Tic Tac Toe Game for 1 Player

White chalk lines cut a classroom blackboard into a 3x3 grid. In the Tic Tac Toe Game for 1 Player, the match stays between a human side and the computer, with X and O marks filling the empty spaces until one side claims a line of three.

How to play?

Pick X or O before the round begins, then place that mark in any free square as the computer answers with its own move. Across the board, symbols go down one after another in alternating order, and a round ends when three matching marks line up across a row, a column, or a diagonal. Play again to read the computer’s patterns and test a different plan in the next match.
