I'm not a craps expert and don't know the bubble craps layout but I think the worst bet in craps is the Any Seven. It's 5 to 1 against and pays 4 to 1. You figure the return by dividing 5 by 6 for 83.3333%. That fits Nevada state law which I think is at least a 75% return. The bet has a 16.7% house edge.
As far as video poker goes a person can easily destroy the return of the game, well below the state minimum, by card selection....like holding 8-6-3 offsuit ensuring the biggest hand you could hit would be 3 of a kind. And the odds would be 119 to 1 of even that happening.
