Lotteries are a form of gambling. They can be legal or illegal, depending on the jurisdiction. Typically, lotteries are used to fund educational programs, public projects, and for a variety of other reasons.

Lotteries are played in more than 100 countries around the world. Some governments promote them, while others outlaw them. The earliest recorded European lottery was held in the Roman Empire.

A few colonies used lotteries to finance local militias, fortifications, and other public projects. Several states also used them to raise funds for colleges and libraries.

Unlike other forms of gambling, lottery tickets are not necessarily paid out in one lump sum. Instead, winners receive either an annuity payment or a single payment.

Depending on the jurisdiction, lottery tickets can be purchased at a local store or online. A few jurisdictions have limits on how much a person can spend on a ticket. Others restrict the age of persons who can purchase tickets.

Most of the United States operates a number of online lotteries. Washington DC, Puerto Rico, and the Virgin Islands operate lotteries when 2021.

In addition to the traditional lottery products, a few online lotteries are expanding their service offerings to include Instant Games. These are casino-like games that can be played from a desktop or smartphone. Several companies, including GTech and IWG/NeoPollard, provide these services.

A handful of Northeastern states, including New Jersey, Massachusetts, and Rhode Island, are in the process of legalizing their own online lottery programs.
