A casino is a building or room where games of chance are played for money. The word is derived from the Italian casona, meaning a “small house.” Although many people think of Las Vegas when they hear the word casino, there are actually more casinos in the world than you might imagine. Some are quite large resorts, like Monte Carlo and Casino Lisboa, while others are more modest buildings that still offer gambling activities.

Something about the nature of gambling (or maybe just the fact that it involves lots of money) encourages some players to cheat or steal, either in collusion with other players or independently. In order to prevent these activities, most casinos have security measures in place. These might include cameras throughout the facility and rules about how players should conduct themselves.

In addition, most casinos employ security personnel to monitor games and patrons. Some of these staff members are trained to detect telltale signs, such as an erratic betting pattern or a player’s inability to maintain a conversation while playing cards. Other staff members are assigned to specific areas of the casino, where they can be alerted quickly to any suspicious activity.

As you might expect, the most famous casinos are those that have been featured in movies and TV shows. These include the Bellagio in Las Vegas, the Hippodrome in London, and the Casino de Monte-Carlo in Monaco.
