Who invented Sudoku ?

Howard Garns (1905 – 1989)

  • Sudoku was invented by Howard Garns, a 74 year old retired architect and freelance puzzle creator, and first published in 1979 by Dell Magazines as Number Place (the earliest known examples of modern Sudoku).
  • The name “sudoku” is abbreviated from the Japanese suuji wa dokushin ni kagiru, which means “the numbers (or digits) must remain single.” Now there are sudoku competitions across the globe, and variations of the puzzle often appear side-by-side the crossword puzzle in newspapers and magazines.
