Note: This is the most confusing thing to new craps players.
Note that rolling a 7 after a point is established is a loser, which is opposite of the 7 being a winner ON A COME OUT ROLL.
Remember this key point and you're a craps player!
Each dealer has a hockey-puck-looking disk (called a "buck") which is white on one side and black on the other. When a shooter establishes a point, the buck is placed on the point number (on the layout) white side up. When there is no point established, the buck is turned black-side up and set off to the side of the layout.
You can only place a Pass Line bet at the start of a series (on a come-out roll when there is no point established - i.e. when the buck is black-side up and off to the side). However, some casinos may waive this traditional rule and let you put down a Pass Line bet at any time. Ask a dealer.
The same shooter rolls the dice continuously until they "seven out". No matter how many times they roll a "come-out 7 or 11", craps (come-out 2, 3, or 12), or a point, the shooter gives up the dice only after they "seven out" (i.e. roll a 7 when trying to roll a point) or voluntarily opt out. In other words, the same shooter can have multiple "come-out " rolls and make multiple points before they seven out. (A shooter with many come-out rolls is called a "hot shooter" because they have made multiple points - i.e. they didn't throw a 7 while points were established.)
If you need chips, lay your money down on the layout in front of a dealer. Never try to hand money to a dealer directly. Also, check to make sure the shooter is not about to roll the dice before you put your money down (so you don't interfere with the dice). Most craps tables have a $5 minimum bet level so when you lay your money down, ask the dealer for "nickels" ($5 chips). (Some of the smaller places may have minimum bet levels of $1, $2, or $3.) If the buck is turned white-side up and is on a number (see diagram above), wait for the series to end and then place your bet (chips) on the Pass Line area of the layout directly in front of you. (This is how the dealers know which bet belongs to which player.) Once a Pass Line bet is down it cannot be removed.
Players take turns being the shooter, going from one player to the next in a clockwise direction around the table. You can pass on being a shooter if you wish, but who knows, you could have the hot hand! When it is your turn to be the shooter, the "stick man" pushes four to six dice in front of you. You select two of the dice and he retrieves the remaining ones. Only use one hand when handling the dice. (If you use two hands they fear you may be switching dice and will force you to re-select from new dice.) Throw the dice to the opposite end of the table. The dice must hit the end wall and bounce back in order to be a valid roll. Also, you must have a Pass Line bet down in order to shoot.
Craps offers players some of the best odds in the house. The Pass Line bet only has a house edge of 1.414%. If you put down "double odds" (which you can learn about on the Intermediate page) with your Pass Line bet the house's edge drops to .606%. Compare that to the house edge of 5.3% for roulette and about 1.5% for blackjack (when you use the basic strategy in a multi-deck game).
