Xtravaganza (S-Cell XV Sudoku X)
(Published on 26. October 2022, 09:00 by tallcat)
Normalish Sudoku rules apply: Every row, column, and box contains the digits 0-9 once each. To accomodate this, one cell in each row, column, and box is a Schrödinger cell - it contains two digits.
XV: The sum of ALL the digits in cells separated by an X sum to 10, or a V sum to 5. This can lead to non-standard X/V (e.g. An X with 0 on one side and 2-8 in a Schrodinger cell is valid). Not all Xs and Vs are necessarily given.
Sudoku X: Each main diagonal must contain the digits 0-9 as well as one Schrodinger cell to accomodate this.
Note: The two given digits are not in S-cells
Can be played online at CTC sudokupad
Solution code: The digits in each S-cell from row 1 to row 9 in order (lowest digit in each pair first). 18 digits, no spaces.

This was my very first solve on LMD. I wanted to try a Schrödinger puzzle after watching CtC but the ones on the channel seemed too intimidating. This one was challenging, but I just decided to go for it and glad I stuck with it. Great job.

Wild opening deductions and very surprisingly smooth for an S-cell puzzle!

That was beautiful!
It's my first S-cell solve, and I had to break it once, but I'm glad I gave it a second try, and got it correct this time.
I hope to see it featured. I feel it's not too hard, and a good ambassador for the genre.
Thank you, tallcat!

Very beautiful midsolve!

The two givens digits - are there guaranteed to be non-Schrödinger, or could they be part of a S-cell?
Reply: That is a good point and I have clarified it. Thanks!

Very clever! My brain may have partially melted, but it was probably worth it.
