Yahtzee

To begin their turn, a player rolls five dice. They are then allowed to take up to two rerolls, each reroll being of any number of those dice.

After those rerolls, or when the player chooses to stop rerolling, 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.

The scoring categories for Yahtzee are 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.

For example, a roll of 1-1-2-5-5 could be scored as 2 points in the "ones" category, 2 points in the "twos" category, 10 points in the "fives" category, or 0 points in the "threes," "fours," or "sixes."

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.

Lower section

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 1-2-3-4, 2-3-4-5, or 3-4-5-6) -- 30 points

Large Straight: Five dice having sequential numbers (1-2-3-4-5 or 2-3-4-5-6) -- 40 points

Yahtzee: All five dice showing the same face -- 50 points. You get 100 bonus points for 2 yahtzees

Chance: Any combination -- points equal the sum of all 5 dice

Yams

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

Upper section

This is similar to Yahtzee but the bonus is calculated differently. The bonus threshold is 60 points, and is 30 points + the difference between the score achieved and 60.

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.

Lower section

Scoring is different here for three and four of a kind. A yams (Yahtzee) also scores differently. The least obvious difference is the Rigole category in the last category. This category is for four matching dice and one which has the inverse pip configuration on it. So 4-4-4-4-3 or 1-1-1-1-6
