Scoring and Ball Selection

How to Score

Game
A game consists of 10 frames. A maximum of two deliveries is made in each frame except in the 10th frame, when three deliveries are made if the player has scored a strike or a spare in that frame.

Strike
A strike is scored when all the pins are knocked down by the first ball rolled in a frame. It is marked with an X.  Because a strike earns 10 pins plus a bonus of all the pins knocked down by the next two balls, no figure is entered until the next two balls are rolled. A strike in the 10th frame earns two extra rolls.

Spare
A spare is scored when all pins are knocked down with two deliveries. It is marked with a /.  Because a spare earns 10 pins plus a bonus of all the pins knocked down by the next single ball, no score is entered until the first ball of the next frame is rolled.  A spare in the 10th frame earns one extra roll.

Open Frame
An open frame occurs when there are pins left standing after two balls. There is no penalty for an open frame, other than that of failing to gain the bonuses for a strike or a spare. When an open frame is made simply add those pins knocked down to the total in the previous frame.

Bowling Ball Selection

A good comfortable ball makes your game much more enjoyable and enables you to get the most out of the sport of tenpin bowling.

Weight
Select a weight which is comfortable for you.  Finding a weight that is not too heavy but also not too light is important for maximising your score.  

A weight and age guide to get you started -
Juniors 6 and under should use 6lb balls
Juniors 7 to 10 yrs olds should use 8-10lb balls
Juniors aged 11 to 14 years should use 9-12lb balls
Try a ball in the 10- to 14-pound range for a woman
Try a ball between 14 and 16 pounds for a man.

Be aware of any pain you experience during or after bowling. Excessive pain in your wrist or elbow can be a sign that the bowling ball is too heavy for you.  Shoulder pain can actually be a sign of both.  If your shoulder is hurting, it could be because you're overthrowing your bowling ball due to it being too light for you.
