Shifter Lines 112: Slingshots

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.

Slingshots: If an arrow is present in a cell, the digit in the cell the arrow comes from appears in the grid in the direction of the arrow at a distance of N cells, where N is the digit in the arrow's cell. I.e. if the arrow in R8C1 was a 4, that means the digit in R8C2 also have to appear in R4C1. If R2C8 was a 6 and R2C9 was a 5 then R7C9 would also be a 6.
