   you really have to get the boxes. and also, always find out which numbers are missing then like figure out which numbers go where… =]

   good lucckkk! =]]

   I can’t do it. I guess it just depends on how your brain works.

   go to the back of the book and look up the answers

   but for real advice i always start with the row that is missing one number and just work from there, use pencil and keep checking to make sure your not messin up

   go through each box and write it’s possibilities

   just keep narrowing it down from there you’ll eventually get it.

   the only strategy is not focus on 1 box, try to do the whole boxes together!

   Many, many people find Su Doku hard. I find it perplexing too.
   Some strategies are to put more than one number, in only one box, and then figure it out at the end…
   Example: If one box could have 7 and 2, you could write lightly in the box “7/2″ or even 3 numbers, you could write “7/2/4″

   Thank you

   I find them incredibly easy, are u looking cross wises and down the rows for the numbers… anyway practice make perfect!

   You are right it is easy once you work out the formula. Just do it line by line to start going down, then across, then do the boxes. That’s the way I do it.

   sorry if this doesn’t make any sense : P but try to put the numbers in a crosshair and find if there are any numbers in the vertical column and then look in a horizontal row and finally look in the box to seeif any of the same numbers are there.
   hope i helped a little.

    Keep at it. I used to be like that too but after a while your brain kinda gets the hang of it.

    It took me a little while to get it too. When I get started I look at all the boxes, rows, and columns (separately of course) and then I see what numbers are missing and I try to fill in all the possible numbers for each box. If I can find a box that only has one or two possibilities I start working there. After you get started it all just starts flowing. Hope I helped. Good Luck!!!

    Hi Flowergirl

    First get the ones that are obvious. Then you’ll find you get a number in this column, and then a number in a whole other row. You need to keep changing the way you work on it from number to number but by and large, it’s like a knot – once you start untangling it, the rest will follow.

    The “box” strategy won’t work. It’s the kind of puzzle you have to work on as a whole – this column, that row, that box. When you try to solve it one box at a time, you’ll hit a brick wall.

    Cheers ~ Peps

    It’s very hard, but you can sort it. Start from the box with more numbers, and remember that you cannot have the same number two times in a row, a column or a square. So, narrow the possibility to two-three numbers, writing them in the corners of the little square in which you place numbers. When you find a place where is more possible to find one of those numbers, delete it. Then you’ll narrow more

    The puzzles themselves are designed with different degrees of difficulty. best to practice technique etc. on the more simple ones first. It is all logic. No mathematical knowledge is needed. A lot depends on how organised and methodical your mind is.

    start with the number that is on the card the most then check each square that it is missing from and line up up and down because if it is already in the line then it cant go there then it will point out where it can go.
    then pick the next number and do the same,
    also each box of 9 must contain every number
    and across all the lines up or down must have all the numbers.

    Soduko is a challenging numerical puzzle. Once you get my formula for completing the puzzle, you will not have problems solving them anymore.
    You use numbers 1 thru 9 across each line, vertically up and down each line and within each box of 9 numbers.
    You look for a column, row or box with the most numbers found in them and then figure which numbers have already been used and what numbers are left to be used then. For example: sometimes you will find a vertical line using numbers 1,2,3,5,6 and 8 and then you need to use the numbers 4,7 and 9 in the remaining boxes. So, then you will look at the horizontal line of numbers used and they have numbers 1,2,3,4,6 and 9 and you need 5,7 and 8. Therefore, the missing number will be the number 7 because that is the matching number among the missing numbers for that square. (4,7,9 and 5,7,8 were the numbers that had not been used yet vertically and horizontally respectively and 7 can be found in both sets of numbers.)
    At the same time, you can also look at the numbers that have been used and have not been used in each of the square boxes and use the same method within the box of numbers used and not used yet and then filling in each single box with a number that has not been used yet in that square. Make sure to look vertically and horizontally at the same time as looking in the square box.
    Take each line and square box at a time. Don’t look at the whole puzzle and try to solve it.
