- Kropki dots
- Modular lines
The brief
- Normal sudoku rules apply. - Modular lines: Every set of three adjacent cells along a modular line must contain digits with three different remainders when divided by 3. - Kropki pairs: Digits separated by a black dot are in a 1:2 ratio. Digits separated by a white dot are consecutive.
