One of the first rules of a casino is that there are no clocks. This would be a dangerous practice since it could easily set off a fire. Instead, casinos use bright and gaudy wall and floor coverings to create an upbeat and stimulating atmosphere. The colors of the casino are typically red or blue. This color has the unintended consequence of causing gamblers to lose track of time, so casinos do not have clocks in their establishments.
In the 1990s, casinos began to use technology to improve the quality of customer service and the quality of their games. For example, casinos regularly monitor the performance of their blackjack tables using video cameras. Some of the most sophisticated roulette wheels now have microcircuitry built into them, which helps casinos track the wagers minute-by-minute. This allows casinos to make informed decisions about the payouts. Enclosed versions of some games also allow players to place bets by pushing buttons instead of dealing with dealers.
American residents’ education level also varies from state to state. In 1989, the median age of Americans who visited a casino was 22 years old, and that number was just the same in 2008. Today, 24% of Americans have a graduate degree or some college credits, and nearly half have never attended college. The average level of education is not much different compared to the national average, but the data does indicate that Americans are more likely to visit a casino than they were in 1989.
