Desert Roundtrip Sudoku
(Eingestellt am 28. März 2021, 23:01 Uhr von Zilvarro)
Ein Forscher (grüne Zelle) besucht die Sudoku-Wüste. Glücklicherweise gibt es dort richtungsweisende Statuen (alle Zahlen außer 5) und eine davon steht direkt bei ihm. Er folgt der Richtung in der sie schaut (1=Nordwesten, 2=Norden,... siehe Bild) bis er an der nächsten Statue ankommt, dann läuft er weiter in deren Richtung und so weiter. Wundersamerweise kreuzt er dabei niemals seinen eigenen Weg, durchquert alle neun Oasen (5er) und kommt am Ende wieder genau dort an wo er losgelaufen ist.
Ziel ist, das folgende Sudoku zu lösen und den Weg des Forschers zu finden.

Da dies mein erstes selbsterstelltes Sudoku-Rätsel ist würde ich mich über Kommentare und Feedback freuen.

Wow, this was brilliant! Amazing puzzle for a first time setter, Zilvarro. Very creative rule-set, both challenging and fun. While initially apprehensive, I enjoyed it a lot once I found the break-in and made a little headway.

@MrBrain: Yeah, the break in is quite tricky. [HINTS] First, from only the rules themselves you should work out that some of the 5s will be quite restricted in how they can be passed. Then one area of the grid allows you to deduce the orientation of the loop. This knowledge can then be used to place the first few digits in another area.

I understand the rules fine. It's just that I didn't get very far with the solve. I was able to make some deductions at the start, but was not sure how to narrow the possibilities further. I see someone solved it, so I think this is probably a very nice puzzle, and a nice idea.

@henrypijames Both visiting the same cell twice and diagonal crossings are forbidden. There is a more technical version of the rules on the F-Puzzles Link, I did not want to bloat the post with two versions of the rules. You are right that an example would help clarify this.

What does "cross his own way" mean? Never visit the same cell twice (except the starting cell) or is the X-shaped twice-diagonal crossing also forbidden?
I think rules generally need to be technical in order to be precise - and the desire to present a nice, poetic narrative sometimes gets in the way of that. To solve this problem, the rules might need to stated twice - once in the narrative-oriented flowery language, then once again with cold, abstract, technical precision.
And a complete new ruleset would almost always benefit greatly from a concrete, visual example outlining what the rules demand and (more importantly) forbid.

@henrypijames Yes, every numbers except 5 is a staue, though not all of them will be on the path. Yes, the explorer usually changes direction every cell unless passing through a 5 (keeps previous direction) or when multiple consecutive cells on the path have the same number (only possible when moving diagonally due to sudoku rules).

All numbers except 5s are statues? So the explorer mostly just move one single cell?
Also, what kind of dessert is packed full of statues? It's experiencing more construction than the Stone Henge! ;)
