Schrödinger Somedoku
(Published on 7. May 2024, 12:35 by gdc)
This puzzle is my first time setting with the somedoku ruleset from Blackjackfitz. I decided to mix in some yin yang, S-cells and fog for good measure. See below for an example puzzle. Thanks to all the testers.
- Yin Yang: Color each cell in red or green. Cells of the same color are orthogonally connected. Every 2x2 area contains both colors.
- Schrödinger: Fill every red cell with 2 different digits from 1-9 and every green cell with one digit. Red cells count as the sum of their digits for clues.
- Somedoku: For every row N and every column N there are exactly N unique digits. Other cells contain duplicates.
- Fog Of War: The grid is covered in fog. Placing correct digits in green cells reveals clues in the surrounding 3x3 area.
- Local Constriants: Normal Renban, Nabner, Kropki and XV rules apply.
Example Puzzle
This 4x4 example puzzle contains a nabner line with values 1,3,5,7. The 3,5,7 are composed of S-cells (1+2,1+4,3+4). Similarly, the renban also contains a 1+2 S-cell which completes the 1234 run. Row 1 contains only ones, row 2 contains 2 unique digits (12), row 3 contains 3 unique digits (124), and row 4 contains 4 unique digits (1234). The same is true for the columns. Note that the row N digits don't have to be the same as the column N digits. Rows/columns can contain any number of S-cells and both digits in S-cells count towards the number of unique digits.

Difficulty
According to testers, this puzzle should be right in the middle between 3 and 4 stars. Given that Somedoku is still a somewhat new constraint, I decided to round up.
Solution code: The digits along Row 7 (including the red cells, smaller digit first), left-to-right.
For row 3 of the the example puzzle, this would be 112412.

Smooth deduction and perfect clues. Undoubtedly masterpiece.

A brilliant combination of rules, tricky, original, very fun to solve!
I'm amused by davidemsa's comment that this comes "with a change to the usual dynamic of somedokus." It's true, and yet somedoku was only invented two months ago! It shows how rapidly things are evolving with sudoku variants.

Truly amazing masterpiece. I am new to schrödinger and the exactly N digit ruleset. But very satisfying fight for me. Thanks.

This is a masterful combination of some of my very favourite rulesets, including one that has only been around a few weeks, so this is incredibly impressive setting! Every point was fair and beautiful, and I sincerely hope to see this get a richly deserved CTC feature very soon!

You absolute madlad... I take this as a personal challenge. I will find a way to out Schrödinger you someday!

I really like this one. The schrödinger, yin yang and someduku aspects interact with each other in interesting ways, with a change to the usual dynamic of somedokus.

Excellent. Little bit tough to keep track of options, but puzzle itself isn't too difficult.
