Hi
I've been making a program for people to solve Sudokus in, but want to add a generator that can make 9x9 Sudokus of a few different grades (Easy, Medium etc). All I want is to parse the difficulty to a sub or method, and have it output two DataTables (one with the Sudoku to solve, the other with the answers - or maybe just one that is 9x18, I can do code to separate it).

I have tried playing around with this generator but can't seem to make it work - does this generator make the actual Sudoku to solve or just the answers?

I have also tried this generator - using the method Generate in the SudokuModel library - which I think might be better to use, but I can't get that to work either (haven't been able to work out what a Tuple is even after looking up MSDN).

If someone could please help me find a suitable generator, it would be greatly appreciated, as I don't know very much about algorithms for generating Sudokus.

Try www.setbb.com/sudoku which has a forum with detailed discussions on approaches/algorithms for sudoku generators. I also hope to shortly post an article/code for a sudoku solver/generator in vb2005...
