Sandwich Clue Sudoku
(Published on 7. October 2021, 14:14 by Prutsbeest)
Normal Sudoku rules apply.
Sandwich clues outside the grid show the sum of the digits sandwiched between 1 and 9.
The little killer sum (47) shows the sum of the digits on the indicated diagonal.
Furthermore, digits in cells with a circle indicate how many of the surrounding cells (including the cell itself) are NOT 1 or 9.

Solution code: Row 4 followed by column 4 (18 digits, no spaces)

Nice idea but a pity the crusts had to be disambiguated by a little killer clue.
