Shifter Lines 116: A multitude of constraints (with fog) by gUBBLOR & Jasura https://tinyurl.com/SudokuSleuthMultiConstraints

Rules:

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Shifter lines: Adjacent digits within the same box on a shifter line share both parity (even/odd) AND polarity (low/high). Whenever the line enters a new box either the parity OR the polarity shifts, never both. Shifter lines can never have 5 on it. Digits may repeat on lines.

Region sum line (box 1+2): Digits along the region sum line have the same sum in both boxes.

Kropki dots (box 1+4+5): A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values.

German Whisper (box 2+3): Adjacent digits along the German Whisper line must have a difference of at least 5.

Zipper line (box 2+5): Digits an equal distance from the center (the cell with the dot) of the zipper line must sum to the digit in the middle of the line.

Renban (box 3): Digits along the renban line must be a set of consecutive digits in any order, and must not repeat.

Killer cage (box 3+6): The digits in a cage must sum to the number printed in its corner.

Parity line (box 4+5): Adjacent digits along the parity line must alternate between odd and even.

Palindrome (box 4+7): Digits along the palindrome line read the same forwards or backwards.

Dutch Whisper (box 5+6): Adjacent digits along the Dutch Whisper line must have a difference of at least 4.

XV (box 5+6+9): Adjacent cells connected with the X must sum to 10. Adjacent cells connected with the V must sum to 5.

Between line (box 7): The cell between the two filled circles must have a value between those in the circles.

Arrow (box 8+9): The digits along each arrow must sum to the digit in the circled cell.

Thermometer (box 9): Digits along the thermometer must increase starting from the bulb end.

Fog of war: The grid is covered in fog. Placing correct digits will clear the fog from the surrounding cells.
