Why are my solution and the solution found by solution-sudoku different?

Some sudoku puzzles have more than one solution. Solution-Sudoku gives you an answer that is always 100% correct but cannot give you every possible solution if your puzzle has more than one.

Is this really free?

Totally, 100% free. The freely available software you can download on this site does not contain any spyware or adware and is fully functionnal. The web site is entirely supported by the non intrusive ads you can see on our pages.

Who is behind Solution-Sudoku.com ?

My name is Julien Adam, I am a software engineer and trainer working for a small IT services company in Paris. My areas of expertise revolve around Microsoft technologies and more specifically Microsoft .NET.

I built this site for fun in my spare time (which means my company has nothing to do with it). Its only goals are to provide a free service and to demonstrate what can be done with the technologies I work with. I hope you enjoy using it as much as I did creating it!
