Thom27: I like the Windows Messenger-style of Minesweeper. Just shoot and get one point per mine shot. If you shoot a mine, shoot again. (That would make a total different game though)

For Frog Legs it is better to hide the guesses. The version on jijbent.nl http://www.jijbent.nl/java/mijnenveger/index.php (Warning, it's Dutch!) states the guesses are secret which makes it a better game I think. Also there are some more mines added (15 instead of 9). Maybe Frog Legs can be improved so to make it a better game.
