In minesweeper online there's also a "no guessing" mode which, in my opinion, is much more interesting than the normal mode. It means that if you guess in a situation where you could have deduced the mines, you always get a mine. Conversely, if you really are in a guessing situation, you will never get a mine. I'm pretty sure the game calculates the unknown part of the map after each click anew.
