Stingray (Odd) - Numbered rooms+Parity lines Sudoku
(Eingestellt am 11. Januar 2023, 23:02 Uhr von Qodec)
This puzzle is part of a duo. I'll decide later if I'm going to publish its counterpart Stingray (Even) on here as well.
- Normal sudoku rules apply: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Numbered rooms: Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction. Example: if r9c9 is a 2, then because of the 6 clue the second cell counting from the east to the west in row 9, r9c8, is a 6.
- Parity lines: Adjacent digits along each line must have opposite parity, i.e. one of them must be even, the other odd.

Lösungscode: Row 8. I.e. the 9 digits in row 8 from left to right, for example: 123456789

That was very tough! Possibly I missed something as I got stuck in the middle for ages.

nice but confusing solution code ... the 9 digits in row 1 from left to right ??? -> row 8 from C1 to C9.
