Arr Arr (Doubler Arrow)
(Published on 14. August 2022, 06:00 by ICHTUES)
- Digits on arrows sum to the number in its circle.
- Normal doubler rules apply; which means, that there are 9 doublers in the grid, one in each row, column, and box. Digits on doublers count as double their value. Each digit from 1 to 9 appears on a doubler exactly once.
Solution code: row 8

Oh, ok, thanks @uvo for the answer, and also congratulations on being multiple times world champion (saw it on the puzzle called Riesenhochhäuser).

@Yann: This question comes up occasionally, for example here:

Very nice puzzle, as somebody would expect from doublers. I really enjoyed the logic in boxes 2 and 3.
I just wonder whether it's possible to set a doubler arrow puzzle where every clue seems normal (for example, not like the straight 1-cell arrow). I set a small 6x6 with that extra constraint, and it turned out pretty well, the break-in is SET based, which can be cool with doublers. I wanted to publish it, but I don't know why I have to put my address on LMD to post puzzles. Can someone explain it ? Thanks.
And also thank you, ICHTUES, for setting this

What a beautiful puzzle with so many lovely deductions from the doublers ! I really enjoyed this one.

Mit den Dopplungszellen tue ich mir normalerweise schwer. Hier lief es wie am Schnürchen. Sehr schönes Rätsel. :)

I loved the last piece of logic and the implications of the position of the last double digit

Gosh, I love the doubler constraint. Brilliant execution and a challenging path which felt never too hard. THANKS!

Nice puzzle! It was my first "double arrow" and I quite enjoyed it.

Schöner Einstieg in die Variante.

A very clean solve that takes advantage of the doubler rule to the fullest degree! I enjoyed that a lot.

My first time solving a doubler puzzle. Uses the rule quite a bit, so it made a nice introduction for me. Break-in was approachable.
