Parity Arrows
(Published on 18. February 2023, 23:34 by Oddlyeven)
Rules: Normal Sudoku rules apply. Place the digits 1 to 9 once each in each row, column and box.
Diagonals: Digits may not repeat on either main diagonal.
Odd/Even: Digits in grey circles must be odd. Digits in grey squares must be even.
Parity Arrows: Digits on an arrow must sum to the digit in that arrow's circle. Adjacent digits along an arrow, including the arrow's circle, must have different parity (odd digits must be next to even digits and vice-versa).
