About Killer Sudoku:

The puzzle board contains dotted-line shapes known as "cages." Typically, a number is displayed in the top-left corner of each cage.

Rules:

1. The number in a cage's top-left corner represents the sum of all digits within that cage.

2. A digit may appear only once within any single cage.

3. For cages without a sum, only rule 2 applies.
