Normal sudoku rules apply.
Note: All lines have a maximum length of 4 cells.Dynamic fog - The grid is covered in fog. A correctly placed digit will clear any fog in that cell, and potentially in other cells as well. No guessing is required.
Sandwich Sums - Digits outside the grid indicate the sum of the digits found between the 1 and the 9 in the indicated row or column.
Anti-Kropki - Digits separated by a red ❌ are not consecutive and are not in a 1:2 ratio.
German Whisper - Digits along a green line must differ from their neighbors by at least 5.
Parity Lines - Digits along a red line must alternate between even and odd.
Renban Lines - Digits along a pink line must form a consecutive, non-repeating set in any order.
Region Sum Lines - Digits along a blue line are divided into segments with equal sums by the box boundaries.
Solution code: Column 9 from top to bottom

Great puzzle idea and beautiful execution, I do not understand why this is rated so low. Deserves higher rating. Happy New Year!

Hey Russ, this is very solvable. A few tips:
Start with the sandwich sums, then there will be a GW forced digit. Then another GW digit will play with the sandwich in column 3 and you have broken in the puzzle. The thing to remember from here is that every line has a max length of 4, which is necessary to solve the renbans that follow.

Is this solvable? I've never struggled so much with a 1-star puzzle.
