Sandwiches for Table Four

(Published on 22. March 2023, 10:25 by RockyRoer)

There's nothing worse than waiting tables and forgetting who ordered what... maybe you'll be able to sort it out?

The Rules:

  1. Normal Sudoku rules apply.
  2. Normal quadruple rules apply - in the four cells surrounding each circle, each of the digits must appear at least once.
  3. [Sandwich] - numbers outside the grid must be determined, and indicate the sum of the numbers in the cells sandwiched between the 1 and 9 in that row/column. Each quadruple's value must appear as a sandwich clue in one of the two rows or two columns that touch it.
    • For example, either row 8, row 9, column 6, or column 7 must have a sandwich clue of 31.

The Puzzle: Try on CTC or this link has a border on outside.

Solution code: Row 4 followed by column 4.

Very very cool puzzle. 4 stars for me. Like said above, it is hard to be a 100% certain about the logic you used. Luckily it all worked out :)

The part of the quadruple of the 19 and 17 and their sandwich structure is pretty interesting

Phenomenal puzzle, just phenomenal (and I was going to say, I think we have very different ideas of a 3-star difficulty!)

I cannot adequately convey the fear that sweeps over you as you unwind this puzzle; you just need to cross your fingers and hope your logic was sound.
