Game of skill, characterized by being constituted by a flat piece, endowed with a part in the form of a handle, which has, conveniently distributed several holes, whose part has fixed at its front end a rope that hangs a spherical piece of sufficient weight and diameter such that it can pass through all the said holes except one, located in the position closest to the handle, so that moving the piece properly it is possible to successively pass the ball through the holes until reaching the last, of smaller diameter, where it is retained.
