Lottery is a form of gambling in which people buy chances to win cash or goods. Lottery profits are often donated to good causes.

The word lottery is derived from the Latin term lotto, meaning “to divide by lots.” It is believed that the first European public lottery was organized in 15th-century Burgundy and Flanders with the purpose of raising money for fortifications or relief for the poor. Francis I of France introduced a nationwide public lottery system in the 16th century.

Most states organize their own lotteries and delegate responsibility for regulating them to a state-run agency called a lottery division. The lottery division typically selects and trains retailers to use lottery terminals, enlists the help of advertising agencies to promote the lottery, and manages the distribution and payment of prizes to winners. Some states also have special lotteries for a limited number of high-tier prizes, such as units in subsidized housing or kindergarten placements at a prestigious school.

A large percentage of the money from a lottery is paid out in prize funds to winning ticket holders, with the remainder going to support the running costs of the operation. Some states also keep some of the money for a reserve fund to cover the cost of future prizes, a practice known as a surplus prize account.

Although some people may believe that they can improve their life prospects by purchasing a lottery ticket, most experts agree that the odds of winning are extremely long and there is no guarantee that any particular ticket will be a winner. Lotteries are based on the human desire to dream big and the illusion that money can solve problems (despite the biblical prohibition against coveting what belongs to others; see Ecclesiastes 5:10).
