Evolution of Sudoku:

               On July 6, 1895 a French newspaper called La France released a number game similar to this modern day Sudoku.

               For about a decade the French newspaper L'Echo de Paris published Sudoku weekly till the onset of World War 1.

              But it is considered that the modern day is designed by Howard Garns of USA. He first published it in Dell magazines. His age was 74 by the time of his invention. He was a retired architect and freelance puzzle constructor by that time.

             Later the puzzle was popularized in 1986 by the Japanese puzzle company Nikoli, under the name Sudoku, meaning single number. It became an international hit in 2005.
