This is similar to regular tic tac toe except that you can make alternate moves. Each player has 3 moves to initially make. Then they move around till one player wins.

Tic Tac Toe is a great mind game dating back to Ancient Egypt. This style is very popular in many parts of the developing world.
This style of Tic Tac Toe has not been written before.
