Abstract

Abstract A basketball game is played on a circular court outlined by concentric circles. A pole is removably mounted in an upright position at the center of the court. On top of the pole is a horizontal hoop supported by removable bracket arms carried by the pole. A tapered net basket with a closure ring at the bottom is suspended from the hoop inside the bracket arms. A manually operable ball ejection mechanism including an axially vertical slidable rod is carried by the pole. The rod is spring loaded and extends through the ring for ejecting the ball after retraction to compress the spring.
