Mild Indigestion
- Kropki dots
- Arrows
- Kropki ratio
The brief
- 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. - Ratio dots: Cells separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.
