Ouroboros 2: Our Ouroborealis

(Published on 31. March 2021, 09:49 by MallowTheCloud)

Normal sudoku rules apply. For each box y, digits x in the box give the position of the digit y in the box corresponding to the position of the digit x in box y. In other words, digit A in position B of box C must match to digit C in position A of box B.

Puzzle can be solved at f-puzzles.



A completed, color-coded example 4x4 puzzle can be seen below for reference:



Special thanks to Scott Strosahl and Lucas Emanuel for helping me work through the logic of this variant, and to rangsk for help with the theory and with identifying possible solutions.

Solution code: An 18-digit string of values corresponding to column 1, followed by row 9.

@BMEP: Ha, thanks! Definitely was hoping to fool some people with that, since the logic actually screwed me up the first time, too!
