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.
- dhooper 2y agothe 2-cell long runs are explained by this in the article "Runs terminate on cells with an odd number of sides" runs are shown between all adjacent cells.
- dwighttk 2y ago>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.
