- Kropki dots
- Arrows
The brief
- Normal sudoku rules apply. - 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. Not all dots are necessarily given.
