A casino is a gambling establishment that offers games of chance. Slot machines, blackjack, roulette, craps, and baccarat are the popular casino games that draw in billions of dollars each year for their owners. In addition to making profits, casinos provide entertainment for gamblers and contribute to tourism.

According to a 2002 survey of Nevada residents conducted by Gemini Research, the majority of people who play casino games choose to gamble on slot machines. Table games (such as poker, craps, and roulette) are less popular. Keno, bingo, and gambling on sporting/racing events have a much smaller percentage of the overall gambling market.

In order to attract customers, casinos focus on creating stimulating atmospheres and offering customer service. They also offer perks designed to encourage gamblers to spend more money. These perks are called “comps,” and they usually involve free items. The strategy was effective during the 1970s, when Las Vegas casinos offered deeply discounted travel packages and cheap buffets.

Despite their popularity with many gamblers, casinos are not without their dark side. In the past, some casinos have been criticized for being corrupt, with employees accepting bribes and taking advantage of vulnerable customers. Others have been accused of fostering gambling addictions. In some cases, the presence of a casino can hurt property values in nearby neighborhoods. The government has taken steps to regulate casinos. Federal taxes are payable on all casino winnings. However, gamblers can deduct their losses on tax returns if they keep careful records of their gambling activities.
