About the Bellagio incident: I ran into trouble there because the table crew said my throw was not legal because the dice didn't bounce off the back wall far enough. They said if I set my dice (which was okay) my dice had to bounce off the back wall by a number of inches. My dice hit the back wall but came to rest against the back wall.
That prompted me to call the Gaming Commission and the NGC told me their rule:
1. Dice must fly in the air
2. Dice must bounce off the table surface at least once
3. Dice must hit the back wall
There is no rule requiring the dice to bounce off the back wall, which is what I needed to know in my problem with Bellagio. And later, Bellagio managers said I was correct and the table crew was wrong. (They never made good on the two bets I wasn't paid.)
But what I also found out was that the NGC rules about a "legal throw" are not in writing -- anywhere. Call them, if you don't believe me, and ask where to find the official rules for a legal throw -- and the answer is you can't.
New Jersey and some other states actually do have it in writing. See: http://alanbestbuys.com/id322.html
And yes, I agree with you about playing with someone else's card. Yes, it might violate the players club rules, but it can't invalidate a jackpot. I've looked on the Internet including the NGC rules and I can't find any mention of such a rule or regulation that your jackpot can be invalidated.
