+| 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.

+# Introduction
+
+Each year, something new is "all the rage" in your high school.
+This year it is a dice game: [Yacht][yacht].
+
+The game of Yacht is from the same family as Poker Dice, Generala and particularly Yahtzee, of which it is a precursor.
+The game consists of twelve rounds.
+In each, five dice are rolled and the player chooses one of twelve categories.
+The chosen category is then used to score the throw of the dice.
