Killer Sudoku
No givens! Use cage sums and Sudoku logic to deduce every number. Cages must sum to their total with no repeating digits.
Rules:
- Each row must contain 1-9 (no repeats)
- Each column must contain 1-9 (no repeats)
- Each 3×3 block must contain 1-9 (no repeats)
- NEW: Colored cages show sums in the top-left
- NEW: Digits within a cage cannot repeat
Fill cells so each cage sums correctly and Sudoku rules are satisfied.
