Santa brought my kids the game of Yahtzee for Christmas. We’ve been playing it a lot in the evenings. When a Yahtzee is rolled, my kids go wild. In this blog posting I'm going to look into the probability of rolling a Yahtzee. Yahtzee is a game played with five six-sided dice. A player rolls the dice, examines the results and can keep as many of the dice as they like, re-rolling the remainder. After the second roll, the process is repeated (if desired, the player can pick-up dice held on the first round). After (up-to) three rolls, the dice are scored according to various categories. The Yahtzee (scoring 50 points) is achieved by getting all five dice the same.
