Claim:
A golf ball comprising: a ball center and a spherical surface having a pair of poles and an equator, and a plurality of dimples on the spherical surface, wherein at least some of the plurality of dimples are arranged within spherical isosceles triangle regions which are formed by drawing a plurality of imaginary lines equally spaced from each other connected from one pole to the equator on one hemisphere divided by the equator, wherein the dimples arranged adjoining along one imaginary line of the plurality of imaginary lines are located such that those dimples arranged on an area relatively close to the pole are arranged with substantially zero or very short distance to the imaginary line and those dimples on an area closer to the equator are arranged with a longer distance to the imaginary line, and the dimples on the other hemisphere divided by the equator are in point symmetry with the dimples on the one hemisphere with respect to the ball center.
