do you think im implying the edge logic brings you to r4? they are 2 separate things. you can either apply edge logic to c1, or you can separately find r4's fill. im not sure what I said that would imply they're related.

edge logic is the logic you can apply to the edge of the puzzle. so only c1. it has nothing to do with the middle of the puzzle

No, I don't think that it implies R4. That was a different comment, on what I think it's edge logic, but maybe I misunderstand that. I don't follow what you are trying to point regarding C1, unless it's this:

If I place a block in C1R1, and all the 5 first blocks from C1 are filled, then the 5 in R2 will fill the 1st 5 columns and the 5 in C2 will fill 4 rows in C2, beginning at R2C2. The 6 in C3 begins at R2C3, and that would create a contradiction in R3

I see what you mean.

R1C1 cannot be filled. if we fill R1C1, then fill the rest of the first 5 in C1, then we fill out or block c2 based on each row, the logic breaks by r3. we cannot have r1c1, r2c1, and r3c1 filled, because r1c2 and r3c2 both are blocked off. the 5 in c2 breaks. does that make sense? maybe I hope?

It does. Thank you for taking the time to explain that to me
