I thought it was suppose to be a already made sudoku not a blank page and see if u could create one. It was i good thought

That isn't really the purpose at all. You are supposed to input a Sudoku puzzle from a newspaper, magazine, app or website in to this app and it will be solved for you.

Even though this kind of defeats the purpose of sudoku, (sorry, but it's true) this is a very helpful tool when you just cant solve a puzzle, or for beginners wanting to double check their results. The algorithm behind thismust ve complex, and i give huge props to the programmer.The only reason I didnt give this full score was that it was kind of cheating. Thats the only reason. Good job!

Thanks for recognizing the complexity of writing a program to solve a Sudoku puzzle, I think most people cant really appreciate this aspect. And I see what you mean that it is cheating, but this has mostly been a fun puzzle for me because it has been much harder to write than solving any single Sudoku out there.

Well, atleast it works. That's the important thing. If I did soduku's I'd use this to cheat, but it's nothing that I probably will ever use again.
