THREE-DIMENSIONAL CUBICAL PLAYING APPARATUS Russian patent published in 1997 - IPC

FIELD: puzzle-type playing device. SUBSTANCE: apparatus has axial, rib and angular playing members mounted on support for layer-by-layer turning about their three axes and provided with slots and ridges, which may be conjugated one with the other and with support to form six faces, nine members in each face. Each axial playing member has one, rib member- two and angular member - three numerical nondetachable fields, which may not be offset one with respect to the other. Set of eight numbers of a,b,c,d,e,f,g and n with relation of a <b <c <d <e <f <g <n, are applied to each face of cube. The number of a is at least 0 and the remaining are actual whole numbers. Numerical fields of angular playing members are provided with triades and numerical fields of rib members are provided with pairs of different numbers. Each number is presented three times on numerical fields of angular and rib members of cube face. Numerical fields of axial members are numbered with figures from 1 to 6 so that total sum of numbers-figures of opposed faces is constantly equal to 7: 1:6, 2:5; 3:4. EFFECT: increased entertaining effect and simplified construction. 4 dwg
