Yacht

Yacht is a public-domain five-dice scoring game first described in Hoyle's Rules of Games in 1938 — a direct predecessor of Yahtzee. Each turn a player rolls five dice up to three times, then scores in one of 12 unused categories (Ones through Sixes, Full House, Four of a Kind, Little Straight 1-2-3-4-5, Big Straight 2-3-4-5-6, Choice and Yacht). Yacht = five of a kind, worth 50 points.
