HowStuffWorks says that a full house in Yahtzee is three of any number plus two of any other number. This roll of the dice is worth 25 points.
The rules of Yahtzee don’t say which numbers must be on the full house. As long as three dice show one number and two show the other number, the full house is made. In Yahtzee, the full house is different from other ways to score because it doesn’t depend on the numbers on the dice. Cornell University’s math department says that this can change what the best move is when a player gets a full house.
