I managed a 6 sec beginner level, a gov job, where we had a minesweeper tournament (I won)
On this computer 87 inter, and 797 expert.
Given enough time to play, I can easily beat any of those scores. My best expert level was 120-ish seconds, but that was after about many, many games. I win on expert about every hundred games or so. The first 30 flags are easy. The next 30 are more difficult, but I can get them every ten or so games. The next 30 are very tough (about every thirty games or so), and the last 9 flags are what ends up killing you almost every time.
Intermediate is easy, I can beat it in about 40-50 seconds about every five games. And I have to really screw up to lose on easy.
Of course, as I said, I've had LOTS of practice. It's a matter of getting a good starting position (so you lose about two-thirds of the games by your initial frantic "clear a big enough gap to start from" clicking), then you have to recognize the common simple patterns (the rarer or more complicated patterns, I'm not so good at), then making wild-arse-guesses to break out of jams (especially at the end, when you've nothing to base a guess on...).
A fun game. I've spent thousands of dollars on computer games over the last twenty years, and the one game I love the most comes free on every computer I've bought...
