Abstract
A rotatable ball momentum transfer assembly for an amusement gam, such as a pinball machine includes an impact ball mounted to an inclined playfield and a shaft mounted to the playfield proximate to the impact ball. A travel ball is coupled to the shaft such that the travel ball rests against the impact ball during gameplay to receive momentum from the impact ball when the impact ball is struck by a game ball, causing the travel ball to at least partially rotate about the shaft. In one example, the travel ball rotates in a fixed arc towards one of two resting positions on either side of the impact ball. These two resting positions both open or close different shot paths available during gameplay.
