X or O

Features X or O

X or O, noughts and crosses(Tic-tac-toe) is played on a three-by-three grid by two players, who alternately place the marks X and O in one of the nine spaces in the grid.
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.
