Free Sudoku | Solve Daily Puzzles Online
Did you know? Actually, Sudoku aren’t Japanese puzzles at all. It’s American invented. Howard Garns created the free puzzle as Number Place in 1979 but died in 1989 before Japanese publisher Nikoli got a hold of it. The game didn’t really take off until 2004 though, when Wayne Gould convinced The Times in London to publish it. The name Sudoku comes from Japan and consists of the Japanese characters Su (meaning ‘number’) and Doku (meaning ‘single’) however, the famous puzzle apparently was not invented in Japan. Sudoku’s origins began in Switzerland, travelling to Japan by way of America.
