Here’s another entry in my ‘Experimental fog’ series. Here I’m continuing to explore how fog clearance could itself be information, this time combining it with yin-yang rules.

Rules

Sudoku: Fill the grid with digits 1 to 9, so that each digit occurs exactly once in every row, every column and every 3x3 box.

Yin Yang Fog: The grid is covered in fog. Once the puzzle is completed, any unshaded cells will be revealed, and shaded cells will still be covered in fog. All shaded cells are orthogonally connected, all unshaded cells are orthogonally connected and no 2x2 region is entirely shaded or entirely unshaded.

Clearing Fog: Entering a correct digit in an unshaded cell will clear the fog:

  • in that cell;
  • in seen cells - any unshaded cells that can be seen from that cell in an orthogonal direction (with shaded cells blocking vision); and
  • around corners - any unshaded cells that are orthogonally connected to a seen cell

Unshaded Whispers: Any two orthogonally connected unshaded cells must have a difference of at least 5.

Kropki: Digits connected by a white dot are consecutive. Not all dots are given.

Given Digits: White digits are given, but have not been entered into the grid.
