How to Play

Ultimate Tic-Tac-Toe adds a brilliant strategic twist to the classic game. The board consists of 9 small tic-tac-toe boards arranged in a 3×3 grid.

• First move: X can play on any cell of any small board.
• The send rule: The position you pick within a small board sends your opponent to the matching board on the big grid. For example, playing in the top-right cell of any small board sends your opponent to the top-right small board.
• Winning small boards: Get three in a row on a small board to claim it as yours on the big grid.
• Free choice: If you’re sent to a board that’s already won or full, you can play on any available board.
• Winning the game: Claim three small boards in a row on the big grid. If no one achieves this, the player with more claimed boards wins. Equal claims = draw.
