Apply classic sudoku rules.
Each digit within the 9x9 region represents a skyscraper of that height. Digits outside this region indicate how many buildings can be seen from that direction, where higher buildings block the view of lower buildings. The small numbers in the upper left corner of a cage indicate the sum of the digits in that cage. Within a cage all digits must be different.
