A golf ball having a circular dimples and uncircular dimples arranged in a different percentages depending on spherical zones, whereby a favorable aerodynamic property is obtained by eliminating the difference in trajectories between line hitting and face hitting. In a spherical zone in the vicinity of the great circle uncircular dimples are arranged in a percentage higher than circular dimples, whilst in a spherical zone further from the great circle circular dimples are arranged in a higher percentage. <IMAGE> |
