Dominoes in the Dark

- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Fog: Part of the grid is covered with fog. As correct digits are placed, the fog will clear from surrounding cells. - Cages: Digits in cages must sum to the value shown in the upper left corner of the cage. All cages in this puzzle are dominoes (exactly two cells). - Consecutive pairs: Digits separated by a white dot are consecutive. Not all possible dots are necessarily given.
