Slots are the gambling machines that generate upward of three-quarters of casino revenue. They are also the lynchpin of campaigns to expand legalized gambling, and they entice individuals to become addicted to gambling three times more quickly than other games. [1]

Though poker, Texas Hold ’Em, and other card games receive more fanfare than slots, these devices are still the moneymakers of the casino business. They use principles of probability and chance to beguile players into putting up their cash for a chance to win big.

Historically, these machines have come under attack from forces of morality and law. Fey was able to circumvent these restrictions by requiring the purchase of a pack of gum in order to play a slot machine, and by designing machines that dispensed coins only after a player had completed a legal transaction (perhaps purchasing drinks or cigars at a saloon).

Modern casinos have made the move to electronic machines, replacing mechanical reels with video screens, buttons instead of handles, and accept players’ loyalty cards instead of cash. A number of new features have emerged, including multiple paylines and multipliers. In addition, video monitors and 3D graphics have brought a visual appeal to the gambling industry that was previously limited to table games like blackjack and poker.

Many people enjoy playing slots based on their favorite movies and TV shows. Often, these games are loaded with special features, such as cascading wins and complicated bonus systems. A careful review of the paytable, found in the information section of each slot machine, can help a player understand what to expect from a particular game before starting to play it.
