Understanding Killer Sudoku:

The game board features dotted-line polygons called "cages," typically marked with a number in their top-left corner.

Core Rules:

1. Each cage's top-left number represents the sum of digits within that cage.

2. Digits may not repeat within any single cage.

3. For cages without sums, only the no-repetition rule applies.
