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.

The odds bet is the best wager you can make in the game of craps, because the house has no built-in advantage. Some casinos permit players to make double odds, and even greater odds wagers. The odds bet not only has no house edge associated with it, but has no official designated space on the craps table. to take the odds, you must place the appropriate amount of chips behind your pass line bet in the open area of the craps layout.
