Bowling Kata v2

Inspired by

• The Bowling Game Kata
• 99 Bottles  

Part One

Produce a solution to the bowling game kata using your favorite methods.

Part Two

Changes in bowling alley technology are entering the market; the new hardware offers cheaper, efficient, environmentally friendly bowling.

But there's a catch... the sensors on the new bowling alleys don't detect the number of pins knocked down by each roll, but instead the number that remain upright.

Without making any changes to the existing tests: create an implementation that correctly scores the games reported by the new bowling alleys.

Examples

A perfect game still consists of twelve throws, but when the ball knocks down all of the pins, the sensors report 0 rather than 10.

Similarly, a "gutter game" has twenty throws, and the sensors report 10 for each throw.

A spare where 9 pins are first knocked down, and then 1, is reported as (1,0).

Part Three

The advanced bonus round

Repeat the exercise described in Part Two, starting from an implementation of the bowling game kata that is _unfamiliar_ to you.

Update

I found Tim Riemer's github repository, and forked a copy to use as the seed for part three.  The results are available on github: https://github.com/DanilSuits/BowlingGameKataJUnit5
