In the early days of the Sudoku craze, Sudoku used to be played with pen and paper. Commuters played Sudoku on newspapers on their laps, or in paper Sudoku books with dozens or hundreds of pages of puzzles. The reason for this legacy of pen and paper is because Sudoku used to be published in newspapers – in fact, the first number puzzles similar to modern Sudoku puzzles appeared in a French newspaper in 1895.
