What Is a Casino?


A casino, also known as a gaming house, is an establishment for gambling. While musical shows, lighted fountains, elaborate hotels and shopping centers help lure gamblers, casinos would not exist without the billions in profits generated by games of chance such as blackjack, roulette, craps, baccarat, poker and slot machines.

Gambling in some form has been a part of almost every society throughout history, from ancient Mesopotamia and Rome to Napoleon’s France and Elizabethan England. While some people may consider casinos an abomination, they are the source of many jobs and contribute to local economic development and tourism.

The most popular casino game is the slot machine, which allows players to place a small amount of money and watch as bands of colored shapes roll on reels (whether real physical ones or video representations of them). Each spin costs money, but the outcome depends entirely on luck and not any skill. Most casinos also have a variety of table games, with varying rules and betting limits.

Because of the large amounts of currency handled within a casino, both patrons and employees are sometimes tempted to cheat or steal, either in collusion with each other or independently; therefore, most casinos have security measures to prevent this. These can include security cameras and the ability for staff to look directly down on the activity from catwalks above the floor, through one-way glass. Some casinos also have routines and patterns for each type of game, so it is easier for security personnel to spot anything that deviates from the norm.
