Hello,

I have a group assignment that I have to do. We have to write a Tic Tac Toe game. One person in my group has managed to write the code for a multiplayer (human -vs- human) game and I managed to write a code for a single player (human -vs- computer) game.

My problem is, now we want to merge the two games with options to pick which game you would like to play. However, the games were written totally different styles and I can't get them to work, so I am turning to you for help.

Here is the multiplayer game

Any ideals as to what Im doing wrong, after I get the two games running together I will add options to choose the type of game to play.

Thanks in advance...

re: Tic Tac Toe Game Help, Please....

Wby bother to merge the code? I mean, both games work, right?

So why not:

  2.     if (SinglePlayer == true)
  3.      {
