> In general, there is only one hex known to be clear at any given time. This means that the structure of the game is that you mindlessly reveal whichever tile you just gained information about rather than suffering under any obligation to think about what you can tell from the board.

That is not remotely an accurate description of Hexcells. Either you didn't play it, or you didn't play it more than the early levels. In Hexcells, you do not just have info on the tiles, but also along rows of hexes (telling you how many are in that row, and sometimes if they are contiguous or separate), as well as some hexes which tell you how many tiles you need to flag in a radius around them. It is fairly common that you need to combine multiple pieces of information about the board state in order to deduce what the next move is, with some of the later puzzles being so complicated at points that you practically have to bust out pencil and paper to work through the logic.

And all of that, while interesting, is not the improvement of Hexcells over Minesweeper (nor are the hexagon cells). The improvement is that you never, ever have to guess blindly and have the game tell you if you were wrong. Every puzzle can be worked out through sheer logic, though some do require you to guess at a hypothesis and then do a long chain of logic to prove or disprove if that would be a valid move (kind of like sudoku puzzles often do). The expanded mechanics are interesting too, but just the fact that you don't ever have to guess blindly is a massive improvement.
