Skyscrapers

If you get tired of the same old brain exercise games, here's another good one that's fun: SKYSCRAPERS The premis is simple.  Each number (1 thru 4) represents a skyscraper that is that many floors tall.  The numbers around the outside tell you how many skyscrapers you can see from that point.  Your job is to fill in the numbers.  For example, if you put a #4 in the first square, you can only see one skyscraper from that point because 4 blocks the view of all less tall skyscrapers in that line.
