The classic shake and score dice game! Yahtzee is a dice game almost entirely governed by chance. Common sense helps determine which dice to keep and which to re-roll. Assuming all players use common sense and the dice are fair; the outcome of the game is random. In the game, a yahtzee is statistically the most difficult roll to obtain as it is comprised of five dice all showing the same face. The probability of obtaining a yahtzee in a single roll is 0.1 percent; and the probability of obtaining a yahtzee in three rolls is 4.6 percent. Don't worry; though - there are thirteen different categories to score. All the players have to do is roll any dice up to three times; to achieve the highest scoring combination possible. This game is suitable for any number of players - even one. Yahtzee was invented by a Canadian couple almost fifty years ago who wanted an easy fun game that could be played aboard their yacht. Yahtzee is easy to understand but it needs to be played to be really appreciated. So pick up our Yahtzee set - specially designed to hold the slightly-larger Braille dice - and throw a Yahtzee party of your own. Includes one wooden cup and five tactile wooden dice.
