  1. The game is played on a grid that’s 3 squares by 3 squares.
  2. You are X, your friend (or the computer in this case) is O. Players take turns putting their marks in empty squares.
  3. The first player to get 3 of her marks in a row (up, down, across, or diagonally) is the winner.
  4. When all 9 squares are full, the game is over. If no player has 3 marks in a row, the game ends in a tie.

Tic-tac-toe (American English), noughts and crosses (Commonwealth English), or Xs and Os (Irish English) is a paper-and-pencil game for two players who take turns marking the spaces in a three-by-three grid with X or O. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner. It is a solved game, with a forced draw assuming best play from both players.
