Lotteries are government-sponsored games of chance where participants pay a small fee to have the opportunity to win a prize. They are a common form of gambling in many countries. They may take the form of a simple raffle, a drawing for prizes, or a game of chance with a fixed prize pool. The prizes may be money, goods or services. Many governments regulate lottery games and enforce anti-fraud laws. The profits from lotteries are often used to support public services and social welfare programs. The popularity of the lottery has increased with the advent of the Internet and mobile phones. It has also become possible to play lottery-style games online, with the winnings typically being deposited in an account, rather than given to the winner in cash.

Until 1967 buying a lottery ticket was illegal in Canada. That year the federal Liberal government introduced an Omnibus Bill intended to update a number of obsolete laws. The bill included an amendment allowing provincial and territorial governments to operate a lottery system. Montreal Mayor Jean Drapeau took advantage of the opportunity and in September 1968 announced a “voluntary tax.” Players would pay $2.00 to participate in a lottery draw for silver bars that were worth more than $100,000. There were debates in Ottawa and Quebec City about the legality of this , but Drapeau was able to convince the provincial court that his lottery did not contravene the existing law.

In Vietnam, where the social security systems are not yet able to handle the amount of poor citizens, selling lottery tickets is a very common way for people to earn an income. Often, as in the case of Huong, a pregnant mother from Saigon, lottery tickets are their only means to survive. On good days she sells 250 tickets a day, earning a profit of about 11 US-Dollars. On bad days she sells 180. Her husband Manh has to accompany her during the heavy 16-hour shift of selling lottery tickets.

In New Zealand, the National Lottery is a Crown entity that controls four lottery games: Lotto 6/49, Lotto Max (which replaced Lotto Super 7 in September 2009), Daily Grand, and Millionaire Life. Lottery proceeds are distributed by the New Zealand Lottery Grants Board to a number of charitable and community organizations. These include Sport and Recreation New Zealand, Creative New Zealand, and the Arts Council of New Zealand. In addition, the lottery is administered by an Interprovincial Lottery Corporation consortium of the five regional lotteries: Atlantic Lottery Corporation (New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador), Loto-Quebec (Quebec), Ontario Lottery and Gaming Corporation (Ontario), and Western Canada Lottery Corporation (Manitoba, Saskatchewan, Alberta, Yukon, Northwest Territories, and British Columbia). Unlike most countries, there are no private lotteries in New Zealand.
