About Sudoku
Sudoku originated from the Latin square studied by Swiss mathematician Euler and others in the early 18th
century.In the 1880s, a retired American architect Howard Garns invented a fun puzzle game based on this Latin
square. This is the embryonic form of Sudoku.
In the 1970s, people discovered this game in a puzzle magazine
"Math Puzzles and Logic Problems" in New York, USA. It was called Number Filling at the time, and it was
recognized as the earliest published version of Sudoku. In 1984, a Japanese scholar introduced it to Japan and
published it in a game magazine of Nikoli. Later, a former New Zealand judge of the Hong Kong High Court, Wayne
Gould, accidentally discovered it while traveling to Tokyo, Japan in March 1997. .
He first published in the
British "The Times", and soon other newspapers also published, and soon became popular throughout the United
Kingdom. After that, he wrote a computer program for 6 years and put it on the website (this website is also
famous Sudoku player forum), the website was shut down due to some reasons. Fortunately, Sudoku master Glenn
Fowler restored the data, and the player forum has a new place.
