Killer Sudoku Rules
Killer Sudoku (Sumdoku)
Rules 1
Standard Sudoku rules apply: numbers 1-9 in every row, column, and 3x3 box.
Rules 2
Dotted cages have a target sum in the top-left corner. Digits in a cage must sum to that number.
Rules 3
No digit can be repeated within the same cage.
Pro Tip: The Rule of 45
Every row, column, and 3x3 box must sum to exactly 45 (1+2+...+9=45). Use this to calculate single outside cells!
