Sudoku is one of the most popular puzzle games in the world, played and enjoyed by millions of people for its simple rules and complex problem-solving challenges. But how did Sudoku develop to this point?
The history of Sudoku dates back to an 18th Century Swiss mathematician’s game called “Latin Squares” (according to this article from the Economist) and some of the first number puzzles to appear in newspapers were published in France in 1895. But the modern game of Sudoku as we recognize it today was invented by Howard Garns, a freelance puzzle inventor from Connersville, Indiana, USA in 1979 when it was published in Dell Pencil Puzzles and Word Games magazine.
