A puzzle of the type including three tracks arranged on a sphere in radial planes mutually at right angles and elements movable along the tracks includes the elements in the form of balls rollable along cylindricaltracks with an open area of the track surface available to grasp the balls and rotate them within the track in a row. The body is molded as an integral element with an open area inside the track thus using minimum materials and allowing the product to be molded in one piece. The balls are locked in place to prevent misalignment by a sprung retaining member which engages into the cusp between two balls in one of the tracks. The balls are arranged with different colors associated with different parts of the tracks and including a separate color for the balls at the six intersection points.
