Tic Tac Toe

How to play

The board is a 3 x 3 grid. Player X always goes first.
Players take turns placing their mark in an empty square.
Get three of your marks in a row — across, down, or diagonally — to win.
If all nine squares fill up with no three-in-a-row, it's a draw.
In one-player mode you play X against the computer (O).
Pick a difficulty before starting: Easy, Medium, or Unbeatable.
