Challenge

Build a ScoreCard object for keeping track of bowling scores.

Rules

• A game consists of 10 frames.
• In each frame the player has two opportunities to knock down 10 pins.
• The score for the frame is the total number of pins knocked down, plus bonuses for strikes and spares.

Spares

• A spare is when the player knocks down all 10 pins in two tries.
• The bonus for that frame is the number of pins knocked down by the next roll.
• If a spare is bowled in frame 3, and the first roll of frame 4 is a 5, the score for frame 3 is 10 plus a bonus of 5.

Strikes

• A strike is when all 10 pins are knocked down on the first roll of a frame.
• The bonus for that frame is the value of the next two balls rolled.
• If a strike is bowled in frame 3, and the scores for frame 4 are 1 and 5, the score for frame 3 is 10 plus a bonus of 6 (5 + 1).

10th Frame

• In the 10th 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 the 10th frame.
• A perfect game is therefore 12 strikes, yielding a score of 300.
