I hope you will enjoy my fifteenth puzzle.
I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Arrow: Digits along an arrow sum to the number in the attached pill read from left to right or from top to bottom.
German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.
Equal-sum line: Each blue line in the grid has the same sum of digits (not to be confused with region sum lines).
Sandwich: A clue outside the grid gives the sum of the digits appearing between the 1 and the 9 in that row/column.

That was pretty fun! Wasn't terribly hard to work out the basics of each constraint: the arrows were simple enough, and that basically narrowed down the lines' sum immediately - but they all worked off each other pretty nicely!
