This game is tic tac toe where both players play with X's. There is a grid of 3 by 3 spaces, and the players take turn to mark a space with an X. The one who marks a space which causes 3 X's to line up horizontally, vertically, or diagonally loses. In higher levels there are multiple 3 by 3 boards. The players can choose to mark any of the boards. When a board has a line formed, it is removed and can no longer be marked. The player who forms a line in the last board loses. There are tactics for different number of boards where the first mover or the second mover is able to force a win. The more levels you finish and the faster you finish, the higher your rank.
