  • Patent number: 4236716
    Abstract: A box supports two playing fields which slope downwardly from opposite sides thereof toward a switch bar along the exposed inner side of each field for energizing a "spill" display light at the end of each field when a player fails to score with a ball rolling between two gently sloping cues from dwell notches thereon, upon skillfully opening the handles of the cues that rest on a support, and are connected at their outer ends, which are bent down to rest on the playing field, by one of three dropping the ball into triangularly arranged sockets that are assigned different score values ranging from a minimum to a maximum as the distance from the back of the field increases, with three balls per turn per player, two, for example.
