Below we explain the rules for each game below and explain the probabilities of rolling certain combinations. You can also try your luck with the poker dice/Yahtzee game above.

Poker Dice Rules

In traditional poker dice, each player has three opportunities to roll five dice. After the first roll, you may hold some dice and roll the remaining dice. After the second roll, you may hold more dice or release previously held dice before rolling for the last time. After the third roll, the dice are examined. There are eight possible outcomes shown in the table below. The right column shows the probability of attaining each outcome in a single throw of the dice.

Note that even though a straight is harder to roll than a full house, full house outranks straight. Also note that the probability of having nothing but a high card is quite low, only 6%.
