#2 – Block Zenn 1
This game is played the same as ZENN, but if a player hits his opponent’s Zenn blocks he is entitled to another shot. However, only one extra shot per turn is allowed. Hence, on one’s initial shot it would be good strategy to rebound the chip slightly off the Zenn blocks to “set up” for an easy Zenn.
#3 – Block Zenn 2
This game is played like ZENN but players try to avoid hitting their opponent’s Zenn blocks. One point is awarded to the opponent if the player hits his Zenn blocks. One point is still given for a normal basket, but 6 points are given for a “Zenn” (The chip may hit the Zenn blocks on a “Zenn’;:). If a player scores a basket by ricocheting the chip off his opponent’s’ Zenn blocks no point is scored by the shooter, and the opponent places the chip between his Zenn blocks and play continues.
#4 – Block Zenn 3
The game is played like ZENN , but points are scored by “Zenns” or by hitting your opponent’s Zenn blocks. The Zenn blocks must be hit by ricocheting the small chip off any of the four sides of the board (Fig. 4). Three points are given for a “Zenn”, and 1 point is given for hitting the blocks. No points are given for baskets other than “Zenns”. After a “Zenn” the chip is placed between the Zenn blocks of the player scored upon. That player then attempts a “Zenn”. After a single point is scored, the player scored upon shoots the chip from where it lies. A chip which is shot into the basket is placed between the Zenn blocks of the player whose turn it is to shoot next.

#5 – Block Zenn 4
The game is played like ZENN , but points are scored by “Zenns” or by hitting the BACK of your opponent’s Zenn block without putting the chip into the basket. If the chip is shot into the basket (other than by a “Zenn”) your opponent receives 1 point. Two points are given for hitting the BACK of your opponent’s Zenn block (Fig. 5), and 3 points are given for a “Zenn”. After a score (either 3, 2, or 1 point score) the small chip is placed between the Zenn blocks of the player scored upon. That player then attempts a “Zenn”.
