Introduction

The object of the game is to score the most points by rolling five dice to make certain combinations. The dice can be rolled up to three times in a turn to try to make one of the thirteen possible scoring combinations. A game of Yahtzee consists of thirteen rounds during which the player chooses which scoring combination is to be used in that round. Once a combination has been used in the game, it cannot be used again. Each of the scoring combinations has a different point value, some of which are fixed values and others of which have the cumulative value of the dice. A Yahtzee is a five-of-a-kind and holds the game's highest point value of 50.

Overview

The Yahtzee scorecard contains thirteen boxes divided between two sections: The Upper Section and The Lower Section

Upper Section

In the upper section, each box is scored by summing the total number of dice faces matching that box. For example if a player were to roll three "twos", the score would be recorded as 6 in the twos box. If a player obtains or exceeds 63 points, a bonus of 35 points is added to the upper section score. Though 63 points corresponds to three-of-a-kind for each of the six die faces, a common way to get the bonus is rolling four (or five) of a larger number so that less of the lower ones are needed.

Lower Section

The lower section contains a number of poker-themed combinations with specific point values:

• Three-of-a-Kind (sum all dice)
• Four-of-a-Kind (sum all dice)
• Full House 25pts
• Small straight 30pts
• Large straight 40pts
• Five-of-a-Kind (Yahtzee) 50pts
• Chance (sum all dice)

Chance often acts as discard box for a turn that will not fit in another category (thus the name), although during a lucky game it can be used to record a high score.

Game Play

On each turn, a player gets up to three rolls of the dice. He or she can save any dice that are wanted to complete a combination and then re-roll the other dice. After the third roll, the player must find a place to put the score (though he or she can choose to end the turn and score after one or two rolls if desired). If the resulting combination of dice will not fit in any unused scoring category, the player must place a "zero" in one of the unused boxes. Each player's total score is calculated by summing all thirteen score boxes.

Yahtzees and bonus chips

A Yahtzee occurs when all five dice have the same value during a player's turn. Yahtzee is the most difficult combination to throw in a game and has the high score of 50 points. If a player scores one or more additional yahtzees during the same game, that player is awarded bonus points and given bonus chips that correspond to each additional Yahtzee that a player rolls. Bonus yahtzees are worth 100 points each. Bonus chips are only awarded for subsequent Yahtzees if the first Yahtzee was placed in the 50pt Yahtzee score box. Additional Yahtzees may be used as wild cards in the lower section provided that the corresponding upper section box has been filled. For example, if a player rolled out five threes (a Yahtzee in the threes), the player could only use it as a wild card in the lower section if he or she already had a score in the "threes" box in the upper section. If the "threes" box was still open, the player must score 15 in the threes (sum of five threes).
