Sudoku is one of the most addictive number puzzles to hit the world. Millions of people from all walks of like have caught up with the Sudoku puzzle in every form and version that exists today. People can solve a Sudoku by themselves, or play against another person in a timed game.
So you have to ask… what is this Sudoku puzzle anyway?
Sudoku was invented in 1979 by a 74-year old retired architect named Howard Garns, who was also a freelance puzzle maker. It was a puzzle that had a grid that was partially filled with numbers. The solver had to fill in the rest of the cells with the right combination of numbers. The game first appeared on the New York publication Dell Pencil Puzzles and Word Games under the name Number Place.
Number Place was introduced in Japan in April 1984 by the Nikoli company in its paper, the Monthly Nikolist. Kaji Maki, Nikoli’s president, named the game ‘Suuji wa dokushin ni kagiru’, meaning ‘the number must be single’, or ‘the number must occur only once’. Later, the name was abbreviated to Sudoku.
The first computer version of Sudoku was Digit Hunt, created by Loadstar/Softdisk Publishing and released on the Commodore 64 console platform in 1989.
Another running version that still exists is Single Number, which was created by Yoshimitsu Kanai. Single Number is a computerized puzzle generator that first appeared in 1995 for the Apple Macintosh PC platform. A PDA version appeared in 1996, and the most recent version for the Mac OS-X appeared just last 2005.
Dell Magazines still publishes Number Place. But it has added two new Sudoku magazines, Original Sudoku, which highlights the original version of Number Place, and Extreme Sudoku, which is a more difficult version of the original game. Kappa publications prints the Nikoli Sudoku as Squared Away in GAMES Magazine. Various American newspapers like The Boston Globe, The Examiner, The New York Post, and USA Today also print daily puzzles of Squared Away.
Though Sudoku was very popular in Japan and the USA before, Europe virtually had no idea that the game existed. But thanks to a retired Hong Kong judge, Wayne Gould, Europe would also catch the Sudoku fever.
Gould saw a partially completed Sudoku puzzle in a Japanese bookstore in 1997. He bought the book, and created a computer program that could generate puzzles quickly and easily, developing it over 6 years in Pappocom, his software company. Then he promoted Sudoku to the British newspaper, The Times, because of its history of publishing puzzles. On November 12, 2004, the first Su Doku puzzle was introduced to the Britons. Pappocom’s puzzles have been printed daily by The Times since that day.
Various British versions of Sudoku then started popping up. There was Codenumber, The Daily Mail’s version, which was derived from Michael Mepham’s puzzles, and first printed on January 19, 2005. Sudoku puzzles were first printed by The Daily Telegraph of Sydney since May 2005. And when the British Telegraph introduced Sudoku daily on its front pages, starting in February 2005, other British newspapers started to take real interest in the game. Due to the popularity of the game, The Times published the first Sudoku book to gain its edge over competitors.
Due to the similarity of the logic behind Sudoku and the legendary Rubik’s Cube, Sudoku was dubbed as ‘The 21st Century Rubik’s Cube’. Because of its popularity, Sudoku was dubbed as 2005′s “fastest growing puzzle in the world”. Sudoku conquered not only the print media, but also broadcast and electronic media!
Channel 4 introduced the first TV Sudoku game in July 2005 when it included daily Sudoku puzzles in its Teletext service. The Radio Times, BBC’s program guide, started featuring Super Sudoku, a weekly puzzle game in August 2005. The Dutch mobile phone company Mobile Excellence International also released the first mobile phone version of Sudoku in September 2005 in Europe.
Sky One produced the first Sudoku TV show, Sudoku Live, which started airing in July 2005. Hosted by Carol Vorderman, Sudoku Live featured 9 teams composed of 9 players per team, representing different geographical regions, that had to solve the show’s puzzle. Each team had a celebrity member and 8 ordinary citizens. While the studio version was being played, home viewers had their own interactive version to play with.
CBS started broadcasting stories regarding Sudoku, including on the Early Show in summer 2005, and on the CBS Evening News in October 2005.
The US TV series HOUSE M.D. also showed Dr. House solving a Sudoku puzzle during an episode. Due to its addictive nature, Sudoku was banned on the set becasee the cast was constantly playing it.
Now, the Internet is teeming with millions of Sudoku versions, both online and offline, free and purchasable. With the billions of unique puzzles generated by computer programs, Sudoku puzzles will not bore a Sudoku addict for a quite a long time.
Who could’ve thought that a simple number puzzle on paper in 1979 would conquer the world like the common cold?
