Thermo Sum Lines
- Kropki dots
- Slow thermometers
The brief
Normal sudoku rules apply.
All thermometers are slow thermometers, as well as region sum lines. Digits along these thermometers must either stay the same or increase from the bulb end, and sum to the same value in each 3x3 box the thermo passes through.
Digits separated by a white dot must be consecutive. Not all dots are given.
