How to Play Killer Sudoku

Killer Sudoku features the same 9x9 grid as Classic Sudoku, but with an exciting twist: there are no pre-filled starting numbers! Instead, the grid is divided into dotted outlines called "cages". The tiny number in the top-left corner of each cage represents the exact sum of the digits inside it. Most importantly, numbers cannot repeat within a single cage. Use arithmetic and logic (like the famous "Rule of 45") to deduce the correct placements.
