Question

how do you do sudoku?

Answer 1

The big thing is to keep in mind that:

Each 3 X 3 box, row, and column CANNOT have two numbers the same.

Each 3 X 3 box, row, and column MUST have ALL of the numbers 1-9.

Start by looking at each 3X3 box. For each of the numbers 1-9, see if there is a single place that number MUST go.

Do the same for each row and column.

Each time you write a number in, see what it tells you about that box, row and column.

If you still don't have the puzzle solved then for each of the 81 "cells" write (small and in pencil) the numbers that MIGHT go there.

Now scan each 3X3 box, row, and column for "pairs" and "triplets". For example if 2 cells in a row can ONLY have 1 and 3 then while you don't know which one has the 1 and 3, you DO know that no other cell in that row can have a 1 or 3! You can then erase all OTHER 1's and 3's from that row.

There are LOTS of other techniques you can use, but this will will be enough for the easier ones.

Answer 3

the way to play sudoku is simple. All you have to do is make it so that you use 1-9 in every row column and box. You cant have the same number twice. Lets say that the row has a 1245678, you have to fit in the other numbers but they cant be the same as other numbers in the row, column, or box, you can also yahoo it or find sudoku for dummies.

How to Play Sudoku?

Sudoku requires no calculation or arithmetic skills. It is essentially a game of placing numbers in squares, using very simple rules of logic and deduction. It can be played by children and adults and the rules are simple to learn.
Sudoku Objective

The objective of the game is to fill all the blank squares in a game with the correct numbers. There are three very simple constraints to follow. In a 9 by 9 square Sudoku game:

* Every row of 9 numbers must include all digits 1 through 9 in any order
* Every column of 9 numbers must include all digits 1 through 9 in any order
* Every 3 by 3 subsection of the 9 by 9 square must include all digits 1 through 9

Similarly, smaller Sudoku puzzles, such as the 4x4 puzzle, must have the numerals 1 through 4 in each row, column and subsection. Larger Sudoku games (16 by 16) must have numerals 1 through 16 in each row, column and region. The principles are the same whatever the size of the game.

Every Sudoku games begins with a number of squares already filled in, and the difficulty of each game is largely a function of how many squares are filled in. The more squares that are known, the easier it is to figure out which numbers go in the open squares. As you fill in squares correctly, options for the remaining squares are narrowed and it becomes easier to fill them in. The Sudoku games on SudokuDaily.net let you check your progress as you go, to help prevent going down a wrong path.
Sudoku Solution Techniques

Sudoku PuzzleThe first things to do in tackling a Sudoku puzzle is to scan the rows and columns to see where a certain number might go, given the 3 constraints listed above. For example, the fact that a 7 is required in the top right corner can be determined by first analyzing its 9 square sub-region. The only numbers missing in the region are a 5 and a 7. However, putting a 5 in the top right box would conflict with the 5 already in the top row and the rightmost column. The 7, on the other hand, would not conflict with any of the given numbers.

Once the 7 is filled in, deduction requires that only a 5 can go beneath it as all digits from 1 through 9 must be represented in the region. From there, one can turn to the two remaining open boxes in the right column - these must include a 2 and a 4 as the column's digits must represent 1 through 9. One of these options, placing the 4 beneath the 1, would lead to a conflict with the 4 already in that horizontal row, so the only option for this box must be a 2.

However, options for boxes are often not that easy to deduce. Another technique is to "pencil in" possibilities and then follow the possible solutions that emerge until a conflict is found. Often these conflicts appear after 2 or 3 numbers are penciled in, and one can return to the start and try the next option until something clicks.

The Sudoku puzzles on SudokuDaily.net make penciling in options very easy. Just put a possible number in a box, click on it, and it is moved to the top left light blue area of the box. From there you can start considering possibilities until the solution to a box or two emerges, or until you need to pencil in another option and start again.

The great thing about Sudoku is that every step makes the next step easier by narrowing possibilities. Every solved box makes filling the next box a little bit easier.

Answer 5

You are given a 9x9 board and have to fill it in, using the numbers 1-9 only once:
a) per row
b) per column
c) per 3x3 box

Here's an example:
+---+---+---+
|963|174|258|
|178|325|649|
|254|689|731|
+---+---+---+
|821|437|596|
|496|852|317|
|735|961|824|
+---+---+---+
|589|713|462|
|317|246|985|
|642|598|173|
+---+---+---+

Answer 6

It's easy! It takes practice though, lots of practice. Okay, you see a box (3x3) and there are 9 of the 3x3. Example...http://www.sudoku.com/
Okay, horiztonal and verticle, there must be nummbers 1-9 and each box must have numbers 1-9. You try ro figure where the numbers are going to fit, without repeating a number twice.

Um...you can contact me with e-mail and I'll show you...Sudoku is a hobby of mine. Ah ha ha...whatever you do, don't call me a nerd...or ELSE! LOL! Jk...maybe. ;)

Answer 8

yup everyone else pretty much nailed it. but just be observant of every number in every column and row, and use a pencil! youll be fine

Answer 9

justby logical reasoning and elimination you keep filling in the blanks

Answer 10

make sure no # is in the same spot, also, the book should tell you and help you, too
