ABSTRACT:
A machine for random distribution, particularly for use in a gaming machine such as a bingo type game, utilizes a plurality of lightweight spheres such as ping pong balls, in two colors such as black and white. The balls are contained between two parallel planes spaced apart slightly wider than one ball width, at least a part of the front plane being transparent. The space between the two planes is divided into a mixing section and a holding section, separated by a narrow channel which may be at the bottom of the machine. Motors in both sections create air movement in the respective sections so as to mix the balls in the mixing section and then lift the balls in the holding section, into a pattern or matrix of the black and white balls. The pattern of stationary balls reveals whether the player has won a game of chance such as bingo, wherein all balls of one color would be in a single line. In a preferred embodiment the blowers are arranged to exhaust air from both chambers or sections thus drawing a vacuum through the chamber. The air motors are activated alternatively.
