Rules:

1. Normal Sudoku rules apply.

2. (Dynamic Fog) The grid is covered in fog. Certain digits reveal parts of the grid when placed correctly; other correct digits may not clear any fog except in their own cell. No guessing is required.

3. (Lighthouse) Circles are orthogonal lighthouses. Squares are diagonal lighthouses.

A digit in a circle indicates the number of smaller digits it can see in its row and column combined, not including itself. Larger digits block the view.

A digit in a square indicates the number of smaller AND EQUAL digits it can see in all diagonal directions combined, not including itself. Larger digits block the view, while equal digits DON'T.
