Why bother solving a Sudoku puzzle with a software program?
What brain power does it take to do that? Writing the program - yes. But just for a solution - no.
The whole point of a puzzle is to challenge the mind and gain the satisfaction from the final solution.

There are three tutorials here;

1.   a very simple puzzle to start with,
2.   one for a puzzle in The Daily Telegraph and
3.   one for a puzzle in The Times.

First, a very simple, animated tutorial of my own composition to explain the basics of sudoku.

Second, a 24 page tutorial charts the progress to a solution of a Sudoku puzzle from the Daily Telegraph rated as having a moderate level of difficulty.
At each step there is a brief description of my reasoning.
My thanks and recognition to Michael Mepham of The Daily Telegraph who set this puzzle on the 23rd. March 2005. This puzzle requires a guess at one point just to spice things up!

The third tutorial takes seven pages to work through a 'fiendish' rated puzzle from The Times
published on the 1st. April 2005. My thanks and recognition to The Times and Wayne Gould.

I readily admit that there may be more elegant solutions to these examples. This is just the way I did it.
