When you hear the word Casino, most people imagine a large hotel-resort complex in Las Vegas gleaming with neon lights and offering mindblowing gambling. However, there are many casinos located outside of Nevada. They include Atlantic City, New Jersey, and some on Native American reservations in Iowa and other states. They also are found in other countries around the world. These casinos rake in billions of dollars each year and benefit local governments, private corporations, investors, and Native American tribes.
Most of these facilities feature a wide range of games including poker, blackjack, slot machines, roulette, craps, and more. They also offer non-gambling areas like restaurants and bars, swimming pools, and spas. Casinos are highly sophisticated businesses that utilize advanced technology to ensure the safety of patrons and their money. For instance, chips with built-in microcircuitry allow the casino to monitor exactly how much is being wagered minute by minute and to warn players of any abnormalities; likewise, roulette wheels are electronically monitored regularly to discover any statistical deviations from their expected results.
Because of the huge amounts of cash handled within a casino, both patrons and employees may be tempted to cheat or steal from each other or from the house. To combat this, most casinos employ security measures including surveillance cameras. Additionally, windows and clocks are seldom seen in a casino; this eliminates distractions and allows gamblers to lose track of time and their spending. Casinos also rely on psychology to lure and keep gamblers in their establishments. They invest millions of dollars in determining what colors, sounds, and scents appeal to the human senses.
