A more advanced version of the basic Tic-Tac-Toe game.
In Ultimate Tic-Tac-Toe, the board game is composed of
nine Tic-Tac-Toe boards arranged in a 3-by-3 grid. Players take turns playing in the smaller boards until one of them wins
in the larger board.
Once a player has won the larger board, they are presented with the option to play again.
