- Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box.
- Unique Killer Cages: Within a cage, digits don't repeat and they must sum to the small number written in the top left of that cage. Additionally no digit may be used more than once among all the cages of the same sum, even if that sum is not explicitly given.
