I always find it gratifying when I finally solve a Killer Sudoku puzzle. I felt thrilled when I solved this Killer Sudoku puzzle.

How to play Killer Sudoku: The goal of Killer Sudoku is to fill in the empty cells, one number in each, so that each column, row, and region contains each number exactly once. The sum of all numbers in a cage (indicated by the dashed lines) must match the small number printed in its corner. No number can be repeated within a cage.
