Ultimate Tic-Tac-Toe is a fun and smart take on the original game that makes it more difficult. A bigger 9x9 grid with nine 3x3 smaller boards is where you want to win three games of Tic-Tac-Toe in a row. Each player places a mark, and each move changes the mini-board for the next move of the other player. When a player wins a small board, they can mark it in the main grid. If someone wins three mini boards in a row, the game is over. If there are no more legal moves, the game ends in a draw. This version needs strategy, critical thought, and the ability to adapt. It's a fun challenge for people of all ages.
Enjoy!
