Shelley's Boxing Day Sandwich

(Published on 22. December 2023, 07:41 by Cogsplay)

Normal sudoku rules apply

Place the digits 1-9 in every row, column and 9 cell region.

Pink Renban lines: lines do not branch and contain non repeating consecutive digits in any order.

Black Kropki dots: between digits with a 1:2 ratio.

White Kropki dots: between consecutive digits.

Sandwich sums: numbers outside the grid give the sum of the digits between 1 and 9 in their respective row or column.

Additionally the grid is covered in fog, which will clear as correct digits are entered.

I think the non branching constraint is only needed for the initially visible renban lines. For some reason the CTC link doesn't show the non branching constraint (does it need a refresh update too?)

Very nice. I really enjoyed the solve. Many thanks. About 1.5 stars of difficulty for me.

Beautiful design, loved this! The shape of the regions led to some really satisfying deductions.

Did you miss the possibility for Renbans to branch?
Otherwise I don't think this should be 1-star because I can't see a way to solve this.

@Felis_Timon you are correct. I will update the rules to say non-branching. Thanks for pointing this out.
