The present invention relates to a new and inventive combination game combining aspects of ball and/or bowling games, The invention further relates to a game set comprising all elements necessary to perform the game and to a method of playing a combined game.

A surface of a sphere is divided by using not only great circles but also small circles, forming a spherical polyhedron. The spherical polyhedron includes two spherical regular pentagons, each having a center at the pole, ten spherical isosceles triangles near the pole, ten spherical pentagons near the equator, and ten other spherical isosceles triangles near the equator. Compared to a related art, dimples are accurately arranged in spherical polygons. Thus, a dimple area ratio is improved and the number of dimples is appropriately maintained.

A lightweight spherical baseball like training ball has a hollow polyethylene plastic core adhered to a stitched white colored synthetic leather cover with a thin layer of adhesive. The lightweight ball has raised seams and measures in circumference similar to the ball circumference size mandated by Major League Baseball or softball rules whereby the ball is suitable for baseball and softball training and playing variations of the game of baseball or softball in confined areas.

The present invention provides golf balls having a pattern of stellated polygon shaped dimples and grooves with pre-selected and coordinated color appearances on the outer surface of the ball to produce a unique and desirable overall golf ball color appearance.

A flight-enhanced ball has an exterior liner, a series of texturizing recesses, and a ball body. The exterior liner is superimposed onto the ball body and used to provide a textured or friction-reducing surface. Additionally, the texturizing recesses traverse into the exterior liner to provide a textured surface that facilitate throwing the ball in a straight line at high velocities. The ball body is designed to be semi-deformable to act as a shock absorber. Thus, the ball body enables the ball to absorb the impact forces generated by a collision with an athletes' body.

An impact-absorbing ball has an exterior liner, a ball body, and a damper core. The exterior liner is superimposed onto the ball body and used to provide a textured or friction-reducing surface. The damper core is integrated into the ball body and has multiple density-modified regions that are used to modify the overall durometer of the ball. Thus, the damper core enables the ball to absorb the impact forces generated by a collision with an athletes' body.

This invention provides sports ball having asymmetrical traction and/or asymmetrical surface structure. The asymmetrical traction is useful for differentially controlling ball spin and trajectory height as the ball is projected from a pitching machine. The asymmetrical surface structure is useful for differentially controlling the lateral component of the ball's trajectory. Optionally, the ball is a pitching machine ball. The method also provides a method of projecting the ball from a pitching machine.

To provide a golf ball that can prevent a decrease in carry distance of a driver shot when it rains and also, can exert excellent spinning performance upon an approach shot. The golf ball of the present invention includes a core, a cover that is provided on an outer side of the core and is provided with dimples, and an outermost layer that is formed on an outer side of the cover and made of a material having a contact angle of 90 or more. The golf ball has a dynamic friction coefficient of 0.52 or more. The material constituting the outermost layer comprises a urethane coating that contains a water repellent additive, and the water repellent additive includes a fluorinated surfactant, silicone-modified acrylate or hydrophobic silica.
