Bose-Einstein Condensate (S-cells)

(Published on 18. January 2022, 17:34 by purpl)

Many people have been refering to the puzzle as "BEC" which is easier to type. This puzzle is my first attempt at Schrödinger cells sudoku, a variant developed by starwarigami. Furthermore, zetamath encouraged me to try this variant out, helped me a bit with a definite ruleset, and streamed the puzzle right out of testing!

Rules:

Normal-ish sudoku rules apply. Put the digits 0-9 into each row column and box once each. In order to accommodate this, each row, column, and box will have one S-cell which contains exactly two digits. Both digits in an S-cell must satisfy all other constraints.

Digits along a between line must be strictly 'between' the circled ends. For example, circles 1 and 4 could be connected by a line containing only 2s and 3s, these digits could repeat.

Given digits are NOT s-cells explicitly.

Links: Today we only have a CtC link since f-puzzles doesn't cover the digit 0, I can generate a penpa+ link if people would like that as well. Please let me know in the comments.

CtC

Solution code: The digits in the Schrödinger cells from the first row to the last, with the lower of the two digits in each row entered first.

Excellent construction!

Clarification on given digits NOT being possible s-cells.

I would say "excellent work as usual," except this is outstanding even by your usual standards.

I went to school at University of Colorado, graduated in physics, and we had a BEC on campus...pretty neat. I could solve that math but I ain't doing this puzzle rn lol

Very nice, thanks!

A lovely puzzle! Some very nice deductions happening throughout, it was a treat to solve :)

This is an awesome puzzle that I butchered the solve of over and over again, but was compelled to keep coming back to! Thanks so much for helping popularise my original embryo of an idea

Very nice puzzle! I particularly liked that some of the S-cells couldn't be resolved until late in the path, which made them even more of a factor.

Between lines combine splendidly with these multi-digit cells. The logic is very approachable and a lot of fun. :-)

Those unfamiliar with the "Schrodinger cell" concept, should try this warm-up puzzle by Richard:

I admit when I heard this combo my reaction was "I don't think that pair will do much" but I was proven super wrong immediately as purpl managed to use the constraint combo beautifully over and over again.
