Right. But that still isn't enough for minesweeper, where a cell can be: covered, marked, uncovered with no mines next to it, uncovered with one mine next to it, uncovered with two mines next to it… etc until uncovered with eight mines next to it.
So except if you limit the game to having no cells with more then one neighbors with a mine, it won't work.
