Shifter Lines 118: Hot Arrows by gUBBLOR https://sudokupad.app/ig5oto3aw8

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.

Hot arrows: An orange arrow points toward a cell N distance away that has a value greater than N, where N is the digit in the arrow's cell.

For example, if R8C9 would be a 4, then R8C5 would be 5 or higher.
