Rules
Normal sudoku rules apply.
Cells that appear in the same relative position in their 3x3 box must not contain the same number [Disjoint groups].
Black dots join cells whose digits are in a 1:2 ratio. Not all dots are given.
Along green lines, adjacent digits differ by at least 5.
Solution code: Row 4

Very nice! I found a great step mid solve that made my solve time quick. Thanks

The disjoint set messed with my head. Easy start on the whispers but then spent a long time on the disjoint sets.

I think I tried this when I was too sleepy - I spent a LOT of time staring at things wondering what was next, only to discover it was a simple case of sudoku I had overlooked, ha ha. For actual technical quality, 2 stars of difficulty. Despite my self-imposed frustration, I had a lot of fun solving it.
