The target, which spins when struck by a projectile 14 moving across a playfield 12, has means sensing the number of rotations and the direction of rotation in order to assign a player a score. The target has wings 22 extending outwardly from a shaft 20 and a detectable member 26 mounted eccentrically on the shaft. A pair of spaced-apart sensing means, e.g. 28, are disposed adjacent the sweep of the detectable means for sensing passage of the detectable member, and means associated with the sensing means interpret the number of rotations of the shaft and the direction of rotation, according to the number of times the detectable member passes by the sensing means and the order in which it passes, and provide a score. <IMAGE> |
