What is a Casino?

A casino, or kasino (from the Latin for “gambling house”), is an establishment where people can gamble. Some casinos offer a wide variety of games, while others focus on a specific type of gambling. In some cases, casinos are combined with hotels, restaurants, retail shops, and other attractions.

Beneath the flashing lights and free drinks, casinos stand on a bedrock of mathematics, engineered to slowly drain their patrons’ cash. For years mathematically inclined minds have tried to turn the tables, using their mastery of probability and game theory to exploit weaknesses in a system that’s fundamentally rigged.

Many casino games involve a degree of skill, but the vast majority are pure chance. As a result, the mathematically predictable long-term advantage of the house in casino games (known as the “house edge”) means that most players will lose money over time. In rare cases, players with sufficient skills can eliminate the house edge and make a small profit over time; such players are known as advantage players.

Most casinos rely heavily on technology to monitor player activity and the performance of their machines. For example, in some games, betting chips have built-in microcircuitry that allows them to be monitored minute-by-minute, so the casino can quickly discover any statistical deviation; and roulette wheels are electronically monitored to ensure they produce random results. In addition, many casinos use video cameras for general security purposes.
