Answer 2

OMG i am like the sudoku addict i love doing the ones that are four by four now...they're huge and very challenging...but how to solve a 3X3: the rules are you must complete the puzzle by putting a number into each square, and in the end it must turn out to every row, column, and 3X3 square having the numbers 1-9 in them, right? well, this means that one number can't be in the same square, row, or column. so you can start with any number that you want...say you want to start with a 7. so you look for all of the 7s in the puzzle. You then use those 7s to elimenate where another 7 can go...a bit confusing, huh...ok...then let me draw it out.


so if this is the puzzle:
_ _ 7 _ 4 1 _3_

3_ _ _ _ 8 9 _ 2

8 5 2 9 _ _ _ _ _



_ 8 3 _ 2 9 _ _ 6

5 _ _ 4 _ 7 _ _ 1

1 _ _ _ 6 _ 2 7 _



_ _ _ _ _ 2 6 1 3

9 _ 8 6 _ _ _ _ 4

_ 6 _ 3 7 _ 5 _ _


the _ mean thats where to fill in a #, and the big spaces show where the squares are. Ok, so if you look for all the 7s, you'll see that there are four. if you count left to right and you count the 3X3 squares, you will see that there are two 7s, one square next to the other in squares 5 & 6. you also see that there is a 7 in the first square...so you should now see that the square under the first box has no 7. but it does have 3 squares, each with 7s in them, around the box. if you take the 7 in the first box, you will notice that it is the 3rd number in the first row. you will also notice that in the box below it, there are two blanks, one in the 3rd number spot for the 5th row, and the other in the 3rd number spot for the 5th row. so now you know that neither of these blanks can be 7s, as there is already a seven in the column (remember, 1-9 in each square, row, and box...if there is more than one 7 in the column, then the puzzle would be wrong). you now notice the two 7s in the boxes to the right of the 4th box (counting right to left)...you use them now....you notice that there is a 7 in the 2nd row of the 5th box, so you see that there are two blanks in the 4th box, but they cant hold 7s because there is already a 7 in that row. same thing for the 7 in the next box. so now you know that the 7 has to go in the first blank of the 4th box. you now have to finish the puzzle. once you get better, you will find loopholes, but they will be confusing if you don't know how to sudoku yet. hope that this has helped you...it might be a bit confusing...srry...i tried...its hard to teach sudoku via yahoo answers PS the thing i just showed you is elimination

Answer 3

It is a bit difficult to explain the various techniques used in solving a sudoku puzzle. You would be aware that there are hundreds of books on sudoku, and most of them contain suggestions. There are also a number of websites that would help you. I found the tutorial in www.sudoku.com.au to be good.

You need to try solving the puzzles by yourself, starting with the easy ones first, instead of learning from a book or website. This is not at all a short cut- you need patience and perseverance. You could evolve your own special methods as you go along. This is what I did and it has helped me in my attempts better than reading a book on solution techniques.

Answer 4

You need to get the numbers
1 to 9 across, up and down,
and in each 3x3 square.
You can't duplicate a number
in any line, or the 3x3 box.

Hint: Start with the puzzles that
are marked Easy. Then work your
way up to Medium and Hard.
The puzzle requires logic and
elimination.
Example: if a 4 is in the 3x3 box,
then, 4 can't be in any vertical or
horizonal lines that extend from that
box.
That would duplicate the number.

Good luck.

Answer 5

You are given a box of squares and the numbers 1-9 you have to put the numbers in the squares so that no one number is in a line,horizontal,vertical, or diagonal more than once. You have to besure the squares only include the numbers 1-9 only once. So no square or line in any way has the same number more than one time. Hope you can get this.

Answer 6

My solution? Rip it into shreds. Sure, that's not how the makers intend on you "solving" the puzzle, but it saves you from hours of frustration and shows the puzzle who is boss.

Answer 7

You simply find a number to go in each box containing 1-9
