What Is a Casino?

A casino is an establishment for certain types of gambling. These facilities are often combined with hotels, resorts, restaurants, retail shops and other tourist attractions. They may also host live entertainment, such as stand-up comedy or concerts. In some cases, casinos will provide separate entrances and/or exits for non-gambling patrons, as well as security measures.

In many games that have a skill element, the house edge – the mathematically determined profit margin for the casino – can be less than two percent. However, this advantage can vary widely depending on the rules of the game, the amount of money wagered and whether players use basic strategy. Casinos also earn money from a commission on video poker and slot machines, which are played at high volumes and at rates of five cents to a dollar or more per spin.

Gambling in one form or another has been part of human society for millennia. Evidence of dice games dates back to 2300 BC, while the first card games appeared in Europe around the 1400s. The first modern casinos grew out of taverns that offered gaming and other forms of entertainment in the 19th century.

Something about the casino environment seems to inspire people to cheat, steal and scam their way into a jackpot. As a result, casinos spend a large amount of time, effort and money on security measures. These can include cameras, staff monitoring and vigilance in front of the tables, and even catwalks that allow surveillance personnel to look down through one-way glass at the games on the floor below.
