(Brief) History of Skyscrapers: Descended from other Latin Square puzzle types, Skyscrapers is a Japanese creation. It received its first broad exposure at the 1st World Puzzle Championship in NYC in 1992 when publisher Sekai Bunka-sha presented a 20 page English edition of their Puzzler magazine to the competitors.
