What is Killer Sudoku?
Killer Sudoku is a variant of the classic Sudoku puzzle that combines elements of Sudoku and Kakuro. Like regular Sudoku, you fill a 9×9 grid so that each row, column, and 3×3 box contains the digits 1–9. The twist: instead of pre-filled numbers, you get dotted cages with a target sum — the digits inside each cage must add up to that sum, and no digit can repeat within a cage. It adds a layer of arithmetic logic on top of the usual placement rules, making it a satisfying challenge.
