Golf ball

The golf ball of claim 5, wherein the contour at the top edge position of the non-circular dimples includes concave curved portions and convex curved portions as viewed from an inside of the non-circular dimples.

The golf ball of claim 5, wherein the contour at the top edge position of the non-circular dimples is formed by a combination of curved lines and straight lines.

The golf ball of claim 5, wherein the total number of circular dimples and non-circular dimples is from 250 to 550.

A golf ball comprising a spherical surface having a plurality of plan view circular dimples and plan view non-circular dimples, wherein the non-circular dimples have at a top edge position a contour length of at least 20 mm and account for at most 10% of all the dimples, wherein the non-circular dimples have a bottom portion which is formed in the shape of an arc that projects radially outward on the ball.

A golf ball comprising a spherical surface having a plurality of plan view circular dimples and plan view non-circular dimples, wherein the non-circular dimples have at a top edge position a contour length of at least 20 mm and account for at most 10% of all the dimples, wherein the non-circular dimples have a recessed volume, summed for all the non-circular dimples on the ball, which is at most 0.5% of the volume of the ball were the spherical surface to be free of dimples.
