I really enjoyed how this one turned out, although it is quite a strange one. I would put the estimated difficulty somewhere around 3.5-4 stars. Hope you enjoy!



Rules:

  • Sudoku: Fill all cells with the digits 1-9 such that no digit is repeated in any row, column or 3x3 region.
  • Fog of War: The grid is covered in fog. Placing logically deduced digits into the correct cells will clear the surrounding cells of fog, possibly revealing more information.
  • German Whispers: Adjacent digits along a green line have a minimum difference of 5.
  • Renban: Digits on a purple line form a contiguous set of unique digits in any order.
  • Diagonals: Digits may not repeat on the two main diagonals.
  • Extra region: There are 9 circles in the grid that contain a full set of the digits 1-9.

Lovely puzzle. Was stuck for a bit because my colors interfered with seeing where the fog was but it was a very fun solve. Thanks!

Brilliant puzzle. Wonderful how the constraints played together. I was wondering how you were going to disambiguate the whole thing, and then boom :)
