Tic-Tac-Toe A Simple Game


Tic-Tac-Toe is a simple game wherein if you know what you are doing, you cannot lose against your opponent. Also, the other way around, if your opponent knows greatly your strategy and anticipate your next move, you cannot win. However, if both players are good and uses the best strategy the game will end in a draw or tie.

Tic-Tac-Toe is a game played by two players on a 3×3 square grid with each having either an X or an O.  Each player take turns in marking a space on the grid. The objective of the game is for one player to be able to make similar marks 3 squares in a row, whether across, up or down. When all square  (9 in all) on the grid has been filled by Xs and Os then it is game over. In the event that no 3 similar marks in a row has been made, the game is considered a tie or a draw between two players.

A perfect game  (win the game or at least have a tie or draw) is played by a player if he has the choice of putting the first X or O on the grid through the following strategy:

  1. If the player has two Xs or Os in a row whether horizontal, vertical or diagonal and can place the third to get three.
  2. By blocking, the other player has two same marks in a row and the opponent must place the third mark to block the other player.
  3. By making a fork, in this way you create a chance for your opponent to have two threats of you winning the game (having unblocked lines of two marks).
  4. By blocking the other player’s fork, you can achieve this by creating two marks to force the other player to defend their next move.
