I prefer to use the process of elimination to solve Sudoku. This leads me to my first of several Sudoku tips and that is pencil in all the possible candidates for each cell, row, column, and region.

Some Sudoku computer programs have the option to show you all the possible candidates. Some online puzzles allow you to pencil in your candidates.

In the example to the left, you can see the naked single is the nine. All the other nines may be crossed off leaving a 6,8 pair, 6,7 pair, a single 7, and a 4,6,8 triple.
