Vitreous (Renban/Little Killer)

(Published on 11. September 2026, 22:22 by damo_89)

I had an idea involving renban and little killer clues, and the puzzle almost set itself after that. I have tried very hard to make this approachable and am going to pitch as a 1 star. Good luck!

  • Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box
  • Renban: A magenta renban line must contain a non-repeating set of consecutive digits in any order
  • Little Killer: Clues outside the grid give the sum of the digits on the indicated diagonal
  • XV: Cells separated by an X sum to 10. Cells separated by a V sum to 5
  • Kropki: Cells separated by a black dot contain digits where one is double the other. Cells separated by a white dot contain consecutive digits
  • Not all XV or dots are necessarily given

Hint to Start

A 9 cell renban contains all of the digits 1 to 9, but a row of the sudoku also contains all of the digits 1 to 9, so can we associate cells on the renban elsewhere in the puzzle?

Solution code: Row 4

the essence of this puzzle can be expressed in one sentence.
the corner dominos see all but two cells of the long renbans.
the rest is basic sudoku
