Diagram showing optimal strategy for tic-tac-toe.With perfect play, and from any initial move, both players can always force a draw. In combinatorial game theory, a two-player deterministic perfect information turn-based game is a first-player-win if with perfect play the first player to move can always force a win.
A solved game is a game whose outcome (win, lose or draw) can be correctly predicted from any position, assuming that both players play perfectly.This concept is usually applied to abstract strategy games, and especially to games with full information and no element of chance; solving such a game may use combinatorial game theory or computer assistance.
In wild tic-tac-toe, players can choose to place either an X or O on each move. [7] [39] [40] [41] It can be played as a normal game where the player who makes three in a row wins or a misere game where they would lose. [7] This game is also called your-choice tic-tac-toe [42] or Devil's tic-tac-toe. [citation needed]
A strategy-stealing argument can be used on the example of the game of tic-tac-toe, for a board and winning rows of any size. [2] [3] Suppose that the second player (P2) is using a strategy S which guarantees a win. The first player (P1) places an X in an arbitrary position. P2 responds by placing an O according to S.
