I have found some rules for you in wiki.
Know the personnel.When you walk up to any table, you'll want to know just who you're dealing with. Because craps involves the most money out of any standard craps online, you can expect to be working with a fair amount of employees.
Familiarize yourself with the table.Casinos aren't meant for customers to be scared away by feeling intimidated -- the craps table is simple once you've studied it for a minute.
Learn the lingo."Comin' out. Bet those hard ways. How about the C and E? Hot roll comin', play the field. Any mo' on yo?"Did you catch any of that? Odds are that's what you'll be hearing when you saunter up to a game in progress.
Get "superstitious".Just like any avid gambler, the gods of luck must not be scoffed at, lest ye want your money revoked. Avoid certain habits (and do others) to look like a seasoned pro (literally) and not drive the others away, leaving you with nothing but nasty glares for companionship.
