In order for the reader to understand how the game works, it is important to understand the Craps rules. If you don't, there is no point in playing unless you are an excellent gambler with a large portion of luck.
In Craps the players play against the bank through the result of a pair of die, that is, the sum of two dice. There are approximately 40 different possibilities to implement around a Craps table but there is really only one basic rule which you have to know about and be able to handle. This involves so-called Pass Line Bets.
A Pass Line Bet means placing a number of markers on the pass line before the Shooter throws the dice. The first throw has a special name and is called the come out roll. If the Shooter rolls a 7 or 11, you win a pass line bet. If the sum 2, 3 or 12 is delivered, you lose a pass line bet. This result is usually called the craps numbers and means that you lose, but still allows you or the person who is the Shooter to continue to roll the dice.
All other sums shown are called the point or the point number. If you haven't already figured this out then these numbers are 4, 5, 6, 8, 9 and 10, Box numbers. The reason for this name is that they are printed on the layout of a Craps table. The number which becomes the point number is marked by a marker by the Dealer in order to show all players around the table which number is the point number. This number is that combination which the Shooter must get in a throw of the dice without the dice showing a total of 7 at any time. Should 7 be thrown, they lose their bet on the pass line.
