I noticed that I've never made a puzzle with outside clues apart from Japanese Sums. This simple X-Sums Sudoku is here to change that. Enjoy!
Rules:
Sudoku: Place the digits 1-9 exactly once in each row, column and box.
X-Sums: Numbers outside the grid indicate the sum of the first X digits from the direction of the clue, where X is the digit in the cell next to the clue.
Diagonal: Digits cannot repeat along the indicated diagonal.
Solution code: row 6

The mental gymnastics needed to break into this are inspiring.

Damn that was a sneaky yet neat opening trick there, followed by a smooth and satisfying resolution afterwards :)

Took me longer than it should but it was very smooth and really liked how you find the first digit. Great puzzle!

WOW and WOW again! I enjoyed this so much. I'm a relative novice compared to most people on this website and this one hit the mark between doable and challenging. I felt like I had to eek out each deduction at the beginning, and then as I got more comfortable with the logic, it just laid out. Beautiful!! Thank you for sharing.

This is my favourite version of my favourite X-sum logic :)

Lovely puzzle !

Agree with Niverio, a 3-star opening! After the initial break-in, very straightforward path to completion. Fun solve overall.

i loved how this made use of a similar word from your other puzzle "Fadenkreuz"!

A 3-star opening with a 1-star follow up is indeed a 2 star combination :P Lovely puzzle!
