A full house in Yahtzee is composed of three of any number plus two of any other number, according to HowStuffWorks. This combination of dice scores 25 points.
Yahtzee rules do not specify which numbers must make up the full house, as long as there are three dice showing one number and two showing the other number. Unlike other scoring combinations of dice in Yahtzee, the full house does not depend on the value of the numbers showing on the dice. According to the mathematics department of Cornell University, this fact can affect the best strategy when a player rolls a full house.
