This variant is quite tricky in general, but I’ve tried to make at least some of it relatively obvious. Either way, I like the combination, and I like how it turned out.
Rules – Follow regular Sudoku rules. Additionally, the clues outside are at least one of
1. Outside clues – The digit must be placed in one of the first 3 cells in that direction.
2. Skyscraper clues – Taking 1-9 as skyscrapers of increasing heights, 9 being the biggest, the clue shows how many skyscrapers can be seen from that direction. Bigger skyscrapers block smaller ones.
