Chase the Fog Away

- 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 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. - Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage.
