'It's a Sudoku' - Me.  'It's a trap!' - A. Ackbar Nick asked for it, and now you've got it: my Sudoku Solver that I cooked up with Visual Web Developer 2005 Express Edition, exposed as an ASP.NET 2.0 Web Service.  The link goes to an explanation of how to consume the service.  I also posted some sample code which you can download to consume the web service and solve a puzzle.  The sample code is a really simple Console Application which you can open with Visual C# 2005 Express Edition (or Visual Studio 2005 Standard / Professional / Team System)

I haven't had the chance to pretty this up.  Anyone care to write an Avalon front end? :)

Now, don't you all be cheatin' solving those four-by-four "Super Sudokus" from the Sunday Indo with this utility and making 150 yoyos a week for it :)
