What is a Casino?

A casino (or gambling hall) is a facility where people can play games of chance for money or other valuables. Most casinos are operated by government-licensed companies or Native American tribes. Casinos are important tourist attractions and contribute to the economy of many states. Casino tourism also creates employment opportunities and boosts the hospitality and entertainment industries.

Like any business in a capitalist society, the casino exists to make money. Successful casinos bring in billions of dollars each year to the corporations, investors, and Native American tribes that own them. State and local governments benefit from the taxes and fees they collect from casino operations.

Casinos use a variety of marketing techniques to attract gamblers. They offer a wide variety of gambling options, including slots, video poker, and table games such as blackjack, roulette, and craps. They arrange these in a mazelike fashion so that wandering patrons are constantly enticed with new options. The machines are designed by computers to appeal to human senses, using bright colors and gaudy lighting to stimulate the eye, and sounds such as bells, whistles, and the “cling clang” of coins hitting the payout tray to appeal to the ear.

In addition, the houses take a small percentage of each bet, a practice known as the vig or house edge. This advantage can be offset by skillful playing (known as basic strategy) or by using card-counting techniques. In games such as poker, where players compete against each other, the house also earns a commission, called rake.
