A bowling bowl having a solid core surrounded by a solid spherical shell. The solid core, which is substantially spherical in configuration, further includes a top weight which is generally conical in configuration and two extending side wings which are generally alike in configuration but placed at different angles with respect to each other. The two side wings which extend outwardly from the solid core have a generally flat surface on one side of the extending wing. The described flat surfaces of each extending wing describe a plane generally perpendicular to each other. The combination of the top weight and two extending side wings give the bowling ball more even and constant revolutions at the time contact with the pins is made. Also, the combination keeps the high rolling track of a high roller off of the thumb and finger holes. Further, the combination also gives the ball an exceptionally positive trajectory, a very thorough impact, less deflection upon impact and a methodical penetration at impact.
