Sudoku
数独 · sūdoku
Japanese
“The number puzzle that conquered newspapers wasn't invented in Japan — but the name is pure Japanese.”
Sudoku (数独) means 'single number' — from sū (数, number) and doku (独, single/alone). Each number must appear alone in its row, column, and box.
The puzzle wasn't Japanese. An American, Howard Garns, created it in 1979 as 'Number Place.' A Japanese puzzle company renamed it sūdoku in 1984, and that name stuck globally.
British newspapers introduced sudoku to Europe in 2004. Within a year, it was everywhere — the fastest-spreading puzzle phenomenon in history.
The Japanese name gave the puzzle exotic appeal, even though it was American-invented and European-popularized. Marketing sometimes trumps origin.
