(Published on 23. September 2020, 00:00 by Richard)
Pivot Sudoku
Inspiration for this type comes from stephane.bura.
Solve online in Penpa+ (Thanks stephane!).
Apply classic sudoku rules.
For cells with arrows, the first N digits in all directions of the arrows must have an equal sum, where N is the digit placed in that cell. Digits may repeat in sums with a diagonal direction. Not all possible arrows are given.
Solution code: Row 7, followed by column 4.

@geelow: if in R1C1 is a 2 for example, the sum of the 2 digits to the right equals the sum of the 2 digits below that cell. If it was a 3, it would be the first 3 cells for which the sums must be equal.

I don't understand the instructions. Can someone give me an example of how the arrows relate?

Ich habe mich glaube ich von der Beschreibung irritieren lassen. Es ist wohl nicht gemeint, dass ALLE Pfeile auf die gleiche Summe zeigen, sondern nur jew. die Pfeile in einer Zelle. Ein Beispiel wäre hilfreich.

Sorry to read that you are annoyed. But I shouldn’t know how to precise it even more. Examples are very rare in my puzzles since i think the rules themselves should be clear enough...
Do you still need more help for this one?
