A casino, also known as a gambling establishment, is a facility that houses and accommodates various types of gambling activities. These activities are usually associated with games of chance. The most common games are poker, blackjack, craps, roulette and slot machines. Other popular casino games include bingo and keno. In addition to gambling, casinos often provide perks to attract customers, such as free drinks and hotel rooms. These are referred to as comps. In modern times, casinos are most commonly found in combination with hotels, restaurants, retail shopping, cruise ships and other tourist attractions.

Something about casinos seems to encourage people to cheat, steal and scam their way into winning a jackpot. As a result, casinos spend a lot of time and money on security. Security begins on the casino floor, where employees keep an eye on patrons and watch for blatant cheating or other irregularities. The employees are trained to notice patterns, such as a player repeatedly raising or lowering his bets. This helps the security staff to spot suspicious behavior before it becomes a problem.

Casinos are an important part of the gaming industry and are most commonly found in the United States, Europe, Japan and South Korea. However, they are beginning to open in many other parts of the world as well. Whether they are a part of a resort or stand alone, most casinos are designed around noise, light and excitement to encourage gambling. The casino industry has grown to be a major source of revenue for many governments.
