How to start solving a Sudoku puzzle? The following steps will help a player to solve any sudoku easy or difficult.
Easy Sudoku
1. be careful while solving the puzzle. Now that you already know duplication of numbers isn’t allowed, you can use it as a hint for considering other numbers. Always remember, more difficult the given Sudoku, harder it will be to start.
2. While solving any easy Sudoku, you should first prioritize your search for possibilities. They are the numbers which are possible in the column, row or block. So if you know the possible numbers, it will be easier to choose whichever number is suitable for a particular cell.
3. Start your work from number one till you are on your way towards number nine. Since you already filled in some numbers, this will be your clue to search for other numbers to be filled.
4. If you become confused, you can go back and make sure to have a look at every number you have filled in already. This will surely help you to know if there is any number you have missed. Once everything gets settled, you can go on with the puzzle and try to complete it. If you still can’t find the problem, label each three x three box with numbers which can possibly go into the box. Example, if an empty box is left. Fill it with possible numbers to see the result of your action.
5. It is advisable to begin your play in a magazine or newspaper. There are magazines or newspapers, which have sudoku. Easy puzzles usually come out during either Monday or Tuesday. The difficult ones come out the days that follow.
Hard Sudoku
1. Start with number 1. Use the same logic used by you in the easy version to complete every empty block, column and row with all possible numbers. Put possibilities if necessary. They’ll help you at a later stage if you have 2 or 3 choices for each cell but can’t remember them all.
2. If two cells in any row, column or block is one of the two numbers, remove the other possibilities using it. Example, if in a three x three block, four empty cells are there, you have established: cell A and cell B can be one, two, three, four; cell C and cell D can be three or four, you’ll know cell A and cell B can never have three or four as they already have one or two. Cell C and cell D should be three or four. This information can be quite helpful to complete other boxes given.
3. A hard Sudoku will consume more time. It can even take few days to complete, but they can provide players more fun, contentment and enjoyment after they have solved the puzzle. It is just the same as an easy Sudoku – both of them will give you very less clues to start with. The best technique of solving the hard version is to know the possible digits which can go into each box. In case you have two numbers for a single 3 x 3 box, column or row, decide which number should fill each of the locations. Though this may be confusing, when you apply it, you’ll realize that it is simple and quite useful.
4. Visit the net. There are lots of sites that provide puzzles – easy to hard. Practice some of the sample puzzles and prepare for a more complicated puzzle.
Follow these steps to solve the Sudoku and find out that however difficult it may seem, in the end, you will feel incomparably excited and have fun.

The Puzzling World Of Sudoku Puzzles
Sudoku puzzles are the newest puzzle craze currently sweeping across many parts of the United States. The game has only one basic rule, that is, every row and every column on a 3 by 3 box of Sudoku puzzles has to contain the numbers 1 through 9, but only once with no one digit repeating itself.
Sudoku puzzles, also referred to as Number Place in the United States, are said to be deceptively simple, since a player can start the game quite easily only to find himself later on getting stuck in the middle of the game with no clear puzzle solution in sight.
Good Sudoku puzzles ideally should ultimately have only one solution, using only one’s logic skills, meaning guesswork is not an effective method in solving the puzzle.
However, solving Sudoku puzzles on pure logic alone can prove to be a difficult task. For logic to be effective, a puzzle should be able to move progressively. This simply means that at every stage in the solution of the puzzle, there must be at least one square or block whose value can be determined easily. Determining that one value should then uncover at least one other fully determined value, and so on and so forth. Yet, this process can best be achieved by applying guesswork. By making a speculative or guessed entry in one block, a player can eventually determine if the other block has a logical entry or maybe none at all. This can be quite confusing, but the implication here is that while Sudoku claims that it can be solved by logic alone, it is not a good starting option. A player has to first make a guess or even guesses on his or her initial entry.
While Sudoku puzzles appear to continue boggling the minds of many puzzle addicts, it is interesting to note how the puzzle can be solved with relative ease by many computer programs. The question of logic and guesswork again comes into play in this particular aspect because most computer softwares are often programmed to make use of the trial-and-error concept, making quick corrections when an errant entry is made in a particular square or block.
Playing against a computer in a game involving Sudoku puzzles thus tends to be a futile endeavor. Your opponent can easily make the necessary corrections, using purely trial-and-error, and ultimately finding the right solution. You, on the other hand, are stuck in logical thinking, trying to justify the entry of a particular digit in a particular square or block.
Nevertheless, the beauty of Sudoku puzzles is that while the rules involved are quite simple, they do not necessarily solve the puzzle by themselves alone. The game also requires the application of a certain degree of analytical method that is not entirely written in black and white, but often can be discovered only by mere guesswork. A few of these in fact have been given interesting names such as “swordfish” and “x-wing”. In this regard, it is no great wonder that Sudoku puzzles have become a popular pastime in many parts of the world.
