Kropki Sudoku has dots between cells: black = ratio 2:1, white = difference 1—what’s the trickiest Kropki Sudoku you solved (many dots, or overlapping rules), and how did you use dot rules to narrow numbers? Did you ever fill a 3-cell chain with Kropki dots in one go, and what’s the most ratio/difference-based Sudoku moment you had?
