Guessing is not required at any point, there are logical deductions to be found in order to clear the fog. The checker expects all outside cells that are part of a given clue to be filled, and all that are not to be left empty.

Good Luck!

The rules:

The grid is covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.

Skyscrapers: Each cell in the grid has a skyscraper, its height is equal to the digit in the cell. Taller buildings obstruct the view of shorter buildings behind it. Digits outside the grid equal the number of buildings visible in the row or column, looking from the clue.

Kropki: Values in cells separated by a white dot are consecutive. Values in cells separated by a black dot are in a 1:2 ratio. If a dot is in the centre of four cells, rather than between two cells, then both pairs of diagonally opposite digits satisfy the dot. Not all dots are necessarily given.

Killer cages: Digits in a cage sum to the total in the top left corner of each cage. Digits may repeat in cages if allowed by other rules.
