Context: I made this Killer Sudoku for the Puzzling Stack Exchange post under the same title which had asked for Killer Sudokus with the largest cage sizes. I came up with this construction with every cage having 7 cells. Link to the PSE post: https://puzzling.stackexchange.com/q/24865

Rules:

Normal Sudoku rules apply. In cages, digits must sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage.
