Number Placeやfigure placeという名前のパズルを、日本のパズル会社が「数字は独身に限る」を略して数独として発表したのが始まりです。 日本では商標登録されているのでこの会社が作成したものは数独、それ以外はナンバープレースなど別の呼び方が使われています。 海外では商標登録されていないのでSudokuという名称をよくみかけます。

The puzzles named Number Place and Figure Place were first published as Sudoku, short for "Numbers are for singles", by a Japanese puzzle company.
In Japan, the name Sudoku is registered as a trademark, so puzzles created by this company are called Sudoku, while others are called Number Place.
In other countries, the name "Sudoku" is not registered as a trademark, so the name "Sudoku" is often used.
Since 1996, Japanese-Online has been provided as a free service from PSPinc with the purpose of providing resources to individuals interested in learning about the Japanese Language and culture.
Japanese-Online has content suited to varying levels of study, including lessons for beginners as well as lessons tailored for those who need grammar and writing resources. Lessons are best suited to those who have basic understanding of hiragana and katakana alphabets before moving on to the more advanced grammar and particle lessons. Grammar lessons focus on learning about writing and creating more complex sentences and most lessons will not use romaji (Japanese sounds written with roman letters). Kanji is used in the lessons with hiragana and English translations provided.
