Forgive my ignorance, but is there any other way to do a Sudoku puzzle than by elimination? Also, this method will work regardless of difficulty level.

Yeah, I do something similar where I write in all possible numbers that could go into the empty boxes. Of course, for Sudoku to be a proper challenge the idea is to write no extra numbers, but the one you think is right. Keep it all in the head.

While agreeing that there’s never any need to guess in Sudoku, the logic is generally so simple that you don’t need to go through all this palaver. And doesn’t this purely mechanical procedure take all the fun out of it? Anyway I’ve given up Sudoku and only bother with Killer Sudoku as in the Times. That at least has some maths in it.

J — you’re forgiven, of course ;) but this method by itself won’t solve a difficult sudoku puzzle which requires a certain amount of forward thinking. There’s a slightly irritable conversation going on under the link I gave on this very subject.

“this method by itself won’t solve a difficult sudoku puzzle”

I agree in the sense that it doesn’t address situations where elimination occurs because spaces within a given block or line have to be certain numbers/letters, but I still consider that elimination, albeit with some forward thinking.

Hi, people! I have some interesting facts for you :) Anyone know that sudoku was created by an architect? The modern Sudoku was designed anonymously by Howard Garns, a 74-year-old retired architect and freelance puzzle constructor, and first published in 1979. One more: I heard that my favorite game - the popular puzzle game of Sudoku is brought to the next generation of consoles. Go! Suduko 2 has evolved from the original game to provide a variety of new features and game modes. :)

Thanks, Kevin
