A Casino is like an indoor amusement park for adults. The vast majority of the entertainment (and profits for the owners) comes from gambling. While musical shows, lighted fountains and shopping centers help attract people to casinos, the games of chance that actually make them money are slot machines, blackjack, roulette, baccarat, craps and keno. These games and the millions of dollars of bets they take each year provide the billions in profits that casinos rake in every year.

Gambling in some form almost certainly predates recorded history, with primitive protodice and carved knuckle bones found in archaeological sites. However, the casino as a place to find multiple ways to gamble under one roof did not develop until the 16th century. A gambling craze swept Europe, and Italian aristocrats often hosted private parties called ridotti in their homes. These allowed them to play a variety of games while keeping their wealth hidden from others.

Modern casinos are not only massive gambling facilities, but also prime dining and drink establishments and performance venues. One of the most prestigious of these is the Monte-Carlo Casino which is located in Monaco and is renowned for its music performances and other attractions.

Casinos spend a lot of money on security. They have a high number of employees on the floor who watch over each patron to make sure that they are not cheating or stealing. They use cameras to monitor all activities in and around the casino and can eject anyone who appears to be a problem. Security staff look for patterns in how players react to different scenarios, making it easier to spot a potential problem.
