A casino, or gambling house, is a place where various forms of chance-based games can be played. Generally, these include card games such as poker and blackjack, dice games such as craps and roulette, and other games of chance such as slot machines and video poker. Many casinos also have restaurants, bars and stages for live entertainment. In addition, they often offer hotel rooms and other services such as retail shopping.

While some casino games have a skill element, the odds for most casino games are always stacked in the house’s favor. This advantage, which is mathematically determined, is referred to as the house edge. Despite the fact that the odds are against players, it is possible to win money in a casino, if the player is careful and plays within his or her budget.

There are few places better known for casino gambling than Las Vegas, although the number of casinos has grown steadily as more states have legalized gaming. The casino industry is one of the world’s fastest-growing, and it is often combined with other forms of entertainment to attract tourists and locals alike.

Security in a casino starts on the casino floor, where casino employees keep an eye on all the action and patrons to make sure no one is cheating or stealing. Dealers are heavily trained to spot blatantly obvious attempts at cheating, such as palming cards or marking and switching dice. Pit bosses and table managers have a broader view of the tables to catch more subtle betting patterns or telltale signs of cheating by other patrons.
