If you haven't played NetEntertainment's Craps before, you should play in practice mode until you get a handle on the rules of the game. Craps is a fun but somewhat intricate game that requires knowledge to play profitably. A roll of the dice starts the game and the first roll of a game is called the Come Out roll.

If you're the Shooter, you have to place a Pass Line or Don't Pass Line bet on the Come Out roll.  Once that's done, you can place other bets on the table. 

If you place a bet on the Pass Line - Throw the Come Out roll.  If you roll a 7 or 11 on the Come Out roll you win. If you roll a 2, 3 or 12 you lose.  If you roll a 4, 5, 6, 8, 9 or 10 that establishes the Point for that game and you roll again. 

If you place a bet on the Don't Pass Line - Placing a bet on the Don't Pass Line has the opposite outcome of the Pass Line bet.  If you roll a 1 or 3, you win.  If you roll a 7 or 11, you lose.  If you roll a 12 you don't win or lose and bet is still on and you roll again.

You can place any combination bets after the Come Out roll.  The game goes on until you roll the point or a 7.  If you roll a 7 all bets are forfeit.  Roll the Point, you win 1:1.  All other bets are still active and you roll again.  If you roll a 4, 5, 6, 8, 9 or 10 that establishes the Point for that game.  You win your side bets when the dice rolls up the betting combination. 

This is the basics and intended just to give you an idea of the game and it's potential. Once you become familiar with it, you'll find yourself really enjoying the game!
