Killer Sudoku Helper Tool

Jump straight to the calculator

Killer sudoku is a puzzle that combines sudoku and kakuro.

Unlike regular sudoko, these puzzles introduce an element of arithmetic. For simple puzzles this can actually make solving easier, but a difficult killer sudoku may easily take many hours.

The standard sudoku rules apply, but in addition the sum of all numbers in a 'cage' must match the small number in the corner of the cage.

No number may appear more than once in a given cage

Our tool does not solve killer sudoku puzzles - rather it is intended to help you in your own solving, by identifying valid combinations as you go.

Use the Combinations page for the main tool, or the Specials page to find instances of cage size and target number for which there is only valid combination.
