A casino, or kasino in Spanish, is an establishment for gambling and games of chance. Modern casinos are often combined with hotels, restaurants and shopping areas. In many countries, the operation of casinos is regulated by law.

Whether the casino is on a strip in Las Vegas or a small building in rural Canada, there are some things they all have in common. They are designed to keep gamblers happy and distracted from thinking about how much money they might be losing, largely by making the environment as comfortable as possible. This includes lush carpets, elegant decor and carefully designed lighting to make patrons feel they are in an exclusive club.

They also have built-in advantages to make sure the house always wins. These are called the “house edge” and they are the average gross profit that a casino expects to make on all bets placed in a particular game. Casinos use a variety of methods to ensure this advantage, including ensuring that all bets are made with chips (which help the casino track patrons and their movements), employing high-quality dealers, using video surveillance, and making sure that all bets are placed in the right place.

Casino security is usually divided into two departments, a physical force and a specialized surveillance department that runs the casino’s closed circuit television system, which is referred to as the “eye in the sky.” This surveillance technology allows for a great deal of detail to be observed, and the video feeds can even be adjusted to focus on specific patrons.
