How to Play Tic Tac Toe

- Players take turns placing one symbol at a time.
- Complete a horizontal, vertical, or diagonal line to win.

How Ultimate Tic Tac Toe Works
Ultimate Tic Tac Toe uses nine small 3×3 boards arranged inside one large 3×3 grid. The cell you select sends your opponent to the corresponding mini-board for their next move.
Win a mini-board to claim its position on the large grid. Claim three mini-boards in a horizontal, vertical, or diagonal line to win the Ultimate Grid.
