Sudoku Variants Series (390) - Double Arrows

(Eingestellt am 26. Oktober 2022, 02:00 Uhr von Richard)

Für dieses Sudoku-Varianten-Projekt habe ich geplant, jede Woche eine andere Sudokuvariante zu veröffentlichen. Ich werde sehen wie lange es dauert bis mir die Ideen ausgehen.

Double Arrows
Verwende die üblichen Sudoku-Regeln.
Die Summe der Ziffern auf einer Linie ist genau so groß wie die Summe der beiden Ziffern in den Kreisen die die Linie verbindet. Auf den Linien-Kreis-Kombinationen dürfen sich Ziffern wiederholen.

Dieses Rätsel ist von Zetamath's Diamond / Valence und tallcat's Split / Doppelt inspiriert.

Solve online in F-Puzzles or CtC-app (thx Steven R!)

Lösungscode: Zeile 1, gefolgt von Zeile 6.

With this one I have completed the whole SVS so far, within a timespan of exactly four months. Thank you very much for the logical roller coaster filled with different variants executed beautifully. It was a joy to see that these variants can be grouped in categories that have a common denominator in how to approach such puzzels. I am impressed you managed to keep this SVS running for almost 9 years already!
Reply: very well done!
You are one of only very few people who solved all SVS's in a long sequence. And even in a few months!
I agree with your observation that the different variants can be categorized by some generic constraints. Most variants can be placed in such a category.

Fun. As the others have said, it has a nice learning curve. Personally, I prefer to find my way into the puzzle first and then solve the problems that arise rather than not being able to start at all or only with huge difficulties. :)

There is an easy solution to this problem, Richard. Simply invent all new variants yourself. :-))
Reply: Thanks for the compliment!
So far, I have never thought active about a new variant myself, although of course I invented a few variants as well. In those cases the idea popped up naturally while being busy with something else. So I don't know what would be more time consuming; searching or thinking. :-)

Thanks for the nice feedback!
Sometimes I am in doubt about continuing with SVS in this overcrowded portal where shelf space is limited; your comments make the coin fall to the right side! :)

A very nice double arrows puzzle. A smooth and easy start with a modest increase in difficulty in the midsolve. A great introduction to the constraint!

This can serve as a great entry point to double arrows, but is also adequately challenging. Had lots of fun solving it! :)

So much fun, thank you!

A pleasant start, then it got quite harder later on but still all manageable, some beautiful deductions in there :)

Very nice puzzle. The start is easier than the end. Thanks a lot!

Extremely easy start, then gets suddenly hard in the midgame.
Reply: that was exactly intended! (And confirmed by testers as well. :) )
I thought long about a different opening than the inspiring puzzles. All four relied quite heavily on short lines and the interplay between those lines (and their circles). Therefor I wanted the break in with a long(er) line. And that was only possible with either a very hard opening or an obvious and easy one.
I thought it would be fun to save the harder work for later on in the solve and thus the easy start.
