Modern casinos are indoor amusement parks for adults. While they may not have traditional attractions like amusement park rides, they are largely dependent on gambling. In fact, many casino owners and operators try to keep slot players happy by lowering their “house edge.” This refers to the advantage the casino has over the player over the long run when comparing wagers and payouts. For example, if the house edge is 5%, the casino will benefit twice as much over the long term as if the house edge was 10%.

Today, casinos have become more sophisticated and discerning, concentrating their attention on the highest-stakes players. They have separate high-limit rooms for high rollers and offer five-star food and drinks for these patrons. Their profits are enormous, and their incentive programs often include lavish inducements like free drinks and cigarettes for big bettors. However, these incentives aren’t enough to keep the casino’s doors open to everyone.

To ensure fair play and avoid cheating, casinos have embraced new technology to monitor the games and make the environment safer. Computers and video cameras routinely oversee game play. A new technology called “chip tracking” enables casinos to monitor wagers minute by minute. Roulette wheels are regularly monitored for statistical deviations. The casino industry has also introduced enclosed versions of many of its games, which don’t require dealers, and let players bet simply by pressing buttons.
