This is similar to regular tic tac toe except that each player has 3 moves to make. Then, they move around till one player wins.I have also uploaded a youtube video for that. http://www.youtube.com/watch?v=UoCuDTysjqsThis is the only game that does that on the market. So, I hope you will tell your friends and even play it with your friends at school. Tic Tac Toe is one of the world oldest games dating back to ancient Egypt around 4000 B.C.Enjoy!
