Casinos are gambling establishments that offer a variety of games of chance, in some cases with an element of skill, and pay out winnings based on the amount of money bet. Some casinos also have restaurants, bars and meeting and convention facilities. Casinos make their profits by taking a percentage of all bets placed or, in the case of video poker and some table games, from each hand played.

Something about the nature of gambling encourages people to cheat and steal, either in collusion with others or by themselves, which is why most casinos spend a great deal of time and money on security measures. These may include a full compliment of surveillance cameras, which monitor patrons from many angles and can detect any tampering or movement that might indicate cheating. Casino floor employees are constantly on the lookout for blatant cheating, such as palming, marking and scheming to throw the game; pit bosses and table managers supervise the casino tables with a more sweeping view and watch for betting patterns that might signal attempts to collude.

In addition to the cameras and staff, some casinos are known for their ostentatious architectural style, with one of the most famous being Caesars Palace in Las Vegas, which was designed to make visitors feel like they were in a Roman emperor’s palace. Other casinos have been designed to attract specific types of tourists, such as the Hotel Lisboa in Macao, which was built to look like a birdcage.
