What is Killer Sudoku

Killer Sudoku is a true legend of all number games and puzzles. In a nutshell, it’s a perfect blend of a free sudoku puzzle game and a kakuro game.

This number puzzle bears many names: sumdoku, addoku, cross-sum, etc, but the rules are equally simple across the board. Your goal is to fill the grid with numbers like in classic sudoku and also make sure the sum of numbers in cages (areas separated by dotted lines) is equal to the number in the upper left corner of that cage. Still, sounds complicated? Let’s review Killer Sudoku rules in detail below.

How to play Killer Sudoku

✓ Fill all rows, columns, and 3×3 blocks with numbers 1-9 exactly like in sudoku classic
✓ Pay attention to the cages – groups of cells indicated by dotted lines.
✓ Make sure the sum of numbers in each cage is equal to the number in the upper left corner of the cage.
✓ The specific rule of the Killer Sudoku puzzle is that the sum of all numbers of each 3×3 block, row, or column always equals 45.
✓ Numbers cannot repeat within cages, a single row, column, or 3×3 region.
