Gambling | Definition, History, Games, & Facts (2024)

gambling, the betting or staking of something of value, with consciousness of risk and hope of gain, on the outcome of a game, a contest, or an uncertain event whose result may be determined by chance or accident or have an unexpected result by reason of the bettor’s miscalculation.

The outcomes of gambling games may be determined by chance alone, as in the purely random activity of a tossed pair of dice or of the ball on a roulette wheel, or by physical skill, training, or prowess in athletic contests, or by a combination of strategy and chance. The rules by which gambling games are played sometimes serve to confuse the relationship between the components of the game, which depend on skill and chance, so that some players may be able to manipulate the game to serve their own interests. Thus, knowledge of the game is useful for playing poker or betting on horse racing but is of very little use for purchasing lottery tickets or playing slot machines.

A gambler may participate in the game itself while betting on its outcome (card games, craps), or he may be prevented from any active participation in an event in which he has a stake (professional athletics, lotteries). Some games are dull or nearly meaningless without the accompanying betting activity and are rarely played unless wagering occurs (coin tossing, poker, dice games, lotteries). In other games betting is not intrinsically part of the game, and the association is merely conventional and not necessary to the performance of the game itself (horse racing, football pools). Commercial establishments such as casinos and racetracks may organize gambling when a portion of the money wagered by patrons can be easily acquired by participation as a favoured party in the game, by rental of space, or by withdrawing a portion of the betting pool. Some activities of very large scale (horse racing, lotteries) usually require commercial and professional organizations to present and maintain them efficiently.

Prevalence of principal forms

A rough estimate of the amount of money legally wagered annually in the world is about $10 trillion (illegal gambling may exceed even this figure). In terms of total turnover, lotteries are the leading form of gambling worldwide. State-licensed or state-operated lotteries expanded rapidly in Europe and the United States during the late 20th century and are widely distributed throughout most of the world. Organized football (soccer) pools can be found in nearly all European countries, several South American countries, Australia, and a few African and Asian countries. Most of these countries also offer either state-organized or state-licensed wagering on other sporting events.

Betting on horse racing is a leading form of gambling in English-speaking countries and in France. It also exists in many other countries. Wherever horse racing is popular, it has usually become a major business, with its own newspapers and other periodicals, extensive statistical services, self-styled experts who sell advice on how to bet, and sophisticated communication networks that furnish information to betting centres, bookmakers and their employees, and workers involved with the care and breeding of horses. The same is true, to a smaller extent, of dog racing. The emergence of satellite broadcasting technology has led to the creation of so-called off-track betting facilities, in which bettors watch live telecasts at locations away from the racetrack.

Casinos or gambling houses have existed at least since the 17th century. In the 20th century they became commonplace and assumed almost a uniform character throughout the world. In Europe and South America they are permitted at many or most holiday resorts but not always in cities. In the United States casinos were for many years legal only in Nevada and New Jersey and, by special license, in Puerto Rico, but most other states now allow casino gambling, and betting facilities operate clandestinely throughout the country, often through corruption of political authorities. Roulette is one of the principal gambling games in casinos throughout France and Monaco and is popular throughout the world. Craps is the principal dice game at most American casinos. Slot and video poker machines are a mainstay of casinos in the United States and Europe and also are found in thousands of private clubs, restaurants, and other establishments; they are also common in Australia. Among the card games played at casinos, baccarat, in its popular form chemin de fer, has remained a principal gambling game in Great Britain and in the continental casinos most often patronized by the English at Deauville, Biarritz, and the Riviera resorts. Faro, at one time the principal gambling game in the United States, has become obsolete. Blackjack is the principal card game in American casinos. The French card game trente et quarante (or rouge et noir) is played at Monte-Carlo and a few other continental casinos. Many other games may also be found in some casinos—for example, sic bo, fan-tan, and pai-gow poker in Asia and local games such as boule, banca francesa, and kalooki in Europe.

At the start of the 21st century, poker exploded in popularity, principally through the high visibility of poker tournaments broadcast on television and the proliferation of Internet playing venues. Another growing form of Internet gambling is the so-called betting exchanges—Internet Web sites on which players make wagers with one another, with the Web site taking a small cut of each wager in exchange for organizing and handling the transaction.

In a wide sense of the word, stock markets may also be considered a form of gambling, albeit one in which skill and knowledge on the part of the bettors play a considerable part. This also goes for insurance; paying the premium on one’s life insurance is, in effect, a bet that one will die within a specified time. If one wins (dies), the win is paid out to one’s relatives, and if one loses (survives the specified time), the wager (premium) is kept by the insurance company, which acts as a bookmaker and sets the odds (payout ratios) according to actuarial data. These two forms of gambling are considered beneficial to society, the former acquiring venture capital and the latter spreading statistical risks.
