Lottery games, also known as the national lottery or state lottery, are a form of gambling that awards prizes to players according to a random process. They may be operated by a government agency, private business, or a combination of both. In the United States, most lotteries are run by state governments. They are a popular way to raise funds for public projects, such as schools or hospitals. Some states also allow players to purchase tickets online or through telephone or radio programs.

Lotteries have been around for centuries. In the earliest times, they were simple drawings for small prizes. But in the late 20th century, a variety of innovations gave rise to many modern lotteries. These include instant tickets, keno, and video lottery terminals (slot machines in all but name). Despite their popularity, not all states have legalized or regulate them.

Some countries have state-run lotteries, while others permit only private-sector operators. In the United States, state-run lotteries are typically run by a gaming commission and use proceeds to support governmental agencies such as education or public health. Private companies that operate lotteries in other countries, such as Camelot Group in the UK, often have their operations regulated by national regulators.

A state-run lottery is an important source of revenue for many governments, especially those that do not collect taxes. In the United States, most of the money raised by state-run lotteries goes to education. The rest is divided among other state and local purposes. A few states, notably California and Florida, have separate lotteries for other purposes.

In addition to state-run lotteries, many countries have regional or provincial lottery corporations that organize and sell games of chance. For example, in Canada, the provincially-owned Lottery Corporation manages four national lotteries: Lotto 6/49, Lotto Max, Daily Grand, and Millionaire Life. In the US, a number of private-sector lottery organizations operate lotteries under licence from state governments.

For many poor people in Vietnam, selling lottery tickets is their only means of making a living. Since their social security systems are not yet able to handle this number of needy citizens, they choose to sell tickets rather than perform the socially-detested act of begging on the street. On good days, a lottery ticket seller can earn about 250 000 VN-Dong (about 11 US-Dollars) per day. On bad days, their profits fall to 180 000 VN-Dong. These are not high earnings, but they give them enough money to survive. Their daily routine starts early, at 5 am. They prepare a simple breakfast of rice and vegetable soup before hitting the streets. Then they work a heavy 16-hour shift, sometimes even all night long. They rely on their earnings to provide for themselves and their families.
