Red Lodge, Montana (Sudoku-Creek Hybrid)
(Published on 24. December 2023, 17:10 by mathpesto)
Rules:
Place the digits 0–8 once each in every row, column, and 3x3 box. A digit in a circle must appear at least once in the four surrounding cells. That digit also equals the number of surrounding cells that are shaded. A “?” represents the same number for both clues within a circle (i.e. that digit appears and that many cells are shaded). The value of “?” may differ between circles.
Unshaded cells in the grid must be orthogonally connected, and unshaded cells that are orthogonally adjacent must have digits that differ by at least 5.
Solve online:
Solution code: Digits in shaded cells in Columns 2 and 3 (top to bottom)

Enjoyed my stay at this puzzle. I found it harder than when I first solved it after it was on CTC, as far as I can recall. One very tricky step for me.

Innovative and challenging (for me), but very fun. I'd like to see this one on CTC.
