Sudoku
From Simple English Wikipedia, the free encyclopedia
Sudoku (数独 sūdoku?) (also called Number Place or Nanpure) is a puzzle that is very popular in Japan. It was created in Indianapolis in 1979 by Howard Garns and it appeared in Dell Magazines afterwards.
To play, a person needs a sudoku grid (with nine rows, nine columns, and nine boxes that are separated by the thicker, darker lines) and a pen or pencil. Using the pen or pencil, the person must fill in all the empty squares without using the same number twice in each column, row, or box.
Many books have been created containing tips and strategies for completing sudoku puzzles.
