Rules:

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

German Whispers: Adjacent digits along a green German Whispers line must differ by at least 5.

XV-Dominos: Cells separated by an X must sum to 10. Cells separated by a V must sum to 5. Not all Xs and Vs are necessarily given.

Kropki pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.

Fog: Part of the grid is covered with fog. As correct digits are placed, the fog will clear from cells surrounding the correct digit, revealing additional clues. There is always enough information in the revealed portion of the grid to place another correct digit without guessing. Digits can be placed within the fog.
