Skyscrapers + Dominoes (1146)
Instruction:
Put a full set of dominoes into the grid such that each domino occupies exactly two cells. (Cells may be left empty.) If two domino halves touch along an edge (and are not part of the same domino), then they must contain the same number. The orientation of the numbers does not matter. A full set of dominoes will be provided for your convenience; the smallest and largest numbers on the dominoes may change from puzzle to puzzle.
Each cell that is occupied by a domino half also contains a skyscraper of the same height as the number on that domino half. The numbers outside the grid indicate how many skyscrapers can be seen in the respective row or column from the respective direction; shorter and equal-size skyscrapers are hidden behind taller and equal-size ones.
Some numbers may be filled in for you; those are spaces that have to be occupied by a domino half with that number on it. Some cells may be shaded black, which indicates that they cannot be used by any domino.
