I guess when I'm solving sudoku I lean on "runs" being all 9 so I know which of the 9 go into certain spots
I'm sure I'm not seeing something that lets me advance, but I'm just stuck with a lot of cells with two options.
it's also not clear why some "runs" just connect adjacent cells. I assumed adjacency (across zones) didn't matter because of that but the puzzle warned me when I broke that rule.
>That’s a confusing explanation for something I hope you intuitively understand from the image above.
heh... not quite intuitive to me I guess
my confusion (as best as I can tell through the fog of confusion) is that adjacent cells seem to not be allowed to have the same number... and also there are a bunch of obviously adjacent cells with lines connecting only those two cells (but also a lot of obviously adjacent cells with no lines connecting them.) Those lines connecting only two plainly adjacent cells are confusing me.
