Abstract
An amusement device composed of a transparent hollow sphere and rotatable transparent discs dividing it into two hemispheres. Each hemisphere is further divided into four compartments by transluscent wall segments moveable upon the discs. A rotatable handle is further attached to the apex of the segments from outside the sphere which is able to rotate the compartments. Each disc has a round opening to permit passage of a marble and another opening to permit passage of dice and rotates freely being activated by the dice being trapped between its opening and the moveable compartment wall. The object of the invention is to tilt the sphere and align the openings in the discs by means of the dice so as to permit one to have single colored marble in a number of pre-identified compartments and dice in the pre-identified compartment after sorting the dice and marbles. Any number of marbles and dice can be in the groups as long as the groups are equal.
