Sudoku Variants Series (353) - Hostile Parity Sandwich Sudoku

(Published on 29. December 2021, 00:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every week. I will see how long it takes before I am running out of ideas.

Hostile Parity Sandwich Sudoku
Apply classic sudoku rules.
Clues outside the grid indicate all digits in the corresponding row or column that have - on both sides - neighbours of the other parity as the digit itself. Clues are placed in ascending order and not necessarily in the order they appear in the grid.

Solve online in Penpa+ (thx Henrypijames!)

Solution code: Row 1, followed by column 5.

Leichter als der Vorgänger, aber ebenso schön :)

Nice. Thanks

343 rather could have been the hostile PSS and 353 the friendly one, just based on the parity in its SVS number. :-)

Reply: never thought of that, but would have been suitable indeed! :-)
