Rules: Standard sudoku and killer sudoku rules apply.
- The numbers 1-6 form a single orthogonally connected 1-cell-wide shaded region.
- There can't be more than three shaded cells in a row, i.e., no I-tetromino can fit fully inside the shaded cells.
- Numbers in diamonds indicate the total count of shaded cells connected vertically and horizontally to the numbered cell including the cell itself.
Here is an example of the rules: https://imgur.com/a/7kxLiQk
Solution code: Row 1 from left to right, column 1 from top to bottom (18 digits, with no spaces)

@bigger - (sorry I can't figure out how to respond to you privately!)
Q. Do 1 to 6 already shaded or only part of 1 to 6 are shaded
A. In the solution grid, every cell containing 1,2,3,4,5,6 is shaded, see an example solution https://imgur.com/a/7kxLiQk
Q. Can one cell wide region contain 2X2 shaded cells?
A. No. That's another way of writing the same rule.
