California skyscraper sudoku
(Eingestellt am 12. Mai 2021, 09:02 Uhr von Shinya)
dies ist eine Idee, die ich schon vor längerer Zeit hatte. Ich kenne kein Rätsel mit diesen Regeln, aber es würde mich wundern, wenn ich der erste wäre, der diese Idee hatte. Kennt vielleicht jemand schon etwas ähnliches?
Der Name kommt von den "California rolls" beim Sushi - es ist also ein inside-out Skyscraper-Sudoku.
Viel Spaß beim Lösen!
Regeln:
Es gelten die normalen Sudoku-Regeln.
Hinweise in der oberen Ecke eine Feldes zeigen an, wie viele Hochhäuser von diesem Feld aus gesehen werden könnten, wenn die Zahlen auf den Felder die Höhe der Hochhäuser angeben würde. Niedrigere Hochhäuser werden dabei von höheren Hochhäusern verdeckt.
Beispiel:
Lösungscode: Zeile 5, Spalte 5

Fantastic sudoko. I rated it with 4 stars, a bit hard, but not too hard.

Thanks for the feedback. I'm honestly surprised how difficult it seems to be. I know I have a tendency to underestimate my puzzles, but when I verfied the puzzle, it was just flowing. Other puzzles required much harder work. But maybe I had the ideas stewing in my head for so long that I became just too familiar with the logic.

had to stay up late to finish this puzzle and do agree with Henrypijames about the difficulty rating 5*, although wouldn't call the search tedious. Had fun.

Difficult from start to finish, even though I understood the principal logic pretty quickly and didn't miss any special cases (which is rare for me). Elimination was still very tedious, even increasingly so towards the end. 5 stars difficulty for me.

Exactly

"[S]een from that particular cell" refers to the "found floor" (as opposed to the rooftop) of that cell, right? For example, in a 9-2-1 sequence, the 9 can't see the 1 even though it's much higher than the 2 between them?

Thanks a lot, these are indeed having a similar idea - but I still think that the mechanics are quite different. Will give it a shot.

@Shinya: You might be interested in the following puzzles (in chronological order) as they have a similar theme:
Chalb's 6x6 puzzle: id=00015K
My 8x8 Multi-way skyscraper sudoku: id=0004C7
Mark Sweep's 9x9 Panorama sudoku: id=0005RT
I look forward to trying this later on :-)

Added example

It indicates the number of skyscrapers visible orthogonally (up, down, left, right, no diagonals, as you assumed correctly). The height is not indicated directly, but can be deduced.
Would it help if I added a little example?

Excuse me: Does the number of skyscraper tips indicate the total height of all skyscrapers observed from the cell (up, down, left, and right, excluding diagonals)?
