Bowling points rules:

保龄球一局由10轮组成。球员前9轮中，除了打出全中球外，每轮都有两次投球机会。第10轮全中时再奖励两次投球机会，奖励球的得分应累计在该局的总分内。如果第10轮为补中，则再奖励一次投球机会，所得分同样累计在该局的总分内。如果从第1轮的第一个球到第10轮的两个奖励全部是一次击倒球瓶的话，即为满分300分。

保龄球成绩记录在记分格上。每局球记分格上共有10格，第1格到第9格各有两个小栏。第10格则有三个小栏。第一栏记录的是第一次击倒的球瓶数，或是记载“全中”的符号即［×］。第二栏记录的是第二次击倒的球瓶数或“补中”的符号即［／］。第10格的第三栏只有在第10轮投球“全中”或“补中”时才用得上。特别注意的是记分栏记录的是每轮得分的累计分，而不是每轮的得分。每一格投球可能出现三种情况：

补中。每轮的第一次掷球未能将全部球瓶击倒，第二次掷球将剩余的球瓶全部击倒，称为“补中”。此轮的得分是10分加上下一次掷球击倒的瓶数。如果该轮第一次掷球未得分，第二次掷球将所有球瓶击倒，也算作为补中。

失球。无论何种情况，在一格的两次投球时，未能击倒所有10个瓶，此轮的分数为击倒的瓶数。在每轮第一击球时可能会出现分瓶，即第一次投球击倒部分球瓶（①号球瓶必须被击倒），余下的两个或两个以上球瓶成分开的形状。出现分瓶多数情况会导致失球。

全中。每轮的第一次掷球将全部球瓶击倒，称为“全中”。这一轮就此结束，不再进行第二次掷球。此轮的得分是10分加下两次投球击倒的瓶数。

第十格的记分情况比较特殊：

如果第一球为全中，则追加两次投球机会，第十格得分为10分加上追加两次投球击倒的瓶数。如果第二次投球未补中，则第十格得分为第十格所击倒的瓶数。如果第二次投球补中，则追加一次投球机会，第十格得分为10分加上追加一次投球击倒的瓶数。
