Online sudoku solver
This is an online sudoku solver, ive not quite finished implementing this yet so the input error checking isnt really very descriptive. Expect some changes soon. I originally made this to generate the solution to project euler problem 96.
I've recently converted the front end code to use Adodbe Flex - so this is now an Adobe Flex Sudoku Solver with a PHP back to it - this means i can do nice client side validation much more easily.
Most sudoku problems need at least 17 clues to generate a unique solution. My code will still generate solutions for problems with less than 17 clues however the solutions obviously wont be unique. The application will solve all problems, however i have implemented a 10 second timeout to prevent excessive server load.
While its quite efficient there is a great deal of scope to improve the code - I'll do this at some point in the future. I'll also add a function to generate the sudoku puzzles. In the mean time if your looking for a PHP generator you could try this PHP sudoku generator

My sourcecode for the old HTML/PHP sudoku solver can be downloaded here
How easy would it be to extend this to 4×4 grids?
Shouldn’t be too hard to do – i’ll see what I can throw together at the weekend so watch this space – In theory all you need to do is set a new range and set the boundaries for each “sub-square”.
So whats the word on the 4×4 solver?
Been dragged away doing other things at the moment, hope to have something done in the next few weeks,
