  • Patent number: 5890716
    Abstract: A dice-like toy composed of a polygonal body with main surfaces located in pairs opposite each other, which are respectively used as resting surfaces and as display surfaces. The main surfaces are arranged on the body in such a way that the axis of symmetry of oppositely located resting and display surfaces are inclined relative to each other. This results in a shape of the toy which, in contrast to conventional dice, no longer generates an essentially straight-line throw, but causes more direct and more abrupt directional changes in the course of progress because of increasingly occurring edges. In this connection, elliptical surfaces are particularly preferred as the main game surfaces, wherein the two elliptical main axes of oppositely located main surfaces extend perpendicularly to each other.
