Rules
- Normal Sudoku rules apply.
- Sets of three adjacent digits along a teal Modular Line contain one number from each residue class modulo 3. In other words, one each from the following groups: (1,4,7), (2,5,8), (3,6,9).
- Digits separated by an X sum to 10. Digits separated by a V sum to 5.
- Digits separated by a white Kropki Dot are consecutive.
