  • Patent number: 4974858
    Abstract: A tossing game which may be utilized indoors or outdoors and which is similar to horseshoes includes the use of two boards which are positionable in spaced apart vertical alignment. Players stand behind a particular board and throw washers into holes located in the opposed board. In the preferred embodiment, three holes are positioned in each board and are given different score ratings. The two identical wood boards may be covered with a soft material, such as carpeting, to prevent the washers from bouncing when thrown. In a second embodiment, grooves are provided between the holes. The grooves permit washers to be tossed and rolled on their edges into a particular aperture.
