I have to disagree guys, I have won thousands in the past, although I very, rarely play them anymore. I do though, believe they track your winnings, have different difficulty settings for the software, and , can even be operated manually at times. You just have to know when to get out, and Dell Dude can probably verify everything I've just mentioned. My belief is, each casino, has a "set amount" they are willing, or allowed to "let" players win that specific day, and it is probably random. Therefore, some people may come in directly after someone has hit them big, and become victims of "payback time". Someone , or whoever is working the casino dept. that day or shift, keeps up with the status of profits and losses, and are allowed to randomly "let" a certain individual win, or lose, depending on that certain time of the day or weeks gains and losses. They claim they all use a "random generator" which has been tested exstensively, and that is probabl true, but at times, they kick that sucker up to a higher, more difficult level if needed..........My beliefs, anyhow.....
