It is a classic Tic-Tac-Toe game.
In this version of the game you can play both with a computer and with a real opponent. Choose the difficulty level to play with the computer and test your abilities depending on your level of experience.
In addition, if you are playing with a real opponent, you can set a certain time for each turn. This feature makes it possible to control the duration of the game and prevents the endless waiting of another player.
