Yahtzee

A player rolls five dice to begin a turn. They are then allowed to take up to two rerolls, each reroll being any number of those dice. (In BGA, you click on the dice that you want to reroll.)

After those rerolls, or when the player chooses to stop rolling, the player must choose which category to score the final result. There are 13 scoring categories, and each must be used for one of the 14 rounds. This can often force a player to take a zero score for some categories.

Scoring for Yahtzee is as follows

Upper section

1-6: One category for each number on the die. In these categories, the score is the sum of the pips on the dice of that number.

If a player scores a total of at least 63 points across these six boxes combined, a bonus of 35 points is added to their final score. (Tip: Scoring Three of each number is exactly 63 and nets the bonus.)

Lower section

Roll	Requirement	Example	Score
Three-Of-A-Kind	At least three dice showing the same face	​​​​​	Points equal the sum of all 5 dice (not just the 3 of a kind)
Four-Of-A-Kind	At least four dice showing the same face	​​​​​	Points equal the sum of all 5 dice (not just the 4 of a kind)
Full House	A three-of-a-kind and a pair	​​​​​	25 points
Small Straight	Four dice having sequential numbers	​​​​​	30 points
Large Straight	Five dice having sequential numbers	​​​​​	40 points
Yahtzee*	All five dice showing the same face	​​​​​	50 points
Chance	Any combination	​​​​​	Points equal the sum of all 5 dice

* If you get a 2nd yahtzee, you automatically get 100 bonus points. You must score it in the appropriate upper section if it is available. Otherwise, you can use it as a "joker" to score another category in the bottom section.

Yams

In the game of Yams, the categories and calculations are slightly different. Scores are generally higher.

Upper section

This is similar to Yahtzee but the bonus is calculated differently. The bonus threshold is 60 points, and the bonus is the difference between the score achieved and 30. For example: When you complete your upper with 63, you would score 63 - 30 = 33 bonus points.

Middle section

This is a higher and lower section which are similar to Chance in Yahtzee and a bonus that is the difference between them.

• Plus - scores the sum of all dice
• Minus - scores the sum of all dice
• Delta - automatically calculated - scores the Plus score minus the Minus score

So if the Plus score was 22 and the Minus score was 13, the Delta score would be nine. Note that Plus and Minus does not count towards the final score.

Lower section

Scoring is different here for four of a kind and there is no three of a kind. There is no chance. Yams is more generous: four 1s will net you 40+ points in four of a kind, whereas in Yahtzee it would net you a maximum of 10 points.

• Four of a Kind - 40 points plus the sum of the dice
• Full House - 30 points plus the sum of all dice
• Small Straight - 45 points
• Large Straight - 50 points
• Yahtzee (Yams) - 50 points plus sum of dice
• Rigole - 4 times the same number and 1 time the opposite number on a dice. This gives six possible sequences:
