We all know that a traditional game of Tic Tac Toe can end very quickly, and once you master the game, well then most games end in a draw. What if you added one simple rule which could make the game fun again. Welcome to Trio Tic Tac Toe! By limiting the number of O's and X's to just 3 per person, it has opened up the game to new possibilities. Once you have placed your third piece on the board, you can then move the first piece you placed down and so forth. Give Trio TicTacToe a go, and see the fun return.
