The brief
**Normal Sudoku, Arrow, Modular Line, Kropki Pairs** - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Arrows: Digits along an arrow must sum to the number indicated in the circle from which the arrow emerges. Digits may repeat along arrows if allowed by other rules. - Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3. - 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.
