Can someone please explain to me how do you know what number to put in which square. Sometimes a number can go in more than one square. I can't figure this out! Help!!

Early in the puzzle, look at rows and columns three at a time. For instance, start with the top three rows. If any number appears twice in those three rows, you know that the other instance of that number must appear in the remaining row and square. This narrows down the possibilities for that number in that square to three, assuming that no numbers are already in those three cells.
Next, check the three columns that go through this square. If the number in question appears in them, it may be enough information to locate the number in the square you're working on.
Another line of attack is to look for a cell that has many different numbers in the row and column it's in. If the row and column a cell is in contain eight different numbers between them, you know that the cell must contain the one missing number.

Actually, no.
If you are playing with a traditonal 9 X 9 board, think of the fact that in each 3 X 3 portion, there will be a 1, 2, 3, 4, 5, 6, 7, 8, 9. Plus, in each row and column you will have one of each.
If you do a couple of simple criss cross and check each box, you will realize that there is a spot for each digit.
If you are new to the game, play a very easy one first and figure out the pattern before trying to take on the difficult ones. Most newspapers have easy ones on Mondays and harder ones as the week goes on. The New York Post has an easy one every day.

you have 9 numbers. 1-9. you try to put them in rows & columns without reapeating the horizontal or vertically.
