ABSTRACT:
A pressurized plenum or air chamber is separated by internal walls to form slots, holes or the like. The separated chambers may be either in gas pressure communication or entirely separated from each other. Game piece manipulation devices operate a controller via these slots or holes. The upper surface of the plenum is perforated to enable the pressurized air to escape and form a boundary layer of air at the playing surface. The air pressure may be controlled, at the perforations, in order to form different zones of surface friction.
