Quietly climbing with ratios
- Kropki dots
- Whisper lines
The brief
This is set 2 of the unique challenge. In this set, each puzzle is only allowed 2 variants and no variant can repeat. Good luck 🤞 Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Any 2 digits connected along a Dutch whisper line must have a difference of at least 4. Cells separated by a black dot has one digit double the other (1:2 ratio). Not all dots are given.
