FUN TIME
Are you tired of the puzzles you usually do? Sudoku is a new choice. Sudoku consists of the Japanese characters Su (meaning “number”) and Doku (meaning “single”), but it was not invented in Japan. It was created by Howard Garnes in 1979. The puzzle was first introduced into Japan by Nikoli Puzzle Company in 1984. In 1986, Kaji Maki, the president of Nikoli made the rules strict and clear. Soon in the same year Sudoku became popular in Japan. In November 2004, The Times, a British newspaper, first printed it in the newspaper. It became an international hit in 2005. Now Sudoku becomes very popular all over the world.
The rule of the puzzle is to fill in the grids (格子) so that every row, every line and every 3×3 box has the numbers 1 to 9. Here is a Sudoku. Please relax and enjoy. It’s fun!
