I wanted to make some puzzles involving clues wrapping from one side of the grid to the other. This started as a proof of concept, but turned into something I quite like. I am currently working on a tougher, foggier version though...

You can attempt this puzzle at this sudokupad link

Good Luck!

Normal Schrodinger Sudoku rules apply: Fill the grid with the digits 0-9 such that no digit repeats in a row, column, or box.

S-cells: In each row, column, and box there is exactly one S-cell, S-cells contain two digits instead of one, and their value for the purpose of other clues is the sum of those digits.

Doublers: One cell in each row, column and box is a doubler. For the purpose of other clues, the cell's value is double the digit (or digits) in the box. Each digit from 0-9 appears exactly once in a doubler cell.

Kropki: Values in cells separated by a white dot are consecutive. Not all dots are necessarily given.

X-sums: Numbers outside the grid give the sum of the first X values in the corresponding row or column, where X is the value closest to the clue.

***How do large clues work???***
If the closest value is larger than 9, then the X-sum wraps back to the first value again.

e.g. If the row reads 63291508(47), with a doubled 6 to start and a (47) s-cell to finish, then the X-sum starting from the left would use 12 cells. The first nine cells sum to 51, then the clue wraps, the next three cells are 12+3+2=17, so the X-sum from the left would be 68. If starting from the right, the first value is 11. The first nine cells sum to 51, then the clue wraps, the next two cells are 11+8=19, so the X-sum from the right would be 70.
