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

Very nice construction. The solve required some lovely deductions that made it 2* for me.
