     The Rubik's cube and its history 
    
    
     The Rubik's cube is one of the most famous 3D combination puzzles of our time. However
    this status was not the basic intention of its creator  Ernő Rubik  while
     designing it in  1974.

      Ernő Rubik is an Hungarian sculptor and professor of architecture. He worked at this
      time at the Department of Interior Design at the Academy of Applied Arts and Crafts in Budapest.
      As at this time computers were not yet the powerful and accessible machines that we know today, 
      Ernő Rubik wanted to create a teaching tool to help his students
      illustrate spatial relationships in 3D. This was the birth of the Rubik's cube. 
      However Ernő Rubik called it initially the "Magic cube" .   
     
     
      The first batches of Rubik's cubes were released in May 1980 and with the first 
     advertisements in televisions, the puzzle won rapidly in popularity.

     Already at the end of 1980 the Rubik's cube won a German Game of the Year special 
    award and also similar awards for best toy in the UK, France, and the US. The cube grew 
    in popularity worldwide and it is estimated that in the period from 1980 to 1983 around 
    200 million Rubik's Cubes were sold worldwide.
