that good at programming yet i have only done it a half year now.
