A casino is a gambling establishment that offers games of chance. Its most popular offerings include blackjack, roulette and slot machines. Many casinos also offer tournaments and cash games. They can be found in massive resorts such as the Venetian in Las Vegas or in smaller standalone facilities. Some are even located on boats or barges traveling on waterways. Successful casinos bring in billions of dollars each year for the companies, corporations, investors and Native American tribes that operate them. They also generate tax revenues for state and local governments.

Casinos attract gamblers with lavish perks designed to persuade them to spend more than they intend to. The perks are known as “comps,” and they can include free show tickets, reduced-fare transportation, hotel rooms and meals. High-stakes gamblers are ushered into private rooms away from the main casino floor, where their betting limits can be in the tens of thousands of dollars. In exchange for their large stakes, these players receive exclusive services such as a personal VIP manager and luxury suites.

Casinos are often decorated with bright, gaudy colors that are intended to stimulate the senses and encourage patrons to gamble. They are designed to be noisy and exciting, and the absence of windows and clocks helps patrons lose track of time. The use of red is a common design element because it is believed to be psychologically stimulating. Casinos are governed by strict rules to prevent cheating and other crimes.
