Abstract: An apparatus for randomly selecting combinations of numbers for lottery-type games of chance. In the preferred embodiment, the invention comprises an adaptor hood which sits on a downsized, bingo-ball blower. The hood includes a lower access hole to receive lightweight numbered balls from an underlying blower chamber in which the balls are blown about; a spring-biased selector arm that normally straddles and blocks the hole, but which can be manually pivoted to allow a ball to pop up the hole and which can then be released to spring back and kick the ball away during its return movement; an adjacent inclined ramp that receives the kicked ball to feed it downwardly; and a clear display chute that catches the balls from the ramp and allows them to be viewed by a user.To operate the selector, a player pulls a control end of the selector arm that extends beyond the hood. This causes a ball to be blown up into the adaptor hood and trapped under a finger mechanism.
