Sudoku Puzzles

July 3rd, 2008 by admin

It seems that these days you can’t go anywhere without seeing someone working on a Sudoku puzzle. The Sudoku puzzle is perfect for whenever you have a few spare minutes and want to work out your “mind muscles”. Sudoku, sometimes spelled “Su Doku”, is a puzzle that originated in Japan.

People of all ages and from all backgrounds are finding that Sudoku is a great way to keep their mind active and thinking. Puzzles range from easy for the beginner to extremely difficult for the more advanced puzzler. Sudoku is very portable, so it is easy to indulge in a little bit of number guessing whenever you have a few spare minutes.

Sudoku is very easy to learn and understand, but it takes a long time to master. The main aim of Sudoku is to enter a number from one to nine into each cell on the puzzle grid. The most frequent layout of a Sudoku puzzle is a 9 x 9 grid that is made of sub-grids that are 3 x 3. Each of these sub-grids is known as a “region”. Depending on how easy or hard the puzzle is there will be various starting numbers in the cells. These are known as the “givens”. Every row, column, and region of the Sudoku puzzle can contain only one instance of each number (1 – 9). You complete the puzzle when all of the cells have been filled in with corresponding numbers. Remember, each row can only contain 1 instance of each number, and the same goes for each column and region (the smaller 3 x 3 sub-grid).

To complete the Sudoku puzzle requires a lot of patience as well as the ability to think logically. Make sure you do it with a pencil as you’ll need to erase and “tweak” your puzzle to get everything right. Sudoku is not just a mathematical or arithmetic type of puzzle. It works just as well if the numbers are substituted with letters or other symbols. However, numbers work best.

The bottom line is that Sudoku is a fun new puzzle game that has taken the world by storm. You can now find Sudoku in almost all of the national newspapers. The great thing about this puzzle is that the basic principle of solving it is really quite simple. All you need to do is fill in the grid in such a way that each row, column, and region contains the numbers one to nine.
