Round n Round with Doppelgangers
(Eingestellt am 14. Februar 2024, 11:41 Uhr von bodemeister)
Big thanks to Kafkapharnaum, whose puzzles I have enjoyed solving, who taught me a useful trick about Penpa+, and who tested this puzzle! You can also check out my other puzzles here.
Links: You can solve the puzzle here at CtC or here at Penpa. Tracking cells are included to help disambiguate the doppelganger missing digits. Enjoy solving and please comment!
Rules:
- Doppelganger:
- Each row, column, and 3x3 box contains the digit 0 and eight of the nine digits from 1-9 (i.e. it's missing one digit that's not 0)
- Any two rows, any two columns, and any two boxes must be missing different digits
- For each 0 in the grid, the digits missing in its row, column, and box must be three different digits. - Killer: Digits in killer cages may not repeat and must sum to the number in the top left corner of the cage (if given).
- Kropki: Digits in cells connected by a white circle contain consecutive integers.
Lösungscode: The missing digit in each column, from left to right.

Nice coloring part at the end. Nothing too special about the start.

Really agree with kafkapharnaum. This one is far from being much easier than the Phistomefel puzzle #1! And my new knowledge (thanks to your lession!) was quite useful to solve this intricate and extraordinary work!
-----------------
Wow really? I thought this one was much easier. I guess the setter's mind is skewed. Thanks for solving and glad you enjoyed it.

Very beautiful puzzle. It took me a fairly long time, but once I found the logic at the end, I had such a great time unwinding it!
-----------------
Well done persisting and completing the solve! Thanks for the kind words and really happy you enjoyed it!

Nicely done, this was a pleasure to solve with a lot of doppelganger-specific logic and some pleasant symmetry!

Very nice and very hard, you easily forget that normal Sudoku logic does not apply :)
-------------------
Yes that is the hardest part of the doppelganger ruleset, but you pushed through and succeeded! Thanks for solving my puzzle and for your nice comment!

Incredibly puzzle this. Very impressive.
The minimalistic setup and symmetrical layout is very impressive, and the solve path is very smooth. Lots of very interesting and complex deductions in this one, which I really enjoyed.

Thanks a lot for solving my puzzle and for all the wonderful feedback! I just noticed you have also designed many amazing puzzles. I put some on my list to try to solve!

From its highly clever minimalistic opening setup to its bonkers last phase, this puzzle never stops to surprise and impress -- this is a very original take on the ruleset, and definitely not something I could have come up with myself. Would have been a pleasure to test either way, but this was extra special, so bravo and thanks so much for using the ruleset like that, and also of course for the (far too flattering XD) shoutout! :D

Thanks a lot for solving, testing, and the nice feedback. I feel your puzzles all have ideas I couldn't have come up with!
