Tic-Tac-Toe is a two-player game. The first player selects one of the cells in a three-by-three grid to place an ‘X,’ finishing their turn. Next, the second player places an ‘O’ in their chosen cell on the same grid. The players take their turns, each trying to get a three of their symbols to align horizontally, vertically, or diagonally.
In this version, the player who initiates the game is always X. The second player — whether a guest on the same device, a second player logged in remotely, or one of the artificial intelligences included here — is accordingly O. All games against any opponent will be logged in your personal statistics.
