Rules:
Normal sudoku rules apply.
Little killer:
Arrows outside the grid show the sum of all digits between first 1 and first 9 in that diagonal as seen from that direction. The sum may include repeat digits. Not all possible clues are given.
Sandwich:
Arrows in the grid indicate the sum of all digits between 1 and 9 in that row/column. How does it work?
If a row/column contains 0 arrows pointing in it's direction, the sum of the digits between 1 and 9 in that row/column is 0.
If a row/column contains 1 cell with arrow pointing in it's direction, the sum of the digits between 1 and 9 in that row/column is equal to this clue.
If a row/column contains 2 cells with arrows pointing in it's direction, the sum of the digits between 1 and 9 in that row/column is equal to the two-digit number compiled from these two clues. (E.g. if the clues are 1 and 2, the sum can be 12 or 21.)
The puzzle doesn't contain sandwich sums with zeros or repeat digits (10,11,20,22,30,33).
All of those arrows are given.

Maybe my comments attract some solvers. Probably it was overlooked by many solvers in the sudoku flood...

It's a very nice puzzle with a smooth solving path. But only 3 solvers. It deserves much more attention.
