Kakuro Calculator

Simple calculator to find valid combinations of numbers for Kakuro puzzles

Kakuro Calculator is a simple to use calculator for those of you who do pencil and paper Kakuro puzzles.

Select the number of digits and the required sum, and the calculator will show you a list of all of the possible combinations of that many digits that can add up to that sum.

Already know some of the digits? Just tap the corresponding number buttons and the list will be reduced to only combinations that include those digits.

Do you have enough information to rule out some of the combinations? Tap on a combination that you know isn't valid (maybe it requires digits that have already been eliminated) and it will fade, making it easier to see potential patterns in the remaining solutions that you can exploit.

More combinations than will fit on the screen? The combination list scrolls with a simple touch-and-slide gesture to reveal the other combinations.

Find yourself jumping around between several sums in the same puzzle? Tap the "History" button and select from the list of recently used digit/sum combinations. If you use "history" to get back to a previously used combination, it will even remember which fixed digits had already been identified and which combinations had been excluded!
