Make bowling readme less object-oriented specific.

[pminten]

Please note that I don't think I've ever played a game of bowling in my life, so it could be I broke the description of the rules.

This looks correct to me (although I believe I've only played bowling once, and only because they guilted me into participating).

When I was younger I bowled in a league.

A frame is composed of one or two ball throws with ten pins standing at frame initialization. There are three cases for the tabulation of a frame.

• An open frame is where a score of less than 10 is recorded for the frame. In this case the score for the frame is the number of pins knocked down.
• A spare is where all ten pins are knocked down after the second throw. The total value of a spare is 10 plus the number of pins knocked down in their next throw.
• A strike is where all ten pins are knocked down after the first throw. The total value of a strike is 10 plus the number of pins knocked down in their next two throws. If a strike is immediately followed by a second strike, then we can not total the value of first strike until they throw the ball one more time.

Here is a three frame example:

Frame 1	Frame 2	Frame 3
X (strike)	5/ (spare)	9 0 (open frame)

Frame 1 is (10 + 5 + 5) = 20
Frame 2 is (5 + 5 + 9) = 19
Frame 3 is (9 + 0) = 9

This means the current running total is 48.

The tenth frame in the game is a special case. If someone throws a strike or a spare then they get a fill ball. Fill balls exist to calculate the total of the 10th frame. Scoring a strike or spare on the fill ball does not give the player more fill balls. The total value of the 10th frame is the total number of pins knocked down.

Assume a tenth frame of:
X1/

Here the total value of the 10th frame is 20.

Assume a tenth frame of:
XXX

Here the total value of the 10th frame is 30.

I think the readme still isn't clear enough for special case of the tenth frame. Let me know if you like this explanation and I'll submit a pull request.

Thanks. Would you mind if we use your explanation I in the readme? It's clearer than what it currently says.

Considering the not too low not too high complexity of the notation it may actually make a good theme for a second exercise: parse a bowling scoreboard and determine if it's valid.

• An open frame is where a score of less than 10 is recorded for the
  frame. In this case the score for the individual frame is the number of
  pins knocked down.
• A spare is where all ten pens are knocked down after the second throw
  is called a spare. The total value of a spare is 10 plus the value of
  their next immediate throw.
• A strike is where all ten pens are knowcked down after the firt
  throw. The total value of a strike is 10 plus the value of their next
  two immediate throws.

Here is a three frame example:
1 2 3
X 5/ 90

Frame 1 is (10 + 5 + 5) = 20
Frame 2 is (5 + 5 + 9) = 19
Frame 3 is (9 + 0) = 9

This means the current running total is 48.
