In the casino game of Craps, the house retains the advantage as far as the winning odds are concerned, as is the case with any other casino game. That being said, there are many bets that the gambler can make in the game of Craps that improve their odds and conversely, there are many Craps bets that greatly increase the odds of winning for the casino. There is an odds bet that can be placed in certain situations that can significantly increase your odds of winning or lower the house odds, but at no time does the casino actually lose their advantage in the game of Craps. 

Craps is considered to be mostly a game of luck rather than skill, but knowing how to play craps and your odds of winning can greatly improve your success as a craps player.
