Everything Is Rihgt
(Published on 30. September 2022, 03:03 by DiMono)
Normal sudoku rules apply.
Normal Killer, Little Killer, Quadruple, Kropki, Thermometer, Palindrome, Maximum, Minimum, and XV rules apply. Red clues are each at least one of normal Skyscrapers, X-Sum, or Sandwich clues.
After solving the puzzle, save your solution, because it's time to solve it again as a Wrogn puzzle! All clues in the grid must be made invalid in the finished solution, and red clues cannot be any of valid Skyscrapers, X-Sum, or Sandwich clues.
To be considered invalid, the maximum cell must be less than at least one adjacent cell, the minimum cell must be greater than at least one adjacent cell, thermometers must not increase from bulb to tip, and quadruple circles contain at least one digit which does not appear in the surrounding cells. For cage totals, since 5 is not greater than or less than 5, < effectively becomes >= and > becomes <=
Additionally, when solving the Wrogn version, no digit may be the same as it was in the Right version. i.e. if R1C1 was a 1 the first time, it may not be a 1 the second time.
It is impossible to solve the Wrogn version without first solving it normally.
Solve in f-puzzles
Solve in CTC App - the quadruple circle obscures the total in the column 8 cage. It is < 12
Solution code: Rows 4 and 6 of the second (Wrogn) solution

Probably the hardest puzzle I've managed to solve, certainly the only 5 star difficulty one. Incredible puzzle!

I enjoyed the other wrogn puzzles, but I missed this one until CTC featured it. I'm so glad they did because I would have hated to miss out on such a beautiful puzzle.

I thought I had already solved this puzzle. It turned out that I was wrogn. :)
Now I went back and solved both puzzles and enjoyed them thoroughly. A wonderful puzzle in both versions, but the wrogn version is plain magic.

Revised Wrogn rules slightly

Commenting again because I've finally solved it. I think it's a mark of an excellent puzzle that I spent the better part of three days trying to finish this off because I was so intrigued that I couldn't give up. I can tell you it makes it much easier to solve if you don't make a mistake in the "rihgt" version first (it took me far too long to realise this). This was my first successful solve of a "wrogn" puzzle and it was quite pretty - I particularly enjoyed the palindrome disambiguating an X-wing of 9s early in the wrogn solve. Anyway this was a long comment but I thoroughly enjoyed solving this, thanks DiMono!

Amazing puzzle! Just wow!
My favorite part, though it's hard to pick just one, was the skyscraper in r5 (in the Wrogn version) doing some magic.
Loved it. Thank you so much!

Puzzle wasnt hard as such but cant believe how many mistakes i made. I restarted the wrogn probably 15 times. But i am happy that i persisted.

Can someone please explain further how the wrogn clues work? I am looking at R9C2, R9C6, R9C8. My thought is that all of them have to be 1 because any other digit will create a valid X-sum clue (>=3).
@peterkp: Wrogn clues are invalid versions of normal clues. The <3 in column 2 in the normal version means the x-sum, skyscraper, or sandwich sum must be less than 3 - as long as any of them satisfy that condition, the clue is valid. The wrogn version means that NONE of them are allowed to satisfy that condition. I hope that helps - good luck with your solve!

well damn. that was hard but really satisfying; amazing settng, thank you

Hi @dimono
Do the red clues change sign as well in the wrogn?
@bansalsaab: Yes. Otherwise they wouldn't be wrogn ;) Take care though that <3 doesn't become >3, it becomes >=3, because 3 is not <3 and would therefor be a correct wrogn clue.
--thanks. I just wanted to make sure before starting. I have been burnt with wrong assumptions a lot :-)

Thank you all for the lovely comments! This puzzle was very difficult to set, and I'm glad people are enjoying it. Thank you for choosing my puzzle to spend your time on.

Beautiful puzzle(s)! :-)

Great bits of logic. Constructing a 2 for 1 puzzle is truly a work of art.

Updated puzzle links to versions that include the wrogn rule clarifications.

Further wrogn clarification on > becoming <= and < becoming >=

Great piece of art. :)

Great construction and puzzle! thanks

Awesome puzzle! It's very easy to mess the "wrogn" part of it, though - it plays with the mind. To those who didn't solve the puzzle yet - recommend paying much attention to the fact that the opposite of "<" is not ">" but ">=", and so on.

Stunning puzzle based on a great idea with a beautifully clean solve path in both halves. Takes some finding though.

Very satisfied, made a fatal mistake with the rules a few times in the middle. Everything else went well, AWesome Puzzles, thanks DiMono!

Fascinating puzzle, enjoyed testing this yesterday!
on 30. September 2022, 05:32 by DiMono
Added clarification to the rules for the wrogn portion, and for a cage whose total is concealed in the CTC App version.

Very cool original puzzle, thank you :)
