A casino (also called a gambling house or a gaming palace) is an establishment for certain types of gambling. Some casinos are standalone, while others are attached to hotels, resorts, or restaurants. In some countries, casinos are licensed and regulated by government agencies. In the United States, there are several laws that govern casino operations.

Casinos typically offer a variety of table games, including blackjack and poker. Many of these casinos also feature live sporting events and other types of entertainment. In addition to traditional table games, most casinos have a wide range of slots. Some even offer video poker and other games that combine elements of skill with chance.

The house edge of casino games is mathematically calculated, and the odds of winning a specific game at a particular casino are always in favor of the house. This fact, coupled with the high-stakes nature of casino gambling, leads some patrons to consider casinos rigged or unfair. This perception is exacerbated by the high amount of money that can be won in a short period of time, and by the euphoric atmosphere created by flashing lights and loud noises.

The euphoric feeling produced by the casino environment can be addictive and dangerous for some people, especially if they have a gambling problem. A person with a gambling addiction may find it difficult to leave a casino, and can spend hours at a time at a single machine in a trance-like state.
