Hidden Arrow Sudoku
(Published on 28. November 2021, 14:00 by Prutsbeest)
Normal arrow Sudoku rules apply (i.e. digits along an arrow sum to the digit in the corresponding circle; digits may repeat along an arrow).
In this Sudoku, all arrows are hidden, only their circles are given. All arrows must be of length 2 (so each circle is the sum of two other digits).
Different arrows may not share a cell and may not even cross each other. Arrows cannot share a cell with a circle.
The nine given digits in green are digits that are NOT part of any arrow.

Very nice puzzle, I loved the logic. I also loved that I never felt blocked, because you can deduce things at multiple places at the same time, there is no mandatory order for most deductions.
Thanks for this wonderful puzzle!

Wow. Very nice. Easier than expected, but not really easy ...
Sehr schön. Leichter als erwartet, aber nicht wirklich einfach ...

Oh, this took me a long long time, there is just so much going on and all kinds of different deductions all over the place are needed. Awesome setting once again, thanks.

may not = darf nicht
daher ist die Übersetzung sehr unglücklich
Dürfen sich Pfeile nun kreuzen oder eine Zelle teilen oder nicht?

Hallo SKORP17,
Sorry für diese Verwirrung, mein Deutsch ist nicht so toll, ich habe versucht die Übersetzung zu verbessern.
Pfeile dürfen sich nicht kreuzen und Pfeile dürfen sich keine Zelle teilen.

Nice puzzle! I assumed that arrows may not use other circles, maybe that can be emphasized in the rules
