Up to now I've found no way to solve this puzzle. It's not logical, guess work and temporaries have been no help. Shame you didnt leave it at the first 'I'm watching'. This is terrible.
100% logical, requires a literal metric shitton of temporarys/3d logic first i made sure where the 14 in R1 couldnt go, then did the same with the 16 in R25, then alternated with the 8 and 6 in C21/22. that took alot of work with sometimes filling nearly half the puzzle to find the contradiction, but after a while everything falls into place.
Confused by the comments posted here. Totally logical. What did I do differently to solve this without temporaries or guesswork? Nice follow-up to v1 here. Thanks!
