The brief
**Sudoku, Diagonal, Arrows, Kropki Pairs** - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Diagonal: Digits along marked diagonals cannot repeat. - Arrows: Digits along an arrow must sum to the number indicated in the circle from which the arrow emerges. - Kropki pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Digits in cells separated by a white dot are consecutive.
