Rules:

Normal Sudoku Rules Apply.

All the 1s are given digits. That's good news right? You will have to find them in the fog though, and where the 1s are hiding is particularly dense fog... eek! Go on, try it with that foggy cell in 'Box 1' that I've teased you with!

Each region/box has a different local constraint, with the constraint fully contained within that 3x3 box, from the following typical Sudoku variants (detailed rules available below):

- Arrows - German Whispers (Green) - Killer Cages - Kropki Dots - Nabner Lines (Gold) - Renban Lines (Purple) - XV Clues - Zipper Lines (Lavender)

The example lines at the top are just trying to be helpful, and the snowman is doing a great job too!!

== Constraint rules in detail (please feel free to skip if you are already familiar with the constraints) ==

Arrows: Digits along each branch of an arrow must sum to the value of the digit in the corresponding circle.

German Whispers (Green): Digits adjacent on a German Whisper line must have a difference of at least 5.

Killer Cages: Digits in a cage sum to the clue given in the top left corner. Digits cannot repeat within a cage.

Kropki Dots: Digits separated by white dots are consecutive in value. Digits separated by black dots have values in 2:1 ratio.

Nabner Lines (Gold): Digits on a Nabner line form sets of non-repeating digits where no digits can be consecutive with any other digit on the line.

Renban Lines (Purple): Digits on a Renban line consist of a set of consecutive numbers in any order, (and Renban lines do not branch!).

XV Clues: Digits joined by an X must sum to 10. Digits joined by a V must sum to 5.

Zipper Lines (Lavender): Pairs of digits an equal distance from the centre of a Zipper Line sum to the digit placed in the line's centre.
