Für dieses Sudoku-Varianten-Projekt habe ich geplant, jede Woche eine einzigartige Sudokuvariante zu veröffentlichen.
Fibonacci lines
Dieses Rätsel ist von wafflefries inspiriert.
Solve online in Sudokupad.
Ich werde sehen wie lange es dauert bis mir die Ideen ausgehen.
Verwende die üblichen Sudoku-Regeln.
Das Gitter enthält Fibonacci-Linien, die von links nach rechts gelesen werden müssen. Jede Ziffer ist die Summe von den beiden vorangegangenen Ziffern. Wenn die Summe 9 überschreitet, dann wird die Summe als zwei separate Ziffern AUF DER GLEICHEN ZEILE geschrieben, in Leserichtung. Die erste Ziffer nach dieser mehrstelligen Summe wird dann wieder gebildet, indem man die beiden vorhergehenden Ziffern addiert.
Beispiel einer solchen Folge: 5-2-7-9-16-7. Diese Folge könnte nicht in der Linie platziert werden, die in R6C2 startet, da die 1 und die 6 dann nicht in der gleichen Zeile wären.
Lösungscode: Zeile 9

Das ist auch meine Erfahrung. Nach dem zweiten Rätsel von wafflefries flutschte es. Ich kann wirklich empfehlen die auszuprobieren.
That is my experience too. After the second puzzle from wafflefries it slipped. I can really recommend trying them out.

I haven't attempted it yet (waiting for some of my students to try it with me!), but I was thinking about trying "fibonacci arrows" with a 2 digit bulb (to designate the non-affected digits) and a direction (so the lines are no longer limited to just reading order).
Also, the break in, generally speaking, is pretty difficult. Once you "get" the puzzle, it becomes significantly easier to solve. 4* means you have a lot of first time solvers of the format. I would think that those who are already familiar with the format would rate it a 2-3*.

I am a bit surprised that this one has four stars for difficulty. Players give me feedback that they needed to guess. That is not necessary, although it might be helpful to make a few small tables with (limited numbers of) possibilities for some of the lines. To solve the five puzzles from wafflefries, I made a long table with all possibile starting combinations. After three of his puzzles, I didn't need that table anymore, since I had a click with the logic.
It also might help that I still solve puzzles with pencil and paper; it's easier to make notes.
Anyhow. I have written the way to start this puzzle in a hidden comment, in case you guessed your way through the puzzle. Which would be a pity...

Very nice puzzle. Found no way to finish it without breaking a line until this one wrong digit left its place.

Changed the link to the userpage of wafflefries.

Sorry, I overlooked this sentence. ;-/

Reply: no worries Gabi. I overlooked it while copying the text too. And it was fixed before it could lead to much confusion. :-)

Added missing German sentence. Thx Realshaggy!

The german instructions are missing the part where it says, that the line has to be read left to right.

I didn't notice that. Can you write the German sentence?

Is there a reason to use such an annoying link shortener for wafflefries Fibonacci puzzles, that redirects to the puzzle portal anyway? It takes ages pretending it is doing some "checks". (Probably it just lets you wait on purpose to show you the advertisement.)

Without a tinyurl the link doesn't work. I am not aware of another way to do this.
