#61 – The Wall 1
Players alternate setting up a “wall” of big chips and attempting to penetrate it and score a basket. The game may be played with from 5 to 8 big chips and 1 small chip. The winner is the player who scores a basket in the fewer number of shots of the small chip. Play starts with a player setting up a “wall” of large chips anywhere on his side of the center line without any chip overlapping the basket. The player trying to penetrate places the small chip between his Zenn blocks and shoots towards the “wall” (Fig. 25). After the small chip is shot, the player with the large chips shoots one of his chips, but he must propel it initially forward (towards his opponent’s basket). The large chip is allowed to ricochet off the back and bounce back towards the player’s own basket. Players alternate shots. If a big chip goes off the board it stays off. If the small chip goes off the board it is placed between the Zenn blocks of the player shooting the small chip. All chips may hit each other. If the small chip is knocked in, or is shot into the basket of the player shooting the small chip, the small chip is placed between the Zenn blocks of the player shooting the small chip. A shot is added to his total number of shots needed to score a basket.

#62 – The Wall 2
This game is played like THE WALL 1, but the player with the big chips may propel them forward or backward. This exception makes it much more difficult to penetrate the wall and score a basket.
