The game selection at a casino can be quite extensive. Typically, a casino will offer blackjack, various table games, video poker, slots, and roulette, although there are some exceptions, such as 3D slots and live table games. While some casinos may employ their own in-house gaming experts, others will outsource the work to companies specializing in the field. A casino can have hundreds or even thousands of games, depending on the type of games it offers and the type of money it’s willing to invest.
Most casinos have a set limit for bets, meaning patrons can’t win more than the casino can afford to pay out. Because the casino accepts all bets, it has a high mathematical expectancy of winning. Most casinos don’t lose money playing any particular game, and their big-winners often receive extravagant inducements such as free drinks, cigarettes, and reduced-fare transportation. Unlike most traditional gambling establishments, a casino will accept all bets within its limits.
The technology that makes casinos safe and efficient has increased dramatically over the past few decades. A casino’s employees are trained to keep the premises clean and safe. They are also equipped with video cameras and computers to monitor game play. One recent development in casino security is chip tracking, whereby each betting chip contains built-in microcircuitry to allow the casino to monitor the wagers of its patrons minute-by-minute. The casino’s roulette wheel is routinely monitored to ensure a reasonable statistical expectation of winning. In addition to video cameras and computers, some casinos have introduced “enclosed” versions of certain games, such as slots, that don’t require dealers and allow players to make bets by pushing buttons.
