Abstract
A football-like game ball which is manually thrown through the air. The ball has a generally truncated ellipsoid outer contour with a Venturi-like nozzle passage extending coincident with a major axis of the ball. A plurality of weighted elements are located within or adjacent to an outer wall of the ball to provide rotational stability when the ball is thrown through the air and spun about the major axis.
