In the event of any of the following situations, the ball will be counted, but the knocked-down pins will not count:
– the player has committed a foul;
– the ball bounces off the back cushion;
– the ball is thrown off the track before it reaches the pins;
– the machine, setting the pins, knocks down one of them;
– pins that were knocked down, flew out of the track, bounced back, but remained standing, are not considered knocked down.
