Many craps players, including both casino craps players and Internet craps players, enjoy playing craps for many years purely with the Pass Line Bet. It is the classic craps bet, and they see no reason to stray from it.
There are others who believe that the best craps strategy is to learn the other craps bets, such as the Don't Pass Bet, Come Bets, Place Bets, and Field Bets, and to mix them up to keep things exciting.
The choice, of course, is up to you. It is definitely best to start with the Pass Line Bet, and then you can decide whether to stick with it or to branch out into the other craps bets.
