X-Sums
Solve online in F-Puzzles (thanks checkoway!) or in Penpa+ (thanks panthchesh!)
Platziere die Ziffern von 1 bis 9 in jede Zeile, Spalte und jeden 3x3-Block. Die Zahlen außerhalb des Gitters geben die Summen der ersten X Zellen von dieser Seite aus an. Dabei ist X die erste Ziffer aus dieser Richtung.
Lösungscode: Zeile 4, gefolgt von Zeile 6.

Not usually a fan of x-sum puzzles. Adding more than two single-digit numbers together seems to make my head fog up. But this one was approachable and enjoyable. Thank you.

My first ever x-sum and took me 1 hour 23 minutes. :( Fun but I definitely struggled!

Really enjoyed this - looked like it would be tough then suddenly freed itself up!

Thx for the comment.
For me this is a nice showcase how this variant evolved in the last decade; by today's standards it is extremely easy, and if I would write one today for the first time, I would also make it deliberately harder; but it is still a nice introduction example for this type I guess.

@patinthehat48: thx! For today's standards it's very much on the easy side, but back in 2014 the bar was a bit lower! :-)

One of the "smoothiest" SVS-puzzles I solved so far... thank you Richard!
