Cute!

Completely solvable by logic. Nice,challenging puzzle. Some internal edge logic (on the right) and affirmation logic (at the top and bottom left). Thanks for posting it!

Yeah, just checked again and it is solvable by logic, although I almost stumped myself a few times. I had to use some of that fancy internal edge logic a few times, but it worked out just fine. I wrote up my logic for solving through the puzzle just to make sure it was indeed possible.

Of course is logically solvable! Who's marking it as not?
Where can the 4 in R16 go?

After getting much of the bottom left done, I did internal edge logic on the 5 in C2 to put a dot in R16 C2. Then, since you should know by then that both the 4s in C4&5 can't both be in R20, you can mark R16 in C5 and 6 as black.

i also did what you did with the 4 clues at the bottom to mark r16c5-6 black but line logic still cant solve the rest

look at the remaining clues in c4-6 (they are all >1) and all 3 of them cant extend into r7 (at most 2 can, but 1 must go up into r5) so you can mark r5c6 as black
then it solves out with line logic

nice solve
no guessing

I needed to save this one and come back to it, but I did it, no hints and no guessing, very fun puzzle Nathan, thank you :)

Found to be solvable with moderate lookahead by jan.

bug's right, 4 in r16 doesn't finish it. fun solve!
