A casino is a gambling establishment that offers a variety of games that involve chance and skill. Most casinos offer slots, table games such as craps, blackjack, baccarat and roulette, and video poker. Casinos also offer a wide variety of betting limits and rules. In addition, some casinos host international championships of poker games.

The etymology of the word casino dates back to Italy, where it originally meant something like a villa or summer house or social club. Modern casinos are more like indoor amusement parks for adults, with billions of dollars in profits raked in each year from various gambling-related activities such as slot machines and black jack. The majority of these casinos feature a substantial amount of poker-related action, as the game is one of the most popular in the United States and home to several World Series of Poker events each year.

Due to the enormous amounts of money handled, both patrons and staff may be tempted to cheat or steal. To combat this, casinos use a variety of security measures. Video cameras are common, as are security personnel at gaming tables. In addition, many casinos employ technology such as chip tracking to monitor bets minute by minute and alert employees if a bet is unusually high or low.

In addition to gambling, casinos usually have restaurants, hotels, non-gambling entertainment and other amenities to appeal to visitors. However, some economists argue that the net value of a casino to a local economy is negative due to the fact that it shifts spending away from other forms of entertainment and can lead to compulsive gambling.
