Plot hole: The rigged dice, while undetectable, wouldn't necessarily work. While they have the ability to turn the dice they still don't know what number the dice will land on and which way the dice will roll when triggering the lighters. Granted they can keep someone from losing by triggering the dice, they can't always make someone wins. And most of the bets that were placed (Rusty's Snake Eyes bet) are 1-roll bets, i.e. if you don't hit on that roll, you lose.
