Starting Sudoku
It’s only yesterday that I played Sudoku, found some puzzles at the Tunisian La Presse Magazine (probably picked from another magazine), and it seems that I liked the game. As the 8 puzzles were not enough for me, I’m thinking about making a Sudoku generator; why not with PHP: random puzzles and you can fill them online, etc.
However, I’m worrying about legal issues. What should I do? Whom must I ask for permission?
Anyway, it is worth to try developing an algorithm.

Wikipedia has a sudoku article that touches on ownership and copyright:
http://en.wikipedia.org/wiki/Sudoku
It appears that anyone is free to publish their own sudoku puzzles, but the a company called Nikoli has the name “sudoku” trademarked in Japan.
If you are looking for more puzzles to solve, this site publishes five new puzzles every day, plus hundreds more in the archive:

Thanks, Kristin for the links.
That would encourage me to develop on sudoku!

I fell in love with Sudoku quite recently too, and in my last trip to London I bought a little handbook with about 70 sudoku puzzles in it. It’s such a cool game
If you do develop a script that generates puzzles, please do share with us. And if you need any help, I’d be happy to do that

Thanks MMM! I will start to develop classes, it’s a tricky algorithm but I found some Perl implementations that I can “translate”
I just wanted to mention that I am more crazy than you!
Only 70?? I wrote a script that downloads daily sudoku’s from archives, converts them to PNG, crops the images and join more than 10 puzzles into an A4 paper to be printed
