A device for the generation of randomly selected numbers or other data. A plurality of small numbered wheels rest upon the surface of a larger base wheel. The larger base wheel is journaled upon a needle in a circular housing. Snap rings retain the base wheel and the smaller numbered wheel within the circular housing. Random data is generated by spinning the base wheel in either direction. The torque of this motion causes the smaller numbered wheels to spin in the opposite direction. When both the base wheel and smaller numbered wheels come to rest, a centrally located indicator determines the number or data selected.
