What Is a Casino?

A casino is an entertainment complex, often located in a resort, that offers patrons the opportunity to gamble. The most popular games are poker, blackjack and slot machines, which offer players a chance to test their wits in an exciting competition of strategy and skill. The atmosphere in casinos is fast-paced and full of energy, and the rush of winning can make even the most jaded person feel on top of the world.

While some casinos may have other types of entertainment, such as concerts or shows, the vast majority of a casino’s profits are generated by gambling. Slots, black jack, roulette, craps and other games provide the billions in profit that casinos rake in every year. While some games do have a skill element, the house always has a mathematical advantage over players, and the average expected value of a bet is uniformly negative.

Something about gambling seems to inspire people to cheat, steal and scam their way into a jackpot. This is why casinos spend a significant amount of time and money on security. Elaborate surveillance systems feature cameras that can watch every table, window and doorway at once, and are adjusted to focus on suspicious patrons by employees in a room filled with banks of monitors. Table managers and pit bosses also keep a close eye on their tables, making sure players are not palming, marking or switching cards and dice.
