Sudoku is a puzzle craze that has become increasingly popular over recent years. Some people have referred to Sudoku as the new Rubix Cube.  The Rubix Cube was a six-sided and six-colored puzzle cube which was popular during the 1980s.  Trying to solve the puzzle was very challenging and many people were unable to find the solution. 

The Sudoku game is not new.  It was created by a former architect named Howard Garns in 1979.  The game was published in an American puzzle magazine.  However, the Sudoku craze did not begin until 2005 when web sites, puzzle books and media coverage made the puzzle game a worldwide sensation. 

An ordinary Sudoku game puzzle is a 9×9 grid divided into nine 3×3 subgroups.  Some of the spaces have numbers and clues in them.  Other spaces are empty.  The goal of the game is to fill in the missing numbers in a logical fashion.  Each number 1 through 9 can only be used once and cannot be repeated in any square, row or column. 

Since the puzzle involves numbers you may think math is needed to complete a Sudoku puzzle. You will not have to add, multiply, divide, subtract or take the square root of anything. Sudoku does not require any math skills.  Instead, Sudoku is an exercise in logic and logic alone.  The Sudoku puzzle is all about reasoning.  Completing the Sudoku puzzle will give your brain a good workout.  The average time for solving Sudoku puzzles is between 10 and 30 minutes depending on the experience of the player and the challenge of the puzzle. 

The difficulty of the Sudoku is varied.  The puzzles can be crafted for highly experienced players or pure novices.  The very young can even get into playing Sudoku.
