Ive done nothing. where I grew up in queens, I had 2 friends who ventured off into the casino industry back in the late 70s. One I lost touch with, one I stayed in touch with. I had another friend of my bil and sil that became an attorney and worked on the legal staff of a casino, one which no way will I mention. I spoke with them time to time. Interesting stuff. What I always took from my Pit Boss/now retired queens friend(vegas for 15 years, then moved on to another casino), any equipment that malfunctions off the normal expected results of that equipment can be a devastating loss for any casino. It doesn't take long for any equipment that fails to produce accurate results to be exploited by saavy gamblers. why should dice be any different. Bad dice lose that randomness, the casino loses its built in edge. They designed the game around the total randomness of dice rolls. They design tables around the same expectation of randomness of dice rolls. Bad dice can only hurt them in the long run. First, if sevens just keep turning up every other roll, saavy players will jump on it. Even me, the most stubborn right player has gone dark when I see nothing but sevens on a cruddy day. Second, right players will get frustrated and leave. And may not come back. That is very bad for business, not to mention so many people blasting their casino online further hurting business. casinos wont make money without people inside gambling.
