That is a lot of if-else statements. Think you can rewrite this with a more logical approach?
Note: This is not to bash you! If you can think of creating this with another approach, it may help with other types of OOP. Consider using a class for each player as either X or O, and using enum. ::hint hint:: :D
2nd Note: Oh, sorry. This was posted ~2 weeks ago. Likely should not have replied to this thread by now.
