** TODAY'S PUZZLE **
We solved the original sudoku by Belamis with this ruleset a while ago and this is the latest in the series: the idea is that each constraint type must not have a repeated digit on it. It leads to some lovely logic and, although this is not the hardest puzzle we've ever showcased, it's right up there in terms of the amount of joy it'll give you!

Rules:
Normal sudoku rules apply. Kropki: Digits in cells separated by a black dot have a 1:2 ratio (ie one digit will be double the other). Killer: Digits do not repeat in cages, and sum to the small clue in the top left corner if given. Thermo: Digits along a thermometer must increase from the bulb to the tip. Dutch Whispers: Along orange lines, digits must differ from their neighbors by at least 4. German Whispers: Along green lines, digits must differ from their neighbors by at least 5. Parity: Along a red line, adjacent digits must alternate between odd and even. Each constraint type above may contain no repeated digits anywhere in the puzzle. E.g. If one Thermo contains a 5, then no other Thermo may contain a 5 etc. The grid is partially covered in fog. Correctly placing digits will clear the fog around that cell. No guessing is required.
