Quickly calculate six-sided dice probabilities.

For a given sum and selected number of dice, the following probabilities are displayed: equality, greater than, less than, greater than or equal, less than or equal.

For combinations, the probability of a specific dice combination (ex: 3 ones, 2 fours) is displayed along with the probability for the same combination with any dice (ex: any full house).

Lastly, you can calculate probabilities for getting "at least" some number of dice. For example, the probability of getting at least two sixes using five dice.

The iPad version displays a bar graph of the relative probabilities.

Save your dollar for something that actually works!

Not only does it crash when you put it on 6 dice but it really doesn't work otherwise... There is no button to push that allows you to calculate once you have input the info... Worthless crap that takes up space on your phone while it robs you for a buck! POS!

By far the best on the App Store.

So much better than expected, when you roll the number "wheels" the answers are constantly changing whatever it stops on all the fields display the correct answer. Even though there is a glitch in one of the 3 different features of the app. It's easily figured out if needed. I'm going to contact the dev. 5 stars because I don't know of any App Store App that does what this does better.


Garbage! Do not buy!

Does not work. You can't change any factors. POS
