A casino is an establishment that accepts bets from patrons, as long as those bets are not higher than the bankroll of the casino. The house edge in a casino can be as low as two percent, but it can be much higher, with many games offering an advantage to the casino. In addition, casinos don’t need to cheat or change their game settings to gain an advantage over their patrons. Instead, they rely on the greed of their patrons to earn their money.
Technology has made casino gaming safer. In the early 1990s, video cameras and computers began to monitor games. “Chip tracking” involved betting chips with built-in microcircuitry, allowing casinos to monitor wagers minute-by-minute. Roulette wheels are also regularly monitored for statistical deviations. Lastly, enclosed versions of games were developed. Players no longer needed a dealer, and instead pressed buttons to bet. This increased security for patrons and helped casinos increase their profit margins.
Casino security is essential in the case of a robbery. In addition to being well-lit, casinos are equipped with surveillance systems. One such innovation is catwalks that run through the ceilings above the casino floor. The catwalks have one-way glass, which makes them easier to detect if a robber is trying to break into a casino. Although it’s still not 100% fool-proof, these methods are becoming more popular as casinos are becoming a luxury for many people.
