The object of Yahtzee is to obtain the highest score by throwing five dice in 13 rounds to achieve the combinations on the score card. A player may roll the dice up to three times in each turn. Five-of-a-kind is considered a Yahtzee and scores 50 points.
Each player gets a score card with 13 categories. The upper section of the score card contains the numbers one through six, and the object is to get as many of one kind in a single round as possible. For example, if a player gets two sixes in the first round, he can set those aside, and roll the rest of the dice two more times to get more sixes. The player's score is equal to the number on the die times the number of times it was rolled. For example, if a person rolled three fives, his score is 15.
The lower section contains combinations a player attempts to roll the dice for. Combinations include four-of-a-kind, full house, which is three-of-a-kind and a pair, and a large straight, which is one through five on the dice. A player can only fill in one category in each turn, so he must decide during or after each round which category he is going for. A player cannot score in a category twice. At the end of the game, the player with the most points wins.
