how can someone finish a game in 0min 45 sec....is it possible?do you use a program or something? how many times do you roll the card

xthina check out fraug's youtube video on the "Am I cheating" thread to see how it's done. What fraug didn't include on the video is how many times he played that game before he made the video. It was probably quite a few. You have to play enough to memorize what card to play next.

so everybody is playing one game for 50 times until you learn the card and then you login just to have a high score...?

No they don't wait until they've played it 50 times (if it takes that long) before they login. Your allowed to play each game as many times as you want after you login and the game records only your best score. The time score is somewhat a test of who can click the fastest though it helps if you figure out the fastest way to get all the cards played. I think lowest moves usually draws more interest because it requires figuring out what the best options are. Both present their own challenges that makes the site uniquely fun (along with the friendly people we can chat with).
