+# Instructions
+
+The dice game [Yacht][yacht] is from the same family as Poker Dice, Generala and particularly Yahtzee, of which it is a precursor.
+In the game, five dice are rolled and the result can be entered in any of twelve categories.
+The score of a throw of the dice depends on category chosen.
+
+## Scores in Yacht
+
+| Category | Score | Description | Example |
+| -------- | ----- | ----------- | ------- |
+| Ones | 1 × number of ones | Any combination | 1 1 1 4 5 scores 3 |
+| Twos | 2 × number of twos | Any combination | 2 2 3 4 5 scores 4 |
+| Threes | 3 × number of threes | Any combination | 3 3 3 3 3 scores 15 |
+| Fours | 4 × number of fours | Any combination | 1 2 3 3 5 scores 0 |
+| Fives | 5 × number of fives| Any combination | 5 1 5 2 5 scores 15 |
+| Sixes | 6 × number of sixes | Any combination | 2 3 4 5 6 scores 6 |
+| Full House | Total of the dice | Three of one number and two of another | 3 3 3 5 5 scores 19 |
+| Four of a Kind | Total of the four dice | At least four dice showing the same face | 4 4 4 4 6 scores 16 |
+| Little Straight |  30 points | 1-2-3-4-5 | 1 2 3 4 5 scores 30 |
+| Big Straight | 30 points | 2-3-4-5-6 | 2 3 4 5 6 scores 30 |
+| Choice | Sum of the dice | Any combination | 2 3 3 4 6 scores 18 |
+| Yacht | 50 points | All five dice showing the same face | 4 4 4 4 4 scores 50 |
+
+If the dice do not satisfy the requirements of a category, the score is zero.
+If, for example, *Four Of A Kind* is entered in the *Yacht* category, zero points are scored.
+A *Yacht* scores zero if entered in the *Full House* category.
+
+## Task
+
+Given a list of values for five dice and a category, your solution should return the score of the dice for that category.
+If the dice do not satisfy the requirements of the category your solution should return 0.
+You can assume that five values will always be presented, and the value of each will be between one and six inclusively.
+You should not assume that the dice are ordered.
