Wild tic-tac-toe

However, in this game players can choose to place either X or O on each move.

[3] Wild tic-tac-toe is played on a 3-by-3 board by two players, who take turns placing an X or an O on any unoccupied square.

[4][5] The player who completes a straight or diagonal line of 3 X's or 3 O’s wins.

[3][6] In this version of the game, the player which makes the first move can always win.

[3][5] The second player can force a draw by playing a mark opposite of the opponent's mark and choosing X if the opponent chose O (or vice versa).
