The board is a three-by-three grid of mini tic-tac-toe boards. Win a mini board to claim that cell on the mega board. Your move in a mini board determines which sub-board the opponent plays next. Chain victories across small boards to line up three on the big board. Three AI levels — Easy, Normal, and Hard — determine how many moves the computer calculates ahead.
Win nine mini boards to claim the giant tic-tac-toe victory.
