Killer Sudoku

Enjoy playing Killer Sudoku or Sumdoku! Your goal is to fill the grid with numbers 1 through 9, ensuring that each row, column, and 3x3 box contains every number exactly once. Additionally, the grid is divided into colored cages, each with a specified target sum displayed in the top-left cell of the cage. The numbers within each cage must add up to that total, with no repeated numbers within the same cage.
