A casino, also known as a gaming establishment or a gambling house, is a place where people gamble. It can be found in both land-based and online environments. People gamble by placing cash or other objects into various games of chance, such as slot machines, baccarat, blackjack, roulette and poker. Casinos also offer other types of entertainment, such as shows and concerts.

There are a number of ways to protect players and casinos from cheating and theft. Video cameras are common, as are rules requiring players to keep their hands visible at all times while gambling. Casinos may also employ technology such as chip tracking (which allows a casino to see the exact amount wagered on each chip minute-by-minute), and automated systems for games like poker that don’t involve dealing.

The casino also houses an art gallery, a theatre and three restaurants.
