(Extra)ordinary Arrow Sudoku

(Published on 1. May 2021, 13:33 by Richard)

Recently I have created a pile of arrow sudokus for a special occasion. On the hunt for nice entries, I think I have found something 'newish'. I have no idea if this is done already, but I incorporated a bit 'global' thinking in the type. I found this one too hard to use, so I publish it here. Curious to read if it is indeed a new idea.
Of course no trial and error is necessary for this one.
In case you did use trial and error: read the hidden comment with the fun you missed! :-)

Arrow Sudoku
Apply classic sudoku rules. Each circle contains a digit that is the sum of all digits on the adjoining arrow.

Solve online in F-Puzzles (Thanks to MavericksJD!).

Solution code: Row 6, followed by column 1.

Although Arrows are for sure not my favorite type of puzzles, I liked this one very much! Saw the intended entry after a few seconds I guess, the rest was easy!

Wirklich rein logisch lösbar. Es lohnt sich!

That was a wonderful puzzle to solve. Nothing was terribly difficult, but I also found the break-in without much issue. After that, everything unwinds wonderfully. Perfect pacing.

Not so hard, but very nice

I really enjoyed solving this one. I even figured out my mistake in the middle and recovered ... I usually scrap it and start over at that point ;-)

Glad I stuck this one out.

OK, thanks for clarifying about the hint. I'll try on my own. I'm sure you know this, but just in case, I've seen some puzzle sites put hints in ROT13 to avoid unintended spoilers.

Answer: yes, I am aware of that. A more elegant way can also be like in the 2014 Advent Calender (See for example: 00024J)

I understand you put a hint in the hidden comments? But, how do I see the hidden comments. At one point, I thought I learned that hidden comments are only viewable by those who have already solved the puzzle.

Answer: yes, the hidden comments are visible only after solving. If you want a hint beforehand: send me a PM in the forum.

Very nice, I solved it logically without any trial and error. The logic is very nice, thank you! ;)

Very beautiful puzzle and it's also not hard at all, everything is just resolved in a very satisfying way.

Added a line about (not!) guessing. ;-)

I received feedback that trial and error was used for this puzzle. That really takes the fun away! In an effort to add an interesting technique to players' toolkits, I highly recommend to search for the intrinsic logic. It's worth it!
For those of you who guessed, the nicest logic is written in a hidden comment now.
