Question

how do you do sudoku i swear i dont no how

Answer 1

There are actually instructions on the Sudoku game on how to play it, but I can give you a quick explanation here.

The easy level of the Sudoku game has 4 symbols - Heart, Pot of Gold, Rainbow and Green Clover. When you launch the game some of the squares will have symbols in them and some are blank. Your job is to fill in the blanks with the correct symbol. The board is divided into 4 blocks each is 2 squares high by 2 squares wide.

But here's the tricky part...you cannot have the same symbol in any row, any column or is any of the 2X2 Blocks. Let's take this as an example:

Heart=1
Pot of Gold=2
Rainbow=3
Clover=4
B=Blank Square

Your starting board might look like this:

1 2 | B 4
B B | 2 B
-------------
3 B | 1 B
B 1 | 4 B

Starting with the first row across you can see that there is only one thing missing - a 3 (Rainbow) so lets fill that in.

1 2 | 3 4
B B | 2 B
-------------
3 B | 1 B
B 1 | 4 B

In the second row you are missing 3 symbols. If you look at the upper left square you can see that it has a 1 (Heart) and a 2 (Pot of Gold) but no 3 (Rainbow) or 4 (Clover) so you know that the two blanks must be a 3 and a 4 but the question is which is which? Since you can't tell move on to something else. The third row is also missing 2 symbols and you can tell that it's a 2 and a 4 but again, you can't be sure which is why just by looking at that row. The same problem exists in the 4th row and in all the columns.

So next we try the 'squares'. Let's look at the upper right square. That has a 2, 3, and 4 but no 1 so obviously a 1 belongs there.

1 2 | 3 4
B B | 2 1
-------------
3 B | 1 B
B 1 | 4 B

Here comes the tricky part - you now have to look at rows and columns and squares together to solve the rest of the puzzle. The first column contains a 1 and a 3 so it is missing a 2 and a 4. The first square contains a 1 and a 2 so it is missing a 3 and a 4. If you were to fill in a 3 in the Column 1 blank spot in the 1st square that would give you two 3s in that column. So that means it must be a 4.

1 2 | 3 4
4 B | 2 1
-------------
3 B | 1 B
B 1 | 4 B

Which means that now you are missing only a 2 in column 1 and a 3 in square 1. Filling those in gives us this.

1 2 | 3 4
4 3 | 2 1
-------------
3 B | 1 B
2 1 | 4 B

From there the rest should be easy. Row 4 gets a 3
1 2 | 3 4
4 3 | 2 1
-------------
3 B | 1 B
2 1 | 4 3

Column 4 gets a 2
1 2 | 3 4
4 3 | 2 1
-------------
3 B | 1 2
2 1 | 4 3

And Column 2/Row 3 gets a 4
1 2 | 3 4
4 3 | 2 1
-------------
3 4 | 1 2
2 1 | 4 3

And there is your completed grid. Note how each 2x2 square, each row and each column contians only 1 of each number (symbol)

Answer 2

Sudoku rules are extremely easy: Fill all empty squares so that the numbers 1 to 9 appear once in each row, and column and you have to make sure it appears only once in each 3x3 box.
