A Casino is an establishment that provides gambling-related activities. It may offer a variety of games that depend on chance, some with an element of skill, such as roulette, craps, blackjack, and video poker. A casino may also provide complimentary items to players or host events like poker tournaments, shows, and dinners. Some casinos may be large enough to have hotels, restaurants, non-gambling game rooms, pools, bars and spas.

In addition to traditional table and slot machines, modern casinos often feature more exotic offerings, such as electronic gaming tables and simulated horse racing. The most famous casinos are found in Las Vegas and Atlantic City, but there are also many others around the world.

Casinos are places where large sums of money change hands, so they need to have a high level of security. Most of this is based on cameras, but some casinos use additional methods to prevent cheating and theft. For example, dealers at card games are not allowed to change small denomination chips for larger ones; if they want to do this they must go to the cashier’s booth and ask to “color up.” Because of the large amounts of currency involved in a casino, employees and patrons may be tempted to cheat or steal, either in collusion with each other or independently. Because of this, casinos devote a lot of time and money to security measures.
