Although sudoku is often associated with Japan, its origin can be traced back to France in the late 19th century, where some newspapers published similar number puzzles based on magic squares. However, these puzzles were not very popular and disappeared after World War I. The modern version of sudoku was invented by Howard Garns, an American puzzle constructor, in 1979. He called it Number Place and published it in a magazine called Dell Pencil Puzzles and Word Games.
The game first appeared in Japan in 1984 where it was given the name Sudoku, which is short for a longer expression in Japanese Sūji wa dokushin ni kagiru which means, the numbers must remain single. Sudoku became very popular in Japan, where people buy over 600,000 Sudoku magazines per month. However, it only achieved viral fame in the West around 2004, thanks to the efforts of Wayne Gould, who devised a computer program to rapidly produce unique puzzles. He sent some of his puzzles to The Times of London, which printed its first one on Nov. 15, 2004. Other British newspapers followed suit, and within a few months sudoku had become a worldwide phenomenon, with the puzzles appearing in newspapers from the United States to Finland, South Africa to Costa Rica, and Israel to Singapore. By 2006 hundreds of sudoku books had been published, and addicts could be seen everywherein offices, on buses and trains, and on the beachworking with paper and pencil or puzzling over interactive sudoku that had been adapted to mobile phones, video games, and the Internet. In May 2006 Time magazine listed Gould as one of the worlds 100 most influential people.
The first sudoku world championship was held in March 2006 in Lucca, Italy. It was won by Jana Tylova from the Czech Republic. Since then, there have been many other sudoku events and competitions around the world, such as the World Sudoku Championship, the World Puzzle Championship, the U.S. Sudoku National Championship, and the UK Sudoku Championship.
