#70 – Knock Zenn 1
Player A starts with his large chip behind his Zenn line by his own basket while Player B starts with his large chip (different color) behind his Zenn line. A small chip is placed in the center circle (Fig. 27). The object of the game is to knock the small chip into one’s OWN basket by using the large chip as a “knocker”. One point is given for this score. If Player A knocks the small chip into Player B’s basket, Player B gets 1 point. If Player A knocks Player B’s large chip into either basket, 2 points are given to Player A. If Player A shoots his own chip (large) into either basket, Player B gets 2 points. After each score, play begins as it did in the beginning of the game. The game is played to 20.
