During the 1990s, technology began to be used in casinos. Computers and video cameras were routinely used to monitor and supervise games. During roulette, for example, casinos installed betting chips with microcircuitry that could be tracked minute by minute. Roulette wheels were also regularly monitored for statistical deviations, and some games were redesigned to be played in an enclosed environment without dealers or card dealers. Instead, players can simply push buttons to bet.

Today, elaborate surveillance systems allow security staff to monitor the entire casino. Cameras mounted on the ceiling of the casino are able to record any suspicious patrons, and video feeds are archived for later review. While the slot floor is not staffed, there are computer chips embedded into the machines, which determine payouts. While there is no live security personnel on the floor, security staff is always aware of any suspicious activity. Even though casino games are a form of entertainment, they aren’t necessarily a good idea.

While most casinos offer the classics like roulette and blackjack, some are more specialized, offering video poker and unique variations. In addition to the standard table games, there are dozens of video poker games. These games are regulated by state law and are available at a variety of casinos. In addition to slot machines and blackjack, casinos also offer a variety of specialty games, such as scratch cards and lottery games. Many casinos also have arcades. And some even offer bingo and scratch card games separate from the main games.
