About Killer Sudoku:

The board contains dotted-line polygons called "cages," most of which have a number in the top-left corner.

Rules:

1. The number in the top-left corner of a cage is the sum of all digits inside that cage.

2. A digit can appear only once within a cage.

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