Q: What does Sudoku mean and who named it?

Maki Kaji, founder of Japanese-based logic puzzle company, Nikoli Co. Ltd., named the puzzle Sudoku.  Su means the number and Doku means single in Japanese.  It indicates bachelor numbers with a little sense of humor: “the single-digit number should be kept bachelor and unmarried.”  Kaji is known as The Godfather of Sudoku in the world because of his naming and his role of refining the original version to appeal the mass.  He was selected as one of “the 100 Japanese the world respect” in Newsweek Japan in 2006

Q: Who invented Sudoku?

It is assumed that the original form of Sudoku was designed anonymously by Howard Garns, an American based in Indiana.  The earliest version was published as Number Place in the puzzle magazine Dell in 1979.

Q: How did Nikoli find the original version of Sudoku?

Kaji’s encounter with the original version of Sudoku dates back to 1979.  His friend who took a trip to the U.S. brought back a puzzle magazine Dell as a souvenir.  A puzzle called Number Place in the issue intrigued him.  The puzzle was too complex and created a new refined version in which each number worked as a clue in finding the next one.  He introduced the modified version in 1984 and it became widespread among Japanese readers.
