Kata Farkle

In the following kata we will play a variation of the classical Farkle Dice Game.

In this version I put together a simplified set of rules, just to practicing Object Calisthenics.

Here and here the slides I made for a couple of workshop I facilitated at TDD Milano and Agile Venture Prato.

Rules

2 players, in turn, roll 6 dice
The score is calculated according to the standard rules represented in the image below
If your score is 500+ points, you are entitled to make another throw
The first one that reaches (or overcomes) 10.000 points, wins

3 of a kind = triplet
4 of a kind = quatern
5 of a kind = five

The 1 and 5 are the only dice that score even if the amount is less than 3
Three dice of one type give points equal to their value multiplicated by 100 (e.g. a triplet of dice 2 gives 200 points), except for one type: a triplet of 1 gives 1000 points
The quaternes doubles the triplet points (e.g. a quatern of dice 2 gives 400 points)
The five triples the triplet points (e.g. a five of 2 gives 600)

These are the standard scores for single dice or combinations of dice:

Here a more compact view:

5	6	1	2	2	5	Total Score
50	+0	+100	+0	+0	+50	200 points

6	6	6	6	5	5	Total Score
0	+0	+6x100	+6x100	+50	+50	1300 points

2	2	6	6	4	4	Total Score
0	+0	+0	+0	+0	+0	0 points
