Abstract
Apparatus for randomly selecting numbers from a predetermined set consisting of two elongated dies, each in the form of a heptagonal right prism. Each face of the first elongated die is colored with a color different from the color of all of the other faces. Each elongated face of the second die is subdivided into seven segments, each segment being colored with the color of one of the faces of the first die. Each segment of the second die bears a representation of one of the decimal numbers from 1 to 49, inclusive.
Claims3
Apparatus for randomly selecting numbers from a predetermined set, comprising:
- a first elongated die having a plurality of elongated faces which are symmetrically disposed about a common axis, each of said faces being of a color different from the color of all of the other faces;
- and
- a second elongated die having a plurality of elongated faces which are symmetrically disposed about a common axis, the number of faces of said second die being equal to the number of faces of said first die, each face of said second die being divided into a number of segments equal to the number of faces of said first die, one segment of each face of said second die being colored to match one of the faces of said first die, and each segment of said second die bearing a representation of one number of said set which is not represented on any other one of said segments.
