Isolation Sudoku

(Published on 13. January 2020, 19:56 by Phistomefel)

This puzzle is a variation of the killer sudoku. The usual sudoku rules apply. In a bordered area, every digit is allowed to appear only once. If an area has a number in the top left corner, the digits in this area have to sum up to the number.

Additionally, all identical digits have to be isolated. This means that every digit is only allowed to appear in one of two adjacent areas, but not in both. Areas are adjacent, if they share a common edge - touches via corners do not count.

The puzzle is also available online via F-Puzzles. Have fun solving!

Solution code: 2nd row, 4th column

Die Sonne muss mein Gehirn ausgetrocknet haben. Ich finde meinen Fehler nicht. Ich habe eine schlüssige Lösung, lese aber immer nur 'falsch'.
