The beginnings of Sudoku
- In 1783, a Swiss mathematician made 'Latin Squares,' which was described as magic squares.
- The Dell Puzzle Magazine published the puzzle Number Place in the late 1970s.
- As Dell continued to publish the puzzle through the Eighties quietly, it was imitated and embraced in Japan. Publisher Nikoli made two small improvements and renamed it Sudoku. 'Su' means a number, and 'doku' translates as singular.
