There’s a big green rectangle with some weird edges, and it anchors the grid. But there’s this weird rotating line careening wildly across the grid, with very different properties than the rectangle. It grabs a couple of points, but mostly takes its own path. Oh, and also a switch of sorts, a single black dot. I think of it as a circuit, with the peach line representing temporary wiring. But I’ve used that metaphor when naming other puzzles, so it’s time to pick names differently.
Note: Some testers considered this a 1 or 1.5 difficulty, while others rated it 2.5 at least!
Rules:
Normal Sudoku rules apply.
Each set of three consecutive digits along the hollow peach line includes one low digit (1,2,3), one medium digit (4,5,6) and one high digit (7,8,9).
Adjacent digits on solid green lines differ by at least five.
In cells separated by a black dot, one digit is double the other.
Estimated difficulty: 2 out of 5
