SUDOKU
The Mind Game
Most of us are familiar with the math mind game “SUDOKU”. Here are few facts as to how it evolved. Sudoku has a fascinating history. "Su" means number in Japanese, and "Doku" refers to the single place on the puzzle board that each number can fit into. One way to describe the game is "Solitaire with numbers." It also refers to someone who is single. Its origins are actually European and American and not Japanese.
Sudoku first came to light in the 1970s in an American puzzle magazine. It was presented under the name, "Number Placement" .It later resurfaced in a Japanese puzzle and games magazine in 1984. Leonhard Euler, Swiss mathematician, developed the concept of "Latin Squares" where numbers in a grid appear only once, across and up and down. Dell Magazines in the US began publishing them using the concept with a 9 * 9 square grid.
The president of the Japanese puzzle giant Nikoli, Inc., Mr. Maki Kaji published the puzzle and it became a huge hit. He gave the game its current name, and helped refine it. He restricted the number in the puzzle to 30 and had them appear symmetrically. It soon became a fixture in daily newspapers and magazines. Yet almost two decades passed before the game was taken up by The Times newspaper in London as a daily puzzle. This occurred due to the efforts of Wayne Gould, a retired Hong Kong judge. He first came across a Sudoku puzzle in a Japanese bookshop in 1997, and later spent many years developing a computer program to generate them. In the fall of 2004, he was able to convince The Times to start publishing daily Sudoku puzzles developed using his software.
There are 5 by 5 games, 6 by 6 and 7 by 7 games. For the truly addicted, there are even 16 by 16 grids, not to mention a 25 by 25 grid apparently offered.
Sudoku is a fun and challenging way for people of any age and culture to hone their logical approach. Sudoku helps make the human race a tiny bit smarter through regular practice. Today there are Sudoku clubs, chat rooms, strategy books, videos, mobile phone games, card games, competitions and even a Sudoku game show. Sudoku has also sprung up in newspapers all over the world and is commonly described in the world media as the "fastest growing puzzle in the world".
