Game of skill composed of two small balls, one with circumferential channels, and the other with a circumferential protuberance, which engages the said channels; the player makes the first ball rotate by means of projections, and must keep the second ball in equilibrium, which rotates in a direction contrary to the first, and moves along the channels.
A recirculatory ball spindle with semi-spherical supports and undulating- spheroidal movement for the self-alignment of the openings to the grooves in the nut-deflector set.
