blarth: It's much better than minesweeper. Only one style of clue used to give you information matches what minesweeper does, but information is given in many other ways as well. Trying to figure out how to put all the clues together makes it way more enjoyable than minesweeper. The fact that you can always complete the puzzles without guessing is also a big plus for the game. The fact that it looks nicer doesn't hurt either. :)
Edit: I have an extra steam key for hexcells+ if someone else is interested.
It looks interesting. May I ask for your extra copy?
