What Is a Casino?


A casino is an establishment that offers a variety of games of chance. It also provides a large selection of amenities to attract players.

Casinos can be found in almost every country around the world, including some that are not even regulated by their local laws. They are usually found in cities, towns and tourist attractions that draw visitors.

Typical features include top-notch hotels, spas and restaurants, as well as live entertainment, slot machines, and poker rooms. Some casinos offer thousands of slots and other forms of entertainment, while others specialize in more traditional table games like blackjack and roulette.

The Casino Advantage

There is a small, built-in statistical advantage that casinos have over their patrons. This allows them to make money on every game they offer, whether it is a casino card game or a slot machine.

The casino edge can be very low (less than two percent) but over time and millions of bets placed by their patrons, it can be enough to earn them a substantial income. This gives them the ability to build elaborate hotels, fountains, towers and replicas of famous landmarks.


Security in a casino starts on the floor, with dealers and pit bosses keeping an eye on all players. They can spot cheats easily, such as palming or marking cards and dice, or stealing from other players. They also monitor betting patterns and routines. In addition, some casinos have catwalks in the ceiling above their tables and slot machines, so surveillance personnel can look directly down on their activities.
