Abstract

Gaming apparatus has rotatable disks turning about a common axis of rotation and having annular bands of indicia of different diameters on faces of the disks which extend toward the axis of rotation. A player's winnings are determined by alignment of particular indicia along one or more radii of the disks after a period of rotation. In one form of the invention, the disks are supported, driven and held in a centered relationship with the axis of rotation by gear sets situated at angular intervals around the periphery of the disks which engage gear teeth at the rims of the disks. In another form, the disks are axially spaced apart flat plates of progressively greater diameter extending from drive shafting at the axis of rotation. In another form, the disks are at least partially formed of transparent material enabling viewing of indicia on disks which are behind other disks.
