The game is played like ZENN, but, before a player shoots for a basket, his opponent may place a large chip anywhere on his Zenn line and shoot it toward the small chip in order to prevent a basket from being made (Fig. 20A). The large chip may hit the small chip and vice versa. However, if the large chip knocks the small chip off the board or into either cup 3 points are awarded to the player whose small chip was hit. When the small chip is being shot from between the Zenn blocks, the defensive player must bounce the big chip off one of the side bumpers in order to block the shot of the small chip (Fig. 20B). After every shot of the small chip the large chip is removed from the board. Players alternate shooting the large and small chips.
