"The basic idea behind Craps is to establish a "point" number and roll that number again before rolling a 7 (craps). Only the numbers 4, 5, 6, 8, 9, or 10 can be a point number and all other rolls on the dice have special meanings depending on when they are rolled (before or after a point is established).
A new game in Craps begins with the ""Come Out"" roll. A ""Come Out"" roll can be made only when the previous shooter fails to make a winning roll -- more correctly known as "not making the "Point"" or "seven out". A new game then begins with a new shooter. If the current shooter does make his "Point", the dice are returned to him and he then begins the new "Come Out" roll. This is a continuation of that shooter's roll, although technically, the "Come Out" roll identifies a new game about to begin.
When the shooter fails to make his or her "Point", the dice are then offered to the next player for a new "Come Out" roll and the game continues in the same manner. The new shooter will be the person directly next to the left of the previous shooter.
On the "Come Out" roll, the "Pass Line" bet wins if the shooter rolls a 7 or an 11. The bet loses automatically if the shooter rolls 2, 3 or 12. This is known as "rolling craps". If the shooter rolls 4, 5, 6, 8, 9 or 10 the shooter must roll this same number again (to win) before rolling the number 7. Rolling any of these numbers on the "Come Out" roll is called "establishing the "Point". Any number so rolled is thereafter referred to as the "Point".
Establishing a "Point" is an event that happens as the immediate result of the "Come Out" roll, unless that "Come Out" roll results in 7, 11, 2, 3 or 12, in which case more rolls must be made until a "Point" is established.
In Craps, winning or losing depends on a variety of different possible outcomes on any roll of the two dice. The two dice can produce many different number combinations; some can be made several ways, others only one way. For example, two dice can roll the number 6 as follows: 5/1, 4/2, 3/3, 2/4 and 1/5. But the number 2 can only be rolled one way: 1/1.
Numbers such as 6, which can be rolled several ways, don't pay as much as numbers which can be rolled only one way, unless you are betting that the number will be rolled in a specific way, such has 3/3, known as "Hard ways". All winning payoffs are, therefore, determined by the frequency in which any two-dice number combinations can be rolled. Generally, the harder the combination is to roll, the more it will pay, and vice versa.
Although really taking advantage of the many betting options can involve a considerable degree of mastery, in its simplest form, Craps is a game where players bet either that the shooter will make his "Point" or that he or she will not make their "Point". Betting that the shooter will make his/her "Point" is called betting "with the shooter" (also called "betting right") and betting that the shooter will not make his/her "Point" is called "betting against the shooter" (also called "betting wrong").
To bet with the shooter, you must place your bet in an area marked ""Pass Line"", before the new shooter rolls the dice. The so-called "Pass Line" is a strip on the table layout marked by two lines roughly two inches wide and it rims the entire table layout across from the Box Man. To bet against the shooter, you must place your bet in an area marked "Don’t Pass". This area is also a strip on the table layout and it rims the table directly above the "Pass Line".
No matter what stage the game is in, whether on the "Come Out" roll, or in progress, you can jump in immediately and place any bets. The only exception to this is the bet called the "Pass Line" bet with odds", which can be made only on the "Come Out" roll. You can, however, bet with the shooter even while the game is in progress by placing a "Pass Line" bet without odds. Placing your chips halfway over one of the two lines framing the "Pass Line" area does this.
Before the new shooter rolls the dice on his or her "Come Out" roll, there are a variety of bets that can be made. The "Pass Line" and Don’t Pass Line" bet are the most common bets to make. Once the shooter establishes a "Point", you can then place an additional bet behind your "Pass Line" bet. This is called "taking odds".
In most casinos you can bet up to three times the amount of your "Pass Line" bet. This is called "taking full odds". Some casinos offer up to 100 times odds! This simply means that you can bet up to 100 times the amount of your "Pass Line" bet once a "Point" has been established.
Betting the "Don't Pass Line" is the exact opposite of betting the "Pass Line". The "Don’t Pass" bet wins if the shooter rolls any craps; 2 or 3 (12 is considered a push; the bet neither wins nor loses, merely stays in limbo till a decision is reached on subsequent rolls) and loses if shooter rolls a 7 or 11.
Once the shooter establishes a "Point" your "Don’t Pass" bet stays in action, win until the shooter rolls a 7 or make his/her "Point". Therefore, a "Don’ Pass" bet wins if the shooter fails to make his "Point", but loses if the shooter does make the "Point". You can also take odds on a "Don’t Pass" bet."
