Sudoku Tutorials
There are a number of techniques for solving sudoku. They vary in complexity and ease of application but all have one thing in common - they aim to narrow the range of possible values in one or more of the cells in the sudoku. If, by applying the rules of sudoku, we can reduce the possible values in an empty cell to just one, we can enter that value in the cell, confident in the knowledge that it is correct.
The most common of these techniques are described on these pages. If you're new to sudoku, take a look at the beginners techniques then try some of our easy sudoku. More techniques for advanced players will be presented here soon.
