In early times golfers made out that irregularities in the surface of the ball would let the ball fly higher and farer. Soon, right after the Gutta Percha balls the so called dimples were purposely printed into the surface of each ball. Still nowadays, most of the ball manufacturers are testing out different shapes and numbers of dimples. The rule goes: the more dimples a ball has, the higher it goes. Then, balls having too many dimples, do fly too high and are lacking distance. Most companies have found their best number of dimples, mostly they are ranking between 300-500 per ball.
