Sudoku puzzles: following the history
from: Wira Nuradli
Years before, barely anyone knew what the word sudoku is. The name sadako, a character from a Japanese horror movie is even more popular then. That was then and this is now.
In record time, the title sudoku became a household name not only in the United States but also in the United Kingdom and in other European countries as well.
Newspapers, both in the US and in the UK, have started to subscribe and feature sudoku puzzles in their pages. Websites dedicated on sudoku games have been put up. There are even forums that are created solely to discuss the game.
Sudoku is a number game that uses logic. It is composed of a 9 x 9 game board that has 9 columns, 9 rows and 9 bigger squares. In each of the bigger square, there are 9 smaller squares that the player must fill in with numbers 1-9. The difficult part of the game is that the numbers 1-9 must only appear once in every column, row and square. Since every square is interconnected, you really have to think before putting anything on a space.
The word sudoku is a combination of several Japanese words. Su means "number" while doku refers to the space in the puzzle where the number should be placed. There are some who claims that doku means single referring to the fact that the game is singularly played.
Although, the game became really popular in Japan and eventually gained ground there, there are reports that its origins is actually American and European. This perhaps explains the fascination that westerners have for this game.
According to history, sudoku was apparently developed by a Swiss Mathematics genius named Leonhard Euler. He called his 18th century creation the latin square where numbers appear only once across and down. In the 1970s, United States based magazine Dell published games that are similar in concept with the Euler grids. The magazine named the game section the Number Place. It was the brainchild of puzzle maker Howard Garnes.
It was only in the 1980s that Japan caught the sudoku game bug. Japanese puzzle giant Nikoli Inc. president Maki Kaji published his own version of the 9 x 9 grid puzzle, stating that only 30 clues should be given to the players and no more. It became a hit among the Japanese people, appearing in major newspapers and magazines in the country. It was also Nikoli that gave the name sudoku.
Two decades after, the Times newspaper in London started publishing sudoku puzzles inside their pages. It was due to the efforts of a Hong Kong judge that first saw the puzzles in a Japanese bookshop in 1997. Wayne Gould became so fascinated with the puzzles that he developed a software for it. The first game was published in November of 2004 and became hugely popular that other British newspapers followed suit and published their own.
The sudoku player today can actually find a mine of information in the World Wide Web. With just one click of the mouse, they can download sudoku games that they can enjoy everywhere they go. There are even programs that they can download which can generate different sudoku games everyday. What is more, they can choose the level of difficulty that will fit their competence in the game.
