One of the most interesting facts about casinos is that they have no clocks or windows. This is an intentional design element, as clocks are a fire hazard. Rather, casinos use gaudy colors on walls and floor coverings, which have a cheering and stimulating effect. Many of the casino’s staff members are intoxicated, which can impair one’s judgment when betting. Therefore, they hire outside experts to do this work.

Aside from accepting all bets within a set limit, casinos cannot lose money. Every game they offer has a mathematical expectation of winning, so they seldom lose money. This is one of the reasons why casinos frequently offer big-betting gamblers extravagant inducements, such as reduced-fares transportation. Moreover, the gambling establishments also give out free cigarettes and drinks to their patrons. Aside from these inducements, casinos are also known to have high turnover rates and a high payout percentage.

As the casino industry became more advanced, so did its technology. Nowadays, video cameras and computers are routinely used to supervise all games. “ChiP tracking” is a new technology whereby the casino tracks betting chips minute-by-minute. This technology has also allowed casinos to monitor roulette wheels for statistical deviations. In addition, some casinos now offer enclosed versions of their games, where players bet using a button instead of a dealer.
