Duplicity
(Published on 10. July 2023, 05:22 by zetamath)
Normal sudoku rules apply.
Normal rules for renban, German whispers, black dots, killer cages, arrows, thermos, and region sum lines apply. There are no negative constraints of any kind.
Have fun, leave a comment if you enjoy the puzzle!
PS: I stream solving sudoku like puzzles three days a week. You can check out the channel, as well as some videos I have made about setting puzzles, at my YouTube channel here.

Very cleverly constructed, and harder than I remembered (I had mostly forgotten that I had solved it before). Thanks.

Beautiful interactions all over the place!

Hi zetamath! This is the first time I have been stumped by a 3-star puzzle - oh dear! I've found several interesting restrictions, but they are quite minor, and do not seem to be enough to get the puzzle started. After playing with it for twenty minutes, I gave up, unwilling to bifurcate my way to a break-in. Are you able to provide a hint as to what I should be looking at first, by any chance? Thanks so much! HB.
[I recommend starting with the renban, quadruples, and the black dot in box 3. Note that the every length 4 renban has a 3 or a 6 and a 4 or an 8, which will put a lot of pressure on the box 23 renban. -z]
[Oh, I feel silly now, it seems so obvious! Thank you so much for taking the time to reply, I appreciate that gesture. Lovely puzzle, thank you. HB]

The interplay between the constraints was exquisite. Such a fun puzzle. Thanks as always, Zetamath!

Absolutely amazing ways of rewarding the solver for asking weird questions!

Loved this little scavenger hunt!

die Erläuterungen sind sehr dürftig (die Farben werden nicht erläutert und die Quadruples werden gar nicht erwähnt)

Lovely puzzle with clever interactions. Thanks.

Very nice - I was expecting some lying - turns out duplicity isn't as duplicitous as it might have been, not even nominatively :)
