Roll the dice with Dr. Dice in this free online game similar to Yahtzee! Roll up to 3 times in each turn, going for different dice combinations such as all 1s, 2s, 3s, 4s, 5s, 6s, 3 of a kind, 4 of a kind, small straight (4 consecutive dice), large straight (5 consecutive dice) and Five Dice, which is 5 of a kind or a Yahtzee. Earning points will fill the meter on the left. Passing certain marks will open power ups. Using a power up lowers the meter. The first power up is a 1-dice re-roll. The 2nd power up is re-roll of all selected dice. The 3rd allows a change of the value of any one dice to another value.
