- Whisper lines
The brief
Normal sudoku rules apply.
Along thermometers, digits must increase from the bulb end.
Adjacent digits along the green line must differ by at least 5.
Digits on a red line must be different parity (odd/even) from the digit(s) horizontally adjacent on the thermometer (e.g. R5C4 has different parity to R5C5, R4C4 has different parity to R4C3 and R4C5).
Additionally, adjacent digits along a red line cannot be consecutive or in a 1:2 ratio.
Cells in the same position within two 3x3 boxes cannot contain the same digit (disjoint sets).
Digits separated by a white dot must be consecutive. Not all dots are given.
