The following tables list the possible combinations for various sums for Killer Sudoku 9x9.
I have also bundled all the Killer Sudoku cage total tables in a handy reference guide "Killer Sudoku - Cage Total Tables".
The book lists the cage total tables for Killer Sudoku 6x6, 8x8, 9x9, 10x10 and 12x12.
