Apart from these the Sudoku player forums discusses excellent suggestions and methods for solving challenging puzzles. And if you want a free puzzle generator application then Simple Sudoku is great.

I was just looking for the puzzles in a text format to rip it out to try it with my solver that I am working on. Just too lazy to type in puzzles into it.

Basically, you have a 9x9 grid that is made up of 9 3x3 grids. Some of the cells will have a digit in them to start. When you finish, each row of the 9x9 grid will contain the digits 1-9, and each column will contain the digits 1-9. In addition, each 3x3 grid will contain the digits 1-9.

That's it.

Sounds like a good thread for Programming Diversions -- create a Sudoku solver.
