1. An amusement device comprising:

  • a body member having a substantially spherical shape with six equally-sized indentations formed thereon;

    each of said indentations comprising an annular rim, tapered side walls extending inwardly from said annular rim and a flat circular surface positioned radially inwardly from said annular rim,said body member having a spherical surface between said annular rims;

    a plurality of raised indicia being on said flat circular surfaces, said raised indicia having a height less than the distance between said rims and said flat circular surfaces whereby said rims prevent said indicia from interfering with rolling of said body member on a flat surface;

    a dimple formed in said spherical surface, said dimple being concave and being substantially smaller than said indentations so that the statistical chances of said body coming to rest on said dimple are smaller than the chances of coming to rest on one of said indentations.
