Assorted Sandwiches Sudoku
(Published on 15. June 2020, 14:37 by stephane.bura)
Normal Sudoku rules apply.
A large number on the side of the grid indicates the presence of a sandwich in the corresponding row or column. A sandwich has two digits that act as its boundaries. The large number is the sum of all the digits between those boundaries. The boundaries are the two digits of the large number, in any order.
For instance, the 18 clue means that the digits between the 1 and the 8 in this column add up to 18.
The small numbers indicate how many sandwich boundaries are present in this row or column. A digit can be a boundary for several sandwiches but is only counted once.
In a standard sandwich Sudoku, this number is always 2; in this puzzle, it varies.
However, even if this number is bigger than two, there is at most one sandwich per row or column.
Enjoy!

Great puzzle! I really like puzzles where the solution path involves significant logical discoveries that require quite a bit of thinking to achieve while proving the solution a second time would be relatively fast. This is definitely one of those puzzles -- very satisfying!

I was motivated by Richard's no. 303 to solve this one, but this is harder...

Mir hat es großen Spaß gemacht, aber ich fand es ziemlich schwer, (was aber auch daran liegen kann, dass ich mich nicht sehr schlau angestellt habe ;) )

@Richard that is correct.

Do I understand the rules right: the small 6 on top of column 9 means that there are at least four sandwich boundaries in column 9 that belong to horizontal clues?

Precision about the number of sandwiches.
