Sudoku is a world wide craze requiring skill and analytical intelligence in order to accomplish the task of placing numbers between 1-9 in specific orders so that they do not repeat.
Wikipedia describes Sudoku as follows: Sudoku, also known as Number Place or Nanpure, is a logic-based placement puzzle. The aim of the puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called "regions"), starting with various digits given in some cells (the "givens"); each row, column, and region must contain only one instance of each numeral. Completing the puzzle requires patience and logical ability.
