Bowling Match Problem
A bowling match consists of ten frames.
- Each frame except for the tenth consists of one or two balls, or attempts to knock down the ten pins at the end of the alley.
- Doing so on the first ball of the frame is called a strike, and the second ball of the frame is not rolled.
- Knocking down all ten pins with both balls (having left some up with the first ball) is called a spare.
- If both attempts to knock down the pins leave some standing, the frame is called an open frame.
- A spare in the tenth frame gives the bowler one extra ball. A strike in the tenth gives him or her two extra balls.
A bowling score is computed as follows.
- A strike counts as 10 points plus the sum of the next two balls.
- A spare counts as 10 points plus the next ball.
- Any other balls merely count as themselves, as do any bonus balls rolled as a result of a strike or a spare in the tenth frame.
