True, at first glance, a craps table layout looks quite confusing. There are a variety of bets that you can make, and everything seems so complicated. Actually the basic game is quite simple and easy to learn. Craps involves rolling a pair of dice. When two dice are rolled, any number between 2 and 12 can come up.
Some numbers appear more often than others.
For example there are six different ways to roll a 7, but only one way to roll a 2 or a 12. As you can see 7 is the most frequently rolled number, that's why the game revolves mostly around that number. The number 7 wins only if it comes up on the come-out roll. If it' is rolled while the shooter is trying to repeat his point number, the 7 loses, but the point number wins. More about that in a moment.
