Fog of War Sudoku

Fog of War. Only the cells you have placed and their immediate neighbors are visible; the rest is fogged.

How to play

Fill the 9×9 grid so every row, every column, and every 3×3 box contains the digits 1 to 9 with no repeats — the classic Sudoku rule. Fog of War Sudoku adds one twist: Only the cells you have placed and their immediate neighbors are visible; the rest is fogged.
