The brief
Standard sudoku rules: Each row, column, and box must contain a complete set of the digits 1-9. Killer cages: Digits within cages marked by dashed lines cannot repeat within the cage and must sum to the number in the upper left corner of the cage. XV: Digits separated by an "X" sum to 10. Digits separated by a "V" sum to 5. Digits not connected by an X or V may or may not sum to 5 or 10. Kropki dots: Digits separated by a white dot are consecutive. No negative constraint applies.
