Indigestion
- Killer cages
- Anti-knight
The brief
- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Anti-knight: Cells that are a chess knight’s move apart cannot contain the same digit. - Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage.
