Sudoku puzzles

[sysyphus]

Do all of them have a logical solution or do some require guesswork?

Can't say for sure, but I have yet to do any guesswork on a puzzle.

I can only imagine guessing would make things just harder becuase you might be wrong

Hmm . . . . . .

Funny that this should come up . My Computer Science project for the final year of my school ( 12th grade , for all you Americans ) is a program to solve these little puzzles . One of my assumptions for the prototype is that all moves are forced , and till now I've never come across a violation .

My paper doesn't have them. I enjoy the puzzles though. Does anyone know of a good free online source of these puzzles?

Awesome. That is exactly what I was looking for. Thanks a bunch.

I started doing them a few days ago, there are some easy things to do when you learn the tricks.
