Pi and Sandwiches (Diagonal Sandwich/Numbered Rooms)

(Published on 4. February 2025, 13:11 by damo_89)

This is my response to the latest Setting Saturday prompt by Scojo. The prompt called for clues that normally go along a line to be placed diagonally, and I have chosen sandwich and numbered rooms. Consensus testing estimate was 2 stars for difficulty, see below for a hint for the stickiest section. Good luck!

  • Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column and 3x3 box
  • Diagonal Sandwiches: Clues outside the grid in black (above and right of the grid) are diagonal sandwiches. They give the sum of the digits sandwiched between the 1 and 9 on that diagonal. (A diagonal with a sandwich clue contains exactly one 1 and one 9)
  • Diagonal Numbered Rooms: Clues outside the grid in pink (below and left of the grid) are diagonal numbered rooms, and indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.
  • (For clarity, the 8 in the bottom right is a numbered room clue)
  • Ratio Dot: The black dot separates digits in a 1:3 ratio, i.e. where one is triple the other

I really enjoyed how the clues worked together, though the puzzle reduced to pure sudoku a bit earlier in the solve than I would have liked.

Loved this ruleset! Definitely gave me some ideas :)
The mid-solve proved quite tricky, pushing it more to a 3/5 difficulty.
