A casino is a gambling establishment where people wager money on games of chance. The casino’s advantage over players is mathematically determined and is known as the house edge. Casinos also take a percentage of all bets placed, which is called the rake. Many casino games involve some degree of skill, but most are entirely random. Some games, such as poker, allow players to interact with each other, but the casino still retains an edge.
Most casinos earn a large proportion of their income from slot machines and video poker, which are run by computer chips. The machines show varying bands of colored shapes rolling on reels (actual physical reels or an electronic representation of them) and when the right pattern appears, the player wins a predetermined amount. The machines are adjusted for optimal profit using a combination of house edge and variance, calculated by mathematicians and computer programmers known as gaming mathematicians or gaming analysts.
Some casinos are choosy about which customers they accept, and they focus their investments on the high rollers who gamble for huge sums of money. These gamblers are given special rooms and receive comps, or complimentary items, that can be worth tens of thousands of dollars. High rollers are also able to play in live tournaments, where the highest-stakes gamblers win a substantial prize.
Other casinos employ technology to help them maximize profits. Besides video cameras for security, some casinos use “chip tracking” to monitor betting chips with built-in microcircuitry and ensure that they are not moved while the game is in progress. Roulette wheels are electronically monitored regularly to discover any statistical deviation from expected results. And some casinos use automated systems to supervise table games, allowing them to oversee the exact amounts wagered minute-by-minute and warn croupiers of any suspicious activity.
Casinos are also staffed with employees who deal with customer complaints. Some casinos have hotlines for customers to call, while others have in-person complaint departments. Most casinos also have guest service representatives who are trained to assist guests with problems such as lost and stolen credit cards, room service issues, and billing questions.
