I am waiting to read if any of them did or were they near enough as well to getting the casinos wiped off and did, they finally got the payment or not. Its really interesting though hardly people could reach to that level as suggested rightly that casinos have the edge and either your lucky in the world to win it else it does not generally happens.
One of the other threads has posted information on high rollers and their winnings. From what I could see if someone walks into a Casino and starts winning, they are quickly given a shake down and sent on their way. Even if you had a magic wand and couldn't loose, you would have to do so slowly otherwise the blue light taxi will be on its way.
