The progress of a game of Craps is marked with a plastic "puck", which is black on one side (OFF) and white on the other (ON) The first roll of the dice in a round of Craps is called the come-out roll. The puck is turned black side up (OFF) during the come-out roll. The basic opening bet in Craps, placed just before the come-out roll, is called a Pass Line bet. The Pass Line bet wins immediately if the come-out roll is 7 or 11 (natural), and loses when the come-out roll is "Craps" (2, 3, or 12) If a 4, 5, 6, 8, 9, or 10 is rolled on the come-out roll, that number becomes the point. The puck is placed on the Craps layout over the box displaying the numbered rolled as the point with the white side up (ON) The shooter now keeps rolling the dice until either the point is repeated or a 7 is rolled to end the round. If the point repeats first, the Pass Line bet wins. If a 7 is rolled first (seven out), the pass line bet loses.

For gambling to remain fun, you need to know that you are not spending more than you can afford. Gambling operators are trying their hardest to get you to play for as long as possible – so it is very easy for you to spend more than you can afford. Setting a limit for your turnover (or losses, if that is easier) and keeping records help you to know how much you are spending. Use the gambling diary that is part of the game Guide to keep track of your wins and losses.

The inside walls of the table are covered with a serrated egg-carton like foam, designed to make the dice bounce around to assure randomness. Each throw of the dice is called a "roll". Players take turn rolling the dice, clockwise around the table, and the player rolling at any given time is called the "shooter". When a new shooter is given the dice, his or her first roll is called the ""Come Out"" roll. This begins a new series of rolls by that shooter and lasts for as long as that shooter continues to make winning rolls.

The game of Craps revolves around dice. Wagers are made upon the result of a single roll, or a series of rolls, of a pair of dice. Craps is a game of probabilities and odds, so any discussion of Craps will benefit by a brief explanation of the probabilities involved. Since the game uses two dice, a shooter (the person rolling the dice) can roll any number between 2 and 12. It is important to understand that some numbers are more likely to appear than others on a single roll of the dice.
