To help many puzzle solvers wend their way through the confusion offered by some of the more difficult puzzles, a Sudoku worksheet may help them find the right solution. Many people solve puzzles by writing in suspected numbers in pencil and once they are determined to be the right number in the right box of the grid, will darken them, or go over them in ink. If the number is proven to be wrong, they can easily be erased and additional numbers added in with a pencil.
Sudoku worksheets can take many forms with some serious puzzle solvers laminating them and using a grease pen to mark suspected numbers into the respective boxes. The sheets can be used over and over again, but after a while, depending on the quality of the laminating material, may begin to deteriorate. Some of the more devoted Sudoku puzzle workers will use a dry erase board on their wall in order to have a Sudoku worksheet that can be used nearly forever.
There are also those players that make a multitude of copies of the same puzzle and throw them in the trash when each potential solution is proven wrong. Anyone can make their own Sudoku worksheet simply by designing a puzzle grid and clearly marking the nine regional squares, possible shading them to insure they know where each of the grids begins and ends inside the master nine by nine grid.
Worksheets Work For Serious Puzzlers And Newbies
The use of a Sudoku worksheet is not limited to only those learning to work with the puzzles. Many experienced at the puzzles find they can be very useful especially when working a puzzle at a higher difficulty level. When using a Sudoku worksheet the given numbers of the puzzle can be entered in pen so as not to confuse them with guesses, but all other numbers should be entered in pencil to make removing them easier when they are proven false in the equation.
There are many locations online where a Sudoku worksheet can be printed at home, usually consisting of a blank grid, which the user can use when working a new puzzle. The important aspect of using a Sudoku worksheet is to insure the initial clue numbers are entered in the right place on the grid, otherwise it could turn out to be an unsolvable puzzle. It is advised that when using a Sudoku worksheet, once the clues have been entered, the user go back and double-check their accuracy before attempting to solve the puzzle.

Sudoku is a game of the mind. Like chess it challenges, prods and encourages you to push yourself to your limits intellectually. Many people find this very attractive and that is why Sudoku today is such a popular game the world over.
A Brief History
Many say that Sudoku is a number game that originated in Japan. It is true that in the year 1984 (April) a monthly newspaper published in Japan by the name of Nikoli brought out the first Sudoku game, which was baptized at that time, “Suuji wa dokushin ni kagiru”. Later, it was shortened to what you know as “Sudoku” by Kaji Maki who was then the President of the newspaper.
Few however know that the Sudoku game was in fact first published not in Japan, but in USA by Dell Magazine. At that time this was called, “Number Place”. The father of Sudoku seems to be Howard Garnes who was inspired to come up with these puzzles by the Latin Squares or Magic squares.
The Latin Squares were the result of the work of a Swiss mathematician known as Leonhard Euler as early as 1783 who was fascinated by the magic squares of Chinese origin.
The Three Sudoku Rules
When you play Sudoku you will have a grid of nine rows and nine columns which is made out of smaller grids of three into three rows and columns. The three Sudoku rules that you should keep in mind are very simple to remember. The first is that the numbers 1 to 9 should appear only once in each column; the second is that these numbers (1-9) should appear only once in each row; and lastly the third one of the three Sudoku rules is that the numbers 1 to 9 should appear only once in each of the three by three grid.
There are two more Sudoku rules that were added later to the game by the Japanese newspaper, Nikoli. One says that the Sudoku puzzles should never have more than 32 clues to help in solving it; and the other says that each one of the puzzle should be symmetrical.
People seem to love the mind challenge Sudoku offers even more than the famously addictive Rubic cube. Its popularity among the masses worldwide forced programmers bring it on the computers and when it came out in the form of a computer program there were no more brakes to slow down the popularity and fame of this excellent mind game. As soon as the program hit the stores, it was an instant sell-out and as you can see from the numbers in sales its popularity is still growing.
Now, as long as you like the game and remember the three basic Sudoku rules you can enjoy playing this game for as long as you like.
