Sandwiched Japanese Sums
(Published on 29. December 2021, 21:38 by leftovercube)
Normal sudoku rules apply.
Japanese Sums - Clues outside the grid indicate the sums of the digits in contiguous blocks in that row/column. Cells in blocks should be shaded. Blocks must be separated by at least one unshaded cell. A '?' indicates a block with an unknown sum.
Sandwich - If a row/column has a known (non-?) clue, it acts as both a Japanese Sums clue and a Sandwich clue. Sandwich clues outside the grid indicate the sum of the digits between the 1 and the 9 in that row/column.
Disclaimer - the shaded cells do not form an image
Solution code: Row 5 left to right

I'm not normally drawn to sandwich sudokus, but japanese sums I struggle to resist.. A very smooth and (for me, surprisingly) enjoyable puzzle - thank you!
