hello mikeg
If you are familiar with the crap tables in Atlantic City and Las Vegas, you would not want to play any of the existing games in DR.
I've played craps at Paradise (Playa Dorada) and Ocean World (Cofresi)
The relationship of minimum to maximum bets, makes it a bad proposition.
They would only allow you single odds when playing the pass line or come bets.
The center bets are horrible; US$ 25 maximum world bet and the same goes for the hard ways. Now, when the minimum bet is US$ 5-10, that'll give you a good idea of your chances.
Play the craps game somewhere else, and enjoy some blackjack, holdem, or 3-card poker, your odds will be much better.
