The NineTacToe playsheet depicts nine Tic-Tac-Toe boards with numbers in the spaces; the numbers 1-27 each appear three times throughout the boards. Players take turns choosing a number and marking their symbol in the three spaces where it appears. In effect, each number choice is a play on three of the nine Tic-Tac-Toe games at once. The object is for a player to win a majority of the nine sub-games.
