'Sudoku', sometimes known as 'Nine Numbers' is one of the most popular and most infuriatingly addictive puzzles. It is played every day by millions of people all over the world, but "How on earth do you solve them?" This article attempts to shed some light on how to solve this simple, but tricky logic puzzle.
Although on the surface Sudoku looks like a numbers game, the puzzle is actually solved using logical skills.
It is a puzzle played on a 9 x 9 grid divided into nine equal squares. The objective of the puzzle is to place the numbers from 1 to 9 in the grid. Each number must appear only once in every row and column, and in 3 x 3 squares.
A Sudoku puzzle game begins with a set of numbers already placed in the puzzle. These are called 'Given Numbers'. The 'Given Numbers' determine the level of complexity of the puzzle, and where they're placed. The puzzle can be simple or very difficult. If you haven't tried solving a Sudoku puzzle yet, I suggested that you begin with an easy one first.
When you buy a puzzle book, the different levels are shown as easy, moderately hard or very difficult. Most newspapers print Sudoku puzzle games. Many of them publish the easier ones on Mondays and Tuesdays, and as the week progresses they get more difficult.
Over the past few years, Sudoku has gained immense popularity throughout the world. If you often play the game, then you have probably have an idea why the game is so addictive and fun to play. If you haven’t played the game yet you should definitely try it.
The first thing that came into most peoples minds´when the think of Sudoku is mathematics. Sudoku has nothing to do with addition, multiplication, subtraction and division. Sudoku doesn’t require such skills. The game is totally about logic.
Sudoku puzzles require logical reasoning. The concept of Sudoku is very simple. You basically need to fill up a 9x9 block of squares. Each puzzle can contain one or more blocks and every column and row should contain a number ranging from 1 to 9. The easiest way to understand is maybe to check and browse on through online sites wherein there are posted ideas and information of the game’s basics.
For beginners, here are some helpful steps for solving the easy Sudoku. Follow each step carefully and you will have a better chance of solving the puzzle.
1. Think carefully and cleverly. As you already know, you cannot have two numbers the same in each row, column or 3 x 3 boxes. You can use this to get other numbers in the series. Remember the more difficult the Sudoku is, the less chance you have of starting the game easily.
2. In solving an easy Sudoku, the first thing you must keep in mind is to look for the 'possibilities'. 'Possibilities' are the numbers that are possible. Beginning at 1, make an imaginary line on the boxes in the 1's row and column. When only one box is left in the nine-square block, you will know that it is a 'Possibility'.
3. Carefully work through the numbers until the number 9. Since you have already placed some of the numbers, this will help you work out other numbers, which have more possibilities.
4. If you are trapped, go back and look at the other numbers. You are sure to have missed something on the puzzle. When you find it that is where you start again. If in the process you still cannot find the "missing number", begin by labeling each block with every number that has the possibility to be in the box.
The Basic Technique for Solving an Easy Sudoku.
The basic technique most players use when trying to solve an easy Sudoku, is to go through every number, trying to place as many numbers as the puzzle permits. You have to observe the numbers on the rows and columns to make sure that there are no duplicate numbers present.
If you are working your way through the numbers 1 to 9, be sure to go through the same process again. Then, look at the squares to find the numbers you can use to prevent other numbers from filling in.
Try to train your mind to look at the numbers in all 3 x 3 boxes, columns or rows. In this way, you can easily spot the missing numbers you need in each 3 x 3 boxes, columns or rows.
Finally, if it is your first attempt at solving a Sudoku puzzle, be patient. It may be an easy Sudoku but it may not be as simple as you think. It requires great logical skills and careful thinking in order to complete the puzzle.
