The first thing you need to know about craps is that when you’re buying in (exchanging cash for chips), the dealer can’t actually take the money from your hand. You’ll need to put your money on the table (between rolls of the dice, please!) and say, “Change, please.”
It’s a good idea to make eye contact with a dealer during this process, otherwise your cash on the table might be mistaken for a bet. (Most casinos insist you bet only with chips, but some let you play with cash, usually for just one bet.)
Once you’re given the chips, make sure to count them. Dealers are usually spot-on in their math, but they’re also human.
Next, it’s time to dive in. As a beginner, take it slow. Ask questions. Stick to the basics at first. Oh, and make sure everyone at the table knows you’re a first-time shooter when you get your hands on the dice. Craps players love a “virgin.”
The most important rule of craps? Have a blast. There’s a reason you can always tell where the craps tables are in a casino. That’s because craps players are usually having the most fun.
Bonus trivia: The outside corners of a craps table are called "the hook."
