Goal

Bowling Rules

• The game consists of 10 frames.
  • In each frame the player has two rolls to knock down 10 pins.
  • The score for the frame is the total number of pins knocked down, plus bonuses for strikes and spares.
• A spare is when the player knocks down all 10 pins in two rolls.
  • The bonus for that frame is the number of pins knocked down by the next roll.
• A strike is when the player knocks down all 10 pins on his first roll.
  • The frame is then completed with a single roll.
  • The bonus for that frame is the value of the next two rolls.
• In the tenth frame a player who rolls a spare or strike is allowed to roll the extra balls to complete the frame.
  • However no more than three balls can be rolled in tenth frame.

Implementation

Write a class Game that has two methods:

• roll(int $pins): void is called each time the player rolls a ball. The argument is the number of pins knocked down.
• score(): int returns the total score for that game.
