Gambling is the betting of money on an outcome that is wholly or largely random. It includes things like bingo, roulette, raffles, lotteries, scratch-cards and slot machines. Some definitions of gambling would not include activities like betting on horse racing – as this arguably involves a large element of knowledge and skill to predict what is likely to happen. Card games are a grey area. Some card games, such as poker, have a considerable element of skill. It is therefore arguable that they should not be considered gambling.
Other card games are largely a matter of luck. The precise legal definition of gambling varies from country to country. Most countries regulate gambling but there are still a few who do not, such as Costa Rica, who do not regulate the offshore licenses for gambling that they provide. For states such as the UK and Gibraltar who do regulate gambling, it is often necessary to have a license to run a lottery or a casino. There is also usually a minimum age for gambling.
Gambling is illegal in some jurisdictions, including several states of the USA, most regions of Russia and many Islamic countries. In contrast, some governments try to use gambling as a force for good. Many states run lotteries the profits are used to pay for public services. Charities and nonprofit organizations often hold bingo nights or lotteries to fund-raise. In the USA Native American nations control their own affairs and often profit by being able to run casinos on reservations, attracting gamblers from surrounding states where gambling is banned.
The rise of online gambling on the internet since the 1990s has made government control much harder. In some countries like the USA, online gambling is against the law. But in many states online gambling is now legal. And companies can set up in any country where online gambling is allowed, and offer a service to internet users all over the world. Many people who never bet on a race or visited a casino now gamble online. All of this new activity worries campaigners against gambling, as well as governments who feel that their control is being lost.
