Tic Tac Toe is a classic game where you must get 3 Xs or Os in a row, column or diagonal.
Optimal play often leads in a draw because each combination can be blocked by the opponent.
The logo shows a fork where the red O player can win with 2 different moves (left center or bottom center).
The 'hard' difficulty is unbeatable while the 'medium' and 'easy' difficulties can be beaten.
You can choose to play first (blue X) or let the opponent play first (meaning you will get the red O).
This game is also known as Noughts and Crosses or Xs and Os.
