Casino (plural casinos) are establishments for gambling. These include card rooms, gaming tables, slot machines, and other games of chance. Some casinos also offer restaurant facilities and live entertainment. In some countries, casinos are operated by government-licensed organizations. Other casinos are private businesses. Some casinos are located in or combine with hotels, resorts, restaurants, retail shops, cruise ships, and other tourist attractions. In the United States, casinos are regulated by state laws.
Modern casinos are like indoor amusement parks for adults. They feature elaborate themes, lighted fountains, spectacular shows, and expensive dining and living quarters. But they wouldn’t exist without the games of chance that draw in patrons. Slot machines, blackjack, roulette, poker, craps and keno provide the billions in profits that casinos rake in each year. Each game has a built in, long-term advantage for the casino, known as the house edge or vigorish. Players who possess sufficient skills to eliminate this advantage are called advantage players or agens.
To maximize their profits, casinos create environments centered around noise, light and excitement. They hire gaming mathematicians to analyze the odds of winning and losing. They also design their games to be as appealing as possible to the senses of sight and sound. For example, electronic machines are programmed to produce pleasing sounds, and the lights on casino floors are electronically tuned to the musical key of C to entice players. In addition, casinos rely on customer service to encourage patrons to spend more money than they intend to. They reward big bettors with free hotel rooms, meals, show tickets and reduced-fare transportation.
