Answer 1

Sudoku is a game with a grid.

The Grid is divided into 9 large squares.

Each of these 9 large squares is divided into 9 small squares.

The OBJECTIVE of the game is to fill the board with numbers from 1-9, BUT there are rules as to how you do this.

First Rule - Each Column can only contain one of each number from within the range 1-9.

Second Rule - Each Row can only contain one of each number within the range 1-9.

Third Rule - Each LARGE Square can only contain one of each number from 1-9

Hope this helps . . . that's the simplest I could think of explaining the game . . .

Answer 2

You can't duplicate numbers in any 9 square box, row or column. I usually start by looking for numbers that are used the most. Then find out where another one would do. I go rows, then columns. Then I pick a row and look for each number, if it's not in that row, I check the column and box. Sometimes you'll know exactly where it goes, sometimes you'll have a choice of a couple of spaces and can make notes in the corner with a pencil (that you can erase later). Do this with each number, in each row. Then I go to the columns and finally the squares. Then I start all over with rows. When I'm stuck, I'll try a number in a box and see if it works or if I end up with a problem and have to erase. Just keep up with what you're sure of (I use a pen for them) and what you're experimenting with.

Answer 3

Here is how I do it. Don't look at the whole puzzle all at once. Concentrate on each 3x3 square individually. Start with your first 3x3 square. Each row needs the numbers 1-9, each column needs the numbers 1-9 and each 3x3 square needs the numbers 1-9, all listed once in each. No repeats, so for example, if you already have 3 in one row, you know it can't be in that row again. SO....start with your first 3x3 square. Look at what numbers are in it. If there is no 1, start with 1. Look up and down every row and column that is part of that 3x3 square. Is 1 in any of them? If so, then you know 1 cannot go in that row or column of that 3x3 square. Process of elimination. See which blanks within the 3x3 square can possibly be 1 and pencil it into the corner of each possible blank square. Continue to do this with all numbers and move your way to the next 3x3 square. Eventually you will have enough filled in that you can go back and narrow down your selection of "possible " answers for each blank space.

Answer 4

Fill in the grid so that every row (<-->), every column (up, down), and every 3x3 box contains the digits 1 through 9.

Check out www.sudoku.com, there's a short explanation (see above) and tips on how to solve the number puzzle. There's one puzzle that they show you where to put which number and why. This should help you.

Answer 5

Use the numbers 1-9 to fill in every row, column, and "9-block" square. Do not repeat any of the numbers in the same row/column/block.

Start with simple ones to get used to it.
It's fun!

Answer 6

EACH COLUMN AND EACH ROWS HAS TO HAVE THE NUMBERS 1-9 AND EACH BOX HAS TO HAVE THE NUMBERS 1-9 AS WELL. YOUR CAN'T HAVE THE SAME NUMBER MORE THEN ONCE IN ANY ROW, COLUMN OR BOX. IT'S HARD AT FIRST BUT ONCE YOU PRACTICE IT'S ALOT OF FUN.

Answer 7

notice that each line has the numbers 1,2,3,4,5, and so on to 9 on it. that is how to correctly finish a sudoku. there are nine square boxes on a sudoku, these also have to have 1-9 in them. using this "formula" you can complete the sudoku and fill in all the boxes. i recommend trying easy sudokus to get the hang of it.
