Even/Odd Sandwich
(Published on 23. January 2020, 01:52 by Phistomefel)
The usual Sudoku rules apply. A clue outside the sudoku grid indicates the sum of the digits that are in the corresponding column or row between the fields with the 1 and the 9 (the fields with the 1 and 9 do not count towards this sum).
If a regular field is marked blue, it contains an even digit. If a clue field outside of the sudoku grid is marked blue, the clue is an even number. It is also possible that the clue is an even number greater than or equal to 10, but not a 0.
The puzzle is also available online via Penpa Plus. Have fun solving!
Solution code: 2nd row, 4th row

Name geändert, weil Even Sandwich eine andere Rätselform beschreibt.

@uvo: Dankeschön! :) Und auch vielen Dank für den Hinweis - dann überlege ich mir einen anderen Namen für das Rätsel.

Beeindruckend, dass das aufgeht - zwischenzeitlich hatte ich alle Hinweise verbraucht und mich gefragt, wie das überhaupt eindeutig werden kann.
Übrigens: Der Name "Even Sandwich Sudoku" ist schon anderweitig vergeben:
