4x4 Tic Tac Toe game in C# Console application

EDN Admin · Dec 11, 2010

Hi, I need some help with my tic tac toe game. I just need a clue about how to make this game so that when you get 3 in a diagonal you win.
 
I know that it is a 4x4 board but you still win with 3 in a row,column and diagonal.
In your answers could you please include some note explaining what the parts of the code you sent does please, Im a student and I need to improve my understanding of everything, Think of me as not knowing anything when you reply.
Thanks to those helpful MSDN user in advance
