Sudoku Fever

I jumped on the bandwagon and created my own Sudoku game. Made it with Shockwave. There are a lot of other ones out there, but mine is one of the few to generate random puzzles, thanks to the fast speed of Lingo. Most (all?) Flash-based Sudoku games are one-a-day games. I assume that is because the puzzle grid is pulled from an external source out of a database, and not generated by ActionScript.
My method for creating the puzzles follows some of the techniques used by others, but also have a few things I came up with on my own. I find it creates relatively challenging puzzles. Some start off very easy, and then you hit a brick wall and need to use some more advanced tehcniques to finish.
