This is a Cipher Mystery Number Set Sum Skyscrapers puzzle. In addition to regular Skyscrapers rules, the number set consists of five distinct positive integers; five copies of each are to be placed in the grid so that no row or column contains two equal numbers. Numbers represent building heights; unlike regular Skyscrapers, however, clues indicate the sum of the heights of the buildings visible from the clue’s point of view rather than their number. Each clue is a two-digit decimal number; each letter stands for one of the digits 0 to 9, with different letters standing for different digits and no number starting with a 0.
