game involving five dice specially marked to simulate a playing-card deck's top six cards (ace, king, queen, jack, 10, 9). The object is to throw a winning poker hand, with hands ranking as in poker except that five of a kind is high and there are no flushes. After a player's first throw, he elects either to stand pat or to draw (throw again), as in draw poker; in the latter case he separates out his best-showing dice and rolls up to three of the dice again, after which his result stands. In a version called horses, a hand of five aces loses. The game of Yahtzee evolved from poker dice.
