Casino is a gambling establishment that provides customers with a wide variety of gaming options, such as slots, table games and bingo. Some casinos specialize in one type of gaming, while others have a mix of all types. There are also online casinos that focus on certain types of gaming. Some of these focus on video poker, while others have a lot of slots and jackpots.
Gambling almost certainly predates recorded history, with primitive protodice and carved six-sided dice found at archeological sites [Source: Schwartz]. The modern casino as a place to find several ways to gamble under one roof developed in the 16th century during a gambling craze among Italian aristocrats, who held private parties called ridotti in which they could wager large sums of money.
The modern casino is a complex environment that requires a significant amount of security to prevent cheating and theft by patrons, in collusion with staff or independently. Cameras are the most basic element of this protection, but casinos also employ other methods to prevent crime. Security begins on the casino floor, where employees keep a close eye on players to spot any blatantly obvious tricks like palming, marking and switching cards or dice. Table managers and pit bosses have a wider view of the game, and watch for betting patterns that might indicate fraud.
Comps, or complimentary goods and services, are another method used by casinos to keep their best players coming back. These include free hotel rooms, meals and even airline tickets for high rollers who spend a lot of time playing slot machines and table games.
