Academy: Tic-Tac-Toe

One of the world’s most famous pen-and-paper game for two players can
now be in your pocket wherever you go. If there is no one around to play
the game with you, don’t worry: skillful AI players will gladly play
with you in any of the four Tic-Tac-Toe variants available. If a single
3x3 playing field makes you claustrophobic, you'll be happy to try the
new Nine Board game mode that adds a nice twist and more strategic depth
to the game. Prove that you're a worthy Tic-Tac-Toe player by entering
the Tic-Tac-Toe League and advancing from the initial School Club
League, through Academic, City, National, and World Leagues up to the
Super Stars League! Claim the top spot and become the Tic-Tac-Toe Champ!
