Try to use logic to solve a Sudoku game. You know that you can't have the same number more than once in any row, column, or 3 by 3 box.
If you are solving an easy Sudoku game, the first thing you have to look for are definites. Definites are numbers that are definitely going to be there. Starting at 1, draw imaginary lines through boxes in that 1's row and/or column. When there is only one cell left in the 3 by 3 box, you know that is a definite.
Work all the way down through the numbers 1 to 9. Because you already filled in some numbers, this should help you get other numbers that had more than one possibility before you started.
If you get stuck in a Sudoku game, have a new look at everything and try to find a definite. This number is usually all you need to get going again. If you still can't find anything, start labeling every cell with every number that could possibly go there.
