“ In the score, the strike counts ten for the player and in addition also whatever he gets on the next two balls. Likewise he will count ten for a spare, but only what he gets on one ball for a bonus. As a consequence the maximum or perfect score in bowling is 300, which is a series of ten strikes and two more attempts in which he knocks down all the pins. In lawn bowling the scores are very low as compared with the indoor game, where good players will often average close to 200 on alleys where they are accustomed to bowl. ”
