Renban Sandwich Sudoku
(Published on 27. July 2021, 01:15 by zhergan)
Green lines are renban lines, i.e., they must contain a set of consecutive, non-repeating digits in any order.
Numbers on the outside are the sum of the digits sandwiched between the 1 and the 9 in that row or column.
Here is a link to the puzzle on f-puzzles.
Hint: Point symmetric cells according to the center (R5C5) always sum to 10 e.g. R9C1+R1C9=10, R4C6+R6C4=10, ...
Solution code: Row 8, followed by column 7.

I really was curious about "the hardest 2 star puzzle ever".
Well, without your additional clue I would have agreed. I never would have found the entry.
Very nice Sudoku now! Thank you for this one!

Hi to all,
I want this one to be really an easy one but it seems that I couldn't manage it. I wanted to give an extra hint for this puzzle. Since it means that being rude to the first solvers I want to apologize for doing so. I'm hoping that; this extra constraint would be helpful for solving and more people will give it a go. Sorry for the trouble again..

Yeah I've been wondering how this is 2 stars. I've starred at it for half an hour and got no idea whatsoever on where to start.

Hardest 2-star puzzle ever. Took me 3 hours and 51 minutes. And I am really, really curious if the path I followed is anywhere near your intended path.
