Wild tic-tac-toe

Wild tic-tac-toe is an impartial game similar to tic-tac-toe. However, in this game players can choose to place either X or O on each move.[1][2] This game can also be played in its misere form where if a player creates a three-in-a-row of marks, that player loses the game.[3]

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]
