Barrier: The international game of tactical momentum As in checkers, the object of the game is to eliminate the opponent's playing pieces by jumping them from adjacent squares. In Barrier, however, the freedom of being able to move forward or diagonally, plus the additional "barrier" rows in the center of th eboard, add an entire new dimension to the game. Players first set up the barrier rows by placing their set of tiles on one by one. These tiles show a diamond shape which signifies which direction a piece may move when in the barrier area. Then players take turns moving their pawns until only one colour remains.
