Inverted

(Published on 28. February 2023, 16:24 by Niverio)

You come in expecting a regular puzzle, but now you feel slightly dizzy. And as you regain consciousness, you notice something odd. Wait... everything's odd.

A small word of caution: This puzzle does solve very much like a classic Sudoku. If scanning deductions are not something you enjoy much, I suggest solving some other puzzle.

Rules:
Sudoku: Place digits 1-9 to each row, column, and 3x3 box without repeats.
Liar Quadruples: A digit appearing in a white/black circle can NOT appear in any of the four surrounding cells.

Puzzle Links: I have created versions with both white and black circles, as each version has its up-/downside. My personal suggestion is that you solve the CTC version with black circles, but open it in the beta version (app version inverts the white text kinda weirdly and might be irritating for the eye). You can switch the app to the beta version by selecting the option from the menu in the top left.

You can't fool me, this is just a Pencilmark Sudoku with extra steps!

Really cool idea and nice flow. The scanning was not exhausting at all, it fell into place pretty easily and painlessly. Thanks !

Anti-quadruples, nice idea! Like a new (anti-)classic

Fun new variant, not too difficult. Didn't feel too heavy on the scanning, just had to work through overlapping corner marks which can be hard

That's some high-quality meme puzz right there x)
Anyway, that was lots of fun! The amount of back-and-forth interactions felt like almost off the chart :)

One of the best puzzles I've recently done! Thank you so much.

Really smooth and quite telegraphed first part!
The ending required more scanning but... I mean... you warned us!
