Abstract

Abstract A ball game has a housing with a transparent cover, and a labyrinthine platform disposed in the housing. A plurality of balls are positioned between the platform and the transparent cover. The labyrinthine platform is resiliently loaded in the direction towards the transparent cover, and thus tends to trap the balls between the platform and the cover. One or more actuating handles are provided to project externally of the housing for shifting the labyrinthine platform against the action of its loading, thereby to free the balls, thus giving the user a possibility of controlling the running of the balls on the labyrinthine platform.
