Ultimate Tic-Tac-Toe

A deeper twist on Tic-Tac-Toe: the board is made of nine small boards, and every move sends your opponent to a specific board.

How to play Ultimate Tic-Tac-Toe

• Win a small board by getting three in a row on it. Win the game by winning three small boards in a row.
• The square you play in decides which small board your opponent must play in next.
• If you are sent to a board that is already won or full, you may play on any open board.
• A small board that fills with no winner counts for nobody.

FAQ

How is Ultimate Tic-Tac-Toe different from the classic game?

What happens if I am sent to a finished board?

If the board you are sent to is already won or full, you may play on any board that is still open.

Is Ultimate Tic-Tac-Toe a solved game?

Unlike classic tic-tac-toe, there is no simple strategy that guarantees a draw, so games stay interesting even between strong players.
