how do you answer a Sudoku problem?

Answer 1

Carefully.
The trick is to think what the number can't be. Eventually, you rule out all the possibilities but the right one.
It's reverse logic.

How to Play Suduko
The Suduko puzzle most of the times is a 9×9 grid. This grid is made up of 3×3 sub grids with bolded borders called regions or blocks or boxes. So there are a total of eighty one square boxes that make the Suduko, some of these boxes contain numbers (the numbers most commonly used are 1-9) while most of them are eampty. The final goal of the game is to put a number in each cell so that each column, row, and region contains the numbers from one to nine (1–9) exactly once. So, each row, column and three by three region (block) should include all of the numbers from 1 to 9 and none of these numbers should appear more than once.

This is just the most common form of Suduko that you will come across, there are a lot of other variations where more than nine numbers are used or that the regions aren larger or smaller than 3x3 squares or are not even squares. However most of these variations are in most cases harder to solve and for more experienced users and they are not that easy to find.

As a matter of fact, you can find Suduko puzzles that instead of numbers are made from characters like symbols or letters. However, those are not that common. Numbers are mostly used for convenience reasons, any set of 9 symbols or special characters and letters can be used for creating a Suduko.

To sum up the rules of suduko:

Everyone of the rows must contain all the numbers from 1 to 9
Everyone of the columns must contain all the numbers from 1 to 9
Every 3x3 small square (region) must contain all the numbers from 1 to 9

Answer 3

There are many techniques, some of them pretty straightforward and others real complicated with names like swordfish, jellyfish, xwing and so on.

Answer 4

Buy the sudoku book 1 by the Telegraph. A huge chunk at the front tells you how.

Answer 5

You need only to understand that all the 9 rows of numbers from left to right and 9rows of numbers from top to bottom contains only one number form 1-9... and every block of square of 3x3squares also contains numbers 1-9 only, therefore there are 9 blocks of 3x3 squares which for convenient's sake it should help you better if you name them as A,B,C,D,E,F,G,H,I (written lightly in pencil at the centre of each individual block of 3x3 square).Alternatively, you can also high-light the individual block of 3x3 squares (altogether 9 big squares to be hig-lighted). That is to help you remember not to repeat any number from 1-9 in those individual 3x3 block of squares.
If you are a beginner, you need to be patient and go slow for a start....as you get along and enjoy the game, then you will take shorter time to solve them!
Happy Sudokuing....

Answer 6

I start by looking at each 3x3 square and work out where the numbers could go. I repeat this for the other 3x3 squares and then re-do this until I have the correct numbers in each of the boxes. It really is a process of elimination.

I also put a pencil mark in the corner of each box so I can work out where a number potentially fits and where it definitely doesn't go

Answer 7

Get a date with Carol Vorderman ansd ask her to do it for you. Then ask her to solve the Sudoku.

Answer 8

I start by putting all the numbers that could be in the box, and then I erase the ones it can't be.

Answer 9

I use all the given no's try and fill in any column or row with that no first.

Answer 10

Its just a process of elimination, its quite easy when you get the hang of it.
