Perception Fog


Rules:
  • Standard Sudoku rules apply.
    Each row, column, and region in the grid must contain the digits 1 to 9 once each.
  • 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. 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.

"The quad circle clue is in ascending reading order"
For me this was a bit confusing. Maybe it's obvious how you read quad clues, but I was thinking maybe I can read in a circle.
Probably because I remembered a puzzle where the quads also defined the order read in a circle.
After I found out how to read them it was great!
I loved the negative constraints! :)

Great puzzle! More like a 1 star puzzle though

Really fun puzzle. Was suprised at the ease of the start and wondered why it was two stars. Then, I reached the middle :)

Thank you for a very good puzzle! This was my first full-kropki puzzle.

Got a lot easier after I revisited and finally read "All dots are given", thanks for bolding it! :)

Great puzzle! Got stuck at first bc I missed the negative constraint, but after that it was nice. Thanks for updating the rules to be more clear! I think this is a nice puzzle for beginners!

The start is fun, the rest is a bit easy but still enjoyable.
