Dense Fog
Rules:
- Standard Sudoku rules apply.
Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each. - Little Killer rules apply.
The numbers on the diagonal are the sum of all the numbers on that diagonal. - Anti-Knight rules apply.
A number may not be a knight's move away from itself. - Quadruple rules apply.
Digits in the quad circle must appear in the surrounding four cells. The quad circle clue is in ascending reading order and duplicates are allowed. Some numbers have been replaced with a ?. It is up to the solver to determine (e.g. ?3?9 clue has a number between 1-3 inclusive, 3, a number between 3-9 inclusive, and 9) - Kropki rules apply.
A white dot joins consecutive digits. A black dot joins digits in a 1:2 ratio. Not all dots are given. - Dense Fog of War rules apply.
The grid is covered by a dense fog. Placing a number in the correct square will reveal ONLY that square.

It took me a bit of time to understand the quad circle rule, but flowed smoothly after that. Very nice.

Loved this one! The dense fog constraint made an interesting solve

I really enjoyed it!
(However, I was kind of devastated midway through it when I had coloured everything and it all looked so bright and confusing.)

WOW! Incredible puzzle… I’m pretty sure I did something wrong midway through though. Had to highlight every single digit repeatedly until I made some form of progress

The knight constraint always tricks me… anyway, very nice puzzle, very enjoyable

I liked it. Not sure it really needed the fog though.
