Here are some more ideas around ambiguity and box exclusivity. The rules should be fairly straightforward. Difficulty estimated at 3.25 stars.


Rules:

Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

Lines—Renbans / Whispers: Each gray line represents either a Renban line or a German Whisper line, such that:

  • Digits on a Renban line form a set of consecutive digits in any order
  • Adjacent digits on a German Whisper line differ by at least 5

Dots—White Kropki / Black Kropki: Each gray dot represents either a white Kropki dot or black Kropki dot, such that:

  • Digits joined by a white dot are consecutive
  • Digits joined by a black dot are in a 2:1 ratio

Box Exclusivity

  • If two gray lines appear in the same box, they must represent different clue types—one must be a Renban line and one must be a German Whisper line
  • If two gray dots appear in the same box, they must represent different clue types—one must be a white dot and one must be a black dot
  • For clarity, the dot between R7C67 belongs to both boxes 8 and 9, and therefore the other dots in those boxes must both be different from it. The same goes for the line at R5C234.
