Abstract

Abstract A game disc is provided for use, in the preferred embodiment, in skipping the same over the surface of water by throwing the toy with a spinning motion and in a generally flat low trajectory. The disc, when made for skipping on water, is of a material having a density less than that water so that it will float. In the preferred mode, the device is in the form of a relatively small disc, preferably having at least one notch at the edge thereof, and formed on one side with an auger face oriented in one direction and on the other side with an auger face oriented in the opposite direction to enhance the motion of the disc and improve its skipping action especially on water. The auger faces provide a lifting motion to the disc and the different auger directions allow the disc to be spun from either hand.
