Logic Masters Deutschland e.V.

My last puzzle was a set of smaller puzzles, with the same constraint as this puzzle. It took me a looong time to find a grid which has symmetrically placed clues. There is actually a solution without the givens, but the solution path is not very nice, and thankfully, I could still make the grid symmetrical with these givens, which don't remove the nice logic in the puzzle. :)

RULES:
- Standard sudoku rules apply.
- Embedded x-sums rules apply: The sum of the first x digits in the direction of an arrow, where x is the digit in the same cell as the arrow, sum to a single or double digit number directly behind the arrow. Double digits numbers are entered in two cells, read from left to right for arrows pointing horizontally and from top to bottom for arrows pointing vertically. All valid arrows are shown.

Here are a few examples:


And this is the puzzle:


Enjoy!
