Line of Symmetry
(Published on 13. January 2023, 03:29 by apiyo)
Normal Sudoku rules apply.
Draw an open-ended line in the grid that enters every box exactly once, never diverging or creating any enclosed loops. The line may move diagonally only. In box 1 the digits along the line sum to 10. In boxes 2 to 9 the line must visit all and only cells containing a multiple or divisor of the box number (excluding 1.) For example, in box 4 the line must visit the 2, 4 and 8 only. The start and end points of the line are to be deduced.
Kropki dots: Digits joined by a black dot are in a 1:2 ratio. Digits joined by a white dot are consecutive.
Odds: Digits in grey circles are odd.
Dutch Whispers: Neighbouring digits along a yellow line must differ by at least 4.
Difficulty: Testers rated between 3 and 4.5
Solution code: The digits that appear on the line, reading left to right, in rows 1, 2 and 8.

Nice puzzle. Needed some attempts since I stupidly got the divisors wrong in my head.
But after I got the line almost correct, I struggled as always with the normal soduko stuff.
But I love the logics.
-- thanks WallE! Glad you liked it. I know what you mean about Sudoku!

Are the yellow lines part of the line to be drawn - all, partial or none?
-- the yellow lines are independent. The main line is free to touch them or not touch them

--Updated as had accidentally removed the central 1 from the puzzle. Sorry!!
