Today's Puzzle:

I should have asked for a million dollars at the end of the last video. Here is gUBBLOR delivering a harder puzzle with the same new variant just as I asked in the previous video. Enjoy it!

Shifter Lines 102: Lock the killer in the cage by gUBBLOR https://tinyurl.com/SudokuSleuthShifterLines102

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.

Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.

Killer cages: The digits in a cage must sum to the number printed in its corner. Digits may not repeat within a cage.
