Nikoli (publisher)
Nikoli Co., Ltd. (Japanese: 株式会社ニコリ, Hepburn: Kabushiki-gaisha, Nikori) is a Japanese publisher that specializes in games and, especially, logic puzzles. Nikoli is also the nickname of a quarterly magazine (whose full name is Puzzle Communication Nikoli) issued by the company in Tokyo.[1] Nikoli was established in 1980[1] and became prominent worldwide with the popularity of Sudoku.
The name "Nikoli" comes from the racehorse who won the Irish 2,000 Guineas in 1980; the president of Nikoli, Maki Kaji, is fond of horseracing and betting.
Nikoli's claim to fame is its vast library of "culture independent" puzzles. An example of a language/culture-dependent genre of puzzle would be the crossword, which relies on a specific language and alphabet. For this reason Nikoli's puzzles are often purely logical, and often numerical.
Nikoli's Sudoku, the most popular logic problem in Japan,[2] was popularized in the English-speaking world in 2005, though that game has a history stretching back hundreds of years and across the globe.[3]
The magazine has invented several new genres of puzzles, and introduced several new games to Japan.
