Switch Sudoku

(Published on 29. January 2020, 19:42 by Phistomefel)

Switch is a variant of the killer sudoku.

The usual sudoku rules apply. The areas surrounded by a dashed line are called cages. Digits may not repeat in a cage. A number in the upper left corner of a cage indicates the sum of all digits within the cage.

A number outside the sudoku grid indicates the number of switches between odd and even numbers in the corresponding row or column. Here is an example of a switch sudoku on a 6x6 grid:



The red dots indicate the switches in the rows and columns with a clue.

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

Solution code: 2nd column, 6th column

@ManuH: Gute Frage! Das müssen sie tatsächlich nicht - die Wechsel können auch auseinander liegen.

Müssen die Wechsel wie im Beispiel aufeinander folgen?
