Abstract: A kidney shaped number generator for randomly placing numbers in Keno and other lottery number games comprising: a base, a set of numbered disks on opposite sides of the base, each of said disks having numbers on opposite sides of the disk, a mask overlying each of the sets of numbered disks and a transparent cover on opposite sides of the base for enclosing the numbered disks. Each of the masks has a window through which selected sets of numbers are exposed. An important feature of the invention is that the generator can be used in different lotteries by merely changing the masks and amounts of numbered disks. In a first embodiment, the masks are labels adhesively applied to outer or inner surfaces of the transparent outer covers. In a second embodiment, the masks are thin sheets of materials with graphics between the numbered disks and transparent outer covers.
