Meta Unique-ish
(Eingestellt am 22. Juni 2025, 09:04 Uhr von Fenners)
Belamis has popularised the unique across each constraint types. I've taken that idea and added a little spin on it. Hope you enjoy and happy solving!
Puzzle: Meta Unique-ish
Rules:
Normal 9x9 Sudoku rules apply.
Meta Unique-ish: No two instances of the same constraint type may share digits.
Quadruples: In an orange circle, the question mark contains the set of all the (possibly repeating) digits appearing in the surrounding cells.
Renban: Digits on a purple line form a set of non-repeating consecutive digits, in any order.
Arrows: Digits on the tail of an arrow sum to the digit in the bulb.
Kropki: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio.
Lösungscode: Row 9, left to right, 9 digits no spaces:

What a puzzle! It took a lot of thinking about one of the constraint types.

Holy moly, that was a tough one for me! It took me almost 20 hours to solve it. The board looked like a clown with all my colours. I have been staring at the puzzle with ONE digit on it for 18.5 hours. Hahahahaha.
In the end, I got the right idea and then was "fairly quick" to finish the solve.
Now I am going to watch the CtC video and let Simon tell me how stupid I am for 45 minutes straight.
Going to be interesting to see the thought process by a pro.
Thanks for this heavy riddle :-)

My reading comprehension must be terrible today, because I need an example to clarify the rules. How is it possible to populate the 10 arrow cells without two instances sharing a digit?

No worries. Let’s say I’m thinking about the arrows: what it means is digits can repeat along an arrow, but once a digit is used on that arrow, no other arrows can use that digit. Hope this helps. —Fenners

Yes, thank you. That was actually really clear, I'm not sure how I didn't get it originally (especially because you included a one cell arrow!).

Amazing puzzle! Almost incredible how your twist works and can lead to surprising deductions. Thank you very much for creating and sharing this gem. I’m sure it will appear on the CtC-channel soon.

Thank you for this incredible construction, Fenners! It is one of the best puzzles I have solved lately. Not wanting to give spoilers, but especially the use of one of the clue types left me completely baffled.
