How to Solve Sudoku

Sudoku has recently conquered the world by storm and is now one of the most addictive games known to keep the mind sharp perfect! When compared with the first Sudoku puzzle can be found a little 'intimidating to see the numbers, a white screen for a few more, but Sudoku is easy and satisfying when you have an idea of mystery to solve this problem.

First of all, is a Sudoku grid in the Rule 9 of 9 squares or to alleviate, 9 large boxes of 9 small squares. EachNumber from 1 to 9 must function only once in each field and once in each row.

Take the first 3 rows of a Sudoku grid. Say the first line and second line, both have a number of 4 "You know, the last number is 4 for the bottom line. Sometimes there are more than one place a number could then proceed to apply the logic to determine whether go. It 'best to start with simple puzzles to Sudoku, for the hanging of them and progress in the medium and hard.

One waydoing sudoku, although not everyone uses this approach, is to lightly pencil in possible numbers in the corner of each square, so when one is ruled out as having another number belong there, you know for sure that it goes in the other box.

If you have only a couple of cells left in a row or box, it is worth checking to see if you can fill one (then it is obvious what goes into the other square) by seeing which number has to fit there.

If you have a row or column with 8 numbers filled in, you know what the missing number has to be, since the numbers 1 to 9 must appear once each in each row, column and box. Filling this in might give you other clues to what other squares might be.

If you get stuck, I suggest going through the whole grid and putting possible numbers lightly in pencil in each square until you come up with something. If you have a row with 3 squares free and the first could be 2 or 4, the second could be 4 only and the third could be 2 or 5, you can work out from that that the second square has to be 4 (since it is the only one that fits), the first box must be 2 (since 4 has been taken) which leaves 5 to go in the third box. This is a logical yet simple approach.

As you play more sudoku, you will come up with your own way of playing and your preferred method, whether it is more to do with elimination or logic or a mixture of both techniques, depending on the skill level of the sudoku game you are playing and what works best for you.
