What is a Casino?

A casino (also known as a gambling house or a gaming club) is an establishment offering various types of gambling. Some casinos are combined with hotels, restaurants, retail shops, and entertainment venues. In some countries, casinos are licensed and regulated by government authorities. The precise origin of gambling is unknown, but it is widely believed to have been a feature of human civilization for millennia, with the first evidence appearing in 2300 BC China.

Gambling in some form or another is widely practiced throughout the world and is one of the most popular forms of entertainment. While the vast majority of casino games involve pure chance, some do require skill and expertise to have a higher chance of winning. These are commonly known as skill-based games.

Most modern casinos employ various technological measures to control the flow of money and prevent cheating. These include video cameras that monitor all activity, chip tracking systems to ensure that players are betting within their limits, and electronic surveillance systems that watch for statistical deviations from expected results. These systems are normally operated by highly trained gaming mathematicians and software engineers, who may be contracted by a casino to do so.

Despite their reputation for flashing lights and free cocktails, casinos are in fact engineered to slowly bleed their patrons of cash. As such, mathematically inclined minds have sought to turn the tables on a system they perceive as rigged. Physicists, in particular, have long been a focus of such attempts, with some even managing to win a few bucks while playing slot machines.
