Two men banned from all Nevada casinos due to 2012-14 craps scam at Bellagio
https://www.reviewjournal.com/busine...craps-1527928/
They were making "hop bets", where the player bets on the numbers on each die. Here's an explanation of hop bets: https://www.888casino.com/blog/craps.../craps-hop-bet
The scam involved collusion with a craps dealer. Since there is no place on the craps felt for a hop bet to be made, the bet is verbalized after placing chips on the felt, and it's up to the dealer to fairly pay it. It's one of very few bets at Vegas table games which are not explicitly clear by where the chips are on the felt.
The player would say "hop bet" and mumble something that sounds like numbers, and then whatever lands, the dealer will pretend to have heard those numbers, and pay the players.
The article says that the guys hit a "452 billion to 1" bet, but that's not possible on hop bets, are there are only 36 possible combinations on 2 dice.
I'm guessing the 452-billion-to-1 thing was the fact that they won a super-improbable succession of bets where the odds were 1-in-36 each.
They were arrested and convicted already, but the bans just came down this week.
