Left, Right and Center (parity lines / sandwich sudoku)

(Published on 15. February 2023, 22:12 by Mr.Menace)

- Normal sudoku rules apply.

- Outside clues indicate the sum of the digits sandwiched between the 1 and 9 in the respective row or column.

- Red lines are alternating parity lines, and the odd/even parity alternates along a line. E.g. if r1c3 is even, r1c2 is odd, r2c1 is even, et cetera.

The puzzle is also available on SudokuPad. Have fun solving!

Solution code: 5th row and 5th column

From start to end, both the rules interacted really really well. The deduction in box 5 was particularly clever I thought.

Very nice! The interaction between the sandwich clues and the parity lines is crafted perfectly!

Very neat puzzle! Particularly enjoyed the initial breakthrough and the works around the 16 and 14 clues x)
