Killer Sudoku Combination Calculator
A Killer Sudoku cage tells you the total sum for a group of cells. This calculator helps you list possible digit combinations for that cage, so you can solve faster without repeatedly doing arithmetic by hand.
How to Use the Calculator
- Enter the cage sum, such as 17.
- Enter the number of cells in the cage, such as 3.
- Remove any digits that are already impossible or already used.
- Copy the remaining combinations into your solving notes.
Example
For a 3-cell cage with a sum of 17 and no repeated digits, possible combinations include 1 + 7 + 9, 2 + 6 + 9, 2 + 7 + 8, 3 + 5 + 9, 3 + 6 + 8, 4 + 5 + 8, and 4 + 6 + 7.
