Statistics show that more than a quarter of Americans visited a casino in the past year. In 1989, 24% of adults had some college credits, and 28% had a graduate degree. Today, nearly half have no formal education. Throughout the 1990s, casino gaming technology increased dramatically, with video cameras and computers routinely overseeing the game floor. Additionally, “chip tracking” involves betting chips with built-in microcircuitry that allows casinos to monitor each player’s wager minute-by-minute. Roulette wheels are also monitored regularly for statistical deviations. Enclosed versions of the game are also popular, and allow players to place their bets by pushing buttons instead of dealing with a dealer.
Security in a casino starts on the casino floor. Employees monitor each game and patrons, and keep an eye on their behavior. Dealers are focused on the game and can easily spot someone trying to cheat. Table managers and pit bosses keep watch over the floor as well, keeping an eye on betting patterns and suspicious patrons. Every casino employee has a higher-up person monitoring their activities. By monitoring all these people, the casino can ensure that no one gets away with cheating.
Most casinos offer blackjack, roulette, video poker, and slot machines. Exceptions include 3D slots, live table games, and casino-exclusive games. Many casinos work with multiple software companies, which affect game rules, payouts, odds, and the variety of games available. Some casinos have arcades and separate categories for scratch cards and bingo. In addition to slots, most casinos feature poker, bingo, and other games. They may also have specialty games such as keno.
