Stishovite (collab with Wisteria Fall)
(Published on 23. June 2026, 01:52 by Bellsita)
This is a collaborative puzzle between me and Wisteria Fall under the supervision of XeonRisq.
Rules:
- Normal sudoku rules apply. Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Additionally, no digit may appear more than once on a particular clue type.
- There are no negative constraints of any kind.
- German whispers: Adjacent digits on a green line differ by 5 or more.
- Renban: Purple lines must contain a set of consecutive non-repeating digits in any order.
- Modular lines: Any sequence of 3 adjacent digits along a teal line must contain a complete set of residuals modulo 3, i.e: one from (1,4,7), one from (2,5,8) and one from (3,6,9).
- Parity Lines: Digits along a red line must alternate between odd and even.
- Killer Cages: Digits in a cage sum to the number in the top left if given (basically they are cages).
- Odd/Even: The gray circles contain odd digits. The gray squares contain even digits.
- Black Kropki: Cells separated by a black dot have a 1:2 ratio.
- White Kropki: Cells separated by a white dot must be consecutive.
Solution code: All digits in Row 5 (Left to right)
