Although more than six balls where included with your game, you should never have more than six in play. Adding more balls to the game will cause ball jams and unnecessary down time. Be sure to check occasionally that all balls are clean and free of sticky substances. A calibration guide was included to check the inflation status of the ball. Do not over inflate the balls as they will become stuck in game play.
