Sudoku Variants Series (230) - Odd/Even Count Sudoku

(Published on 8. May 2018, 00:00 by Richard)

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

Odd/Even Count Sudoku
Apply classic sudoku rules. A digit in a grey cell indicates the number of cells around it (horizontally, vertically and diagonally) that contain digits of the same parity.

Solve online in F-Puzzles or CtC-app (thx Nick Smirnov!)

Solution code: Row 2, followed by Column 8.

@Saskia: In Reihe 4, Spalte 8 ist ein graues Feld, das spezielle Bedingungen erfüllen muss.

Maybe the rules can be more precise by adding: same parity as the digit in the grey cell

Danke!

@flaemmchen: an odd digit in a grey cell indicates the number of odd digits around it. An even digit indicates the number of even digits around it.
(Only a 4 in a grey cell that is not at a border, indicates the number of odd AND even cells around it. :-))

Zum Verständnis: Wenn die Zahl im grauen Kästchen gerade ist gibt sie die Anzahl der geraden Ziffern rundherum an oder könnte es auch die Anzahl der ungeraden Ziffern sein?
