Hot and Cold
(Eingestellt am 21. Januar 2023, 04:06 Uhr von brennan77)
Jede Zeile, Spalte und Box hat genau eine heiße Zelle (hat einen Wert von eins größer als ihre Ziffer) und genau eine kalte Zelle (hat einen Wert von eins kleiner als ihre Ziffer). Jede Zahl von 1 bis 9 kommt in genau einer heißen Zelle und genau einer kalten Zelle vor.
Zellen in einem Killerkäfig summieren sich zum Hinweis, falls angegeben.

I believe this puzzle has two solutions unless you assume that no cell can be both a Hot and Cold cell simultaneously. (Presumably, the hot and cold modifiers cancel out, and the value of the Hot/Cold cell remains unchanged.)
The rules heavily imply that this cannot happen — both by not defining how the value works in that situation and by stating that "each box has exactly one hot cell AND one cold cell." But I think one could argue that a single cell being both Hot and Cold technically satisfies that requirement. Personally, I would prefer if the rules explicitly forbade this situation. I never assumed it, and it probably made my solve a lot harder. :)
Outside of that, great puzzle, and I had a lot of fun!

Terrific hot/cold puzzle with some tricky moments!
I was stuck for a long while because I kept making a silly error. I hope you don't mind if I share the link with the embedded solution to help future solvers — https://sudokupad.app/huqhh3uhac

This is a really fun rule-set and a wonderful execution - some tricky bits of logic in there. Well done!

Another excellent puzzle. I loved the mid solve disjoint logic. Thanks for setting :)

This was one of the more challenging and frustrating and ultimately rewarding puzzles I've completed. I had to restart 4 times, I think. This was the first puzzle I've solved which forced me to devise new logic and approaches. Very cool, I hope to see more of this hot/cold ruleset. Well done, thanks for setting!
Brennan77: Thanks so much! Working on another now. I think this one was so tricky because it's not as good as the other, lol

I think I finally have it figured, how to set a new puzzle here...

I kept getting stuck on where the hot and cold cells went in box 8. Finally got that figured out and the rest of the puzzle went forward pretty well.
Thanks!
