Even knights fear arrows
(Published on 19. November 2020, 19:09 by Phistomefel)
The usual sudoku rules apply. Additionally, cells that are a knight's move away from each other, may not contain the same digit. The number in a circle indicates the sum of the digits along every arrow originating in the circle. Digits may repeat along an arrow. A cell with a grey square can only contain an even digit.
The puzzle is also available online via F-Puzzles. Have fun solving!
Solution code: First and last row

Beautiful logic, equal pressure throughout the entire puzzle. Nice setting.

Wow this puzzle was brutal! I wasn't expecting the opening logic to be the easiest part - I got through the first bit fairly quickly and then spent a couple hours just grinding away at it. I got completely stuck right before the finish line and ended up having to brute force my way to the ending (missing the bit of logic that's explain in the hidden comments). Beautiful puzzle, thank you!

Another brilliant gem from Phistomefel !! Wonder how you manage to create these. Very satisfying on the whole. Thank you, Phistomefel!
PS : Apologies for the inadvertent spoiler ! Have deleted that part. Thanks.

Dankeschön, Tilberg! :) Mir ist an dem Arrangement auch noch (weit nach dem Konstruieren) aufgefallen, dass die drei grauen Quadrate in R5C4, R5C6 und R6C5 zusammen mit den unteren beiden Pfeilen wie ein lachendes Gesicht aussehen, das einem die Zunge (Kreis in R8C5) rausstreckt. ;-)

Übrigens noch ein kleiner Glückwunsch dazu, daß sogar das Arrangement der Pfeile wie ein gespannter Flitzebogen aussieht. Klasse!

@tenaliraman: Wow, thank you for adding this puzzle to your favorites!
@Statistica: Vielen Dank für das Lob!
@Wecoc: I actually thought about making everything after the entry easier, but it just felt so anticlimactic. I hope your knee gets better soon though. ;-)

Wow, how did 29 of you guys all manage to guess the 18-digit code? No way anyone could actually solve this thing :P

Once I had the central arrows basically done I thought it would be smooth sailing from there. Then I took an arrow to the knee.

Very nice. I don't know how you do it! I'm full of admiration.

Ganz toll!

The simplicity of the solve path and yet how difficult it is to get to it is just mindblowingly beautiful. Added this to my favourites. Just amazing!

Very nice, it will go smoothly after finding the entrance

Ein wirklich wunderschöner Einstieg, und wenn man schließlich beim reinen Sudokuteil angekommen ist, immer noch voller Überraschungen. Danke!

@Player: Thanks a lot for your praise! :)

@SenatorGronk: Nevertheless, well done solving this. It is a bit of beast.

Wow, even after getting past most of the arrows it took me way too long to spot the knight's move constraints to progress through the rest of the puzzle.
