- Whisper lines
- German whisper
- Kropki ratio
The brief
- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Anti-knight: Cells that are a chess knight’s move apart cannot contain the same digit. - German Whispers: Adjacent digits along a German Whispers line must differ by at least five. - Ratio dots: Cells separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.
