Regular game

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.^[1][2][7]

Misere game

This game is exactly like the regular version of the game except the player who creates a line of any three marks (Xs or Os) in a row loses the game.^[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).^[3]
