Indigestion
- Kropki dots
- Renban lines
The brief
- Normal sudoku rules apply. - Renban line: Digits along each Renban line must form a set of non-repeating consecutive digits in any order. - 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.
