The game of Craps revolves around dice. Wagers are made upon the result of a single roll, or a series of rolls, of a pair of dice. Craps is a game of probabilities and odds, so any discussion of Craps will benefit by a brief explanation of the probabilities involved. Since the game uses two dice, a shooter (the person rolling the dice) can roll any number between 2 and 12. It is important to understand that some numbers are more likely to appear than others on a single roll of the dice.
