    I need to know how many winning combinations there are in this for the player that goes first.

    Anyone know how many?

    Cheers in advance

    Erk, i'm bad at phrasing questions. What i mean is all the winninc combinations including the opposite players movements
    X_|_X_|_X
    0_|_0_|__
      |   |
    

    would be one and
    X_|_X_|_X
    0_|___|_0
      |   |
    

    would be another one and so forth.

    If you play that game without making mistakes you can't lose, it's usually always a draw.

  • Registered Users, Registered Users 2 Posts: 2,798 ✭✭✭Funky


    going for 2 opposite corners as first move is the best way to start imo

    Damn.

    And on a side note my 500th post was an attempt to cheat at a game of Naughts and Crosses. How illustrious.

    If you go first you can never ever lose. I developed a system while studying for my leaving cert.

    I think the only way to win is to play against someone who has never played before... and don't tell them how to play :)

    You can actually lose if you go second, the first two moves are manditory... but you may think O not taking the middle in move two is a mistake?
