Love the Kropki Corners!

This was a lot of fun! It reminds me of that one constraint that has "small white dot means one diagonal pair of adjacent, big white circle means both diagonals are adjacent"
But yeah, definitely prefer the dots.

Added correct orange lines.

es fehlen 2 orange Linien in Box 9 (R7C8-R8c7 R8C9-R9C8)

@SKORP17 Vielen Dank. Ich habe das Problem erst wenige Minuten vor meinem Sonntagsgottesdienst bemerkt. Deshalb konnte es nicht sofort behoben werden. Ich war mehrere Stunden nicht erreichbar. Friede sei mit Ihnen.
Thank you. I noticed the problem only minutes before having to go to church on Sunday. This is why it was not fixed immediately. I was unavailable for several hours. Peace to you. -Will Power

Very artistic. I voted for version with the dots. Oliver asks for more diagonal constraints puzzles.

@Fisherman MORE?! 8-) Try my puzzles "Bangers and Mash", "Equal and Opposite Reactions", "Proper Boundaries", "Proper Boundaries Revisited", "Vending Machine Coin Sorting", and "Queen's Gambit", or any of mine that have a Little Killer constraint, if you haven't already. Peace. -Will Power

@SigridJ Thank you for showing me that I omitted one orange line and dot that satisfies the uniqueness requirement. I missed it from my internal plans at first. -Will Power
