- Kropki dots
- Modular lines
- Renban lines
The brief
**Sudoku, Duality Lines (modular/renban), Kropki Pairs** - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Duality Lines: All lines are both Renban AND Modular. - Renban line: Digits along a Renban line must form a set of non-repeating consecutive digits in any order. - Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3. - Kropki pairs: Digits in cells separated by a black dot are in a 1:2 ratio. Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
