I had excellent luck, noticed my waitress liked to play them, bought one and gave it to her as a tip. She won and asked me to buy more with the winnings, they won more than face value. Did that twice and same result. She bought my dinner and I got lucky.... I mean, I was fortunate...
That's my only experience with them. And it was good!
