Abstract: An apparatus and method for selecting random numbers, particularly suited for the purpose of placing wagers. The apparatus includes a funnel-shaped chamber from which balls are propelled by a stream of air from a motor driven fan beneath the chamber. The apparatus includes a transparent dome enclosing the chamber and a transparent, perforated tube into which the balls are propelled by the air and retained in the order of their arrival into the tube. The balls are numbered and distinctively colored for easy visibility and identification. An adjustably positionable finger enters the interior of the tube through one of the perforations to retain the pre-determined number of balls in the tube.
