What is a Lottery?

Lottery is a game in which players purchase tickets for a drawing of prizes ranging from small cash amounts to life-changing jackpots. The casting of lots for decisions and fates has a long history, including several instances in the Bible, but lottery games intended to generate substantial material gain have been around much more recently. Some of the founding fathers ran them: Benjamin Franklin organized one to raise money for cannons to defend Philadelphia, and Thomas Jefferson hoped to alleviate his crushing debts by running a private lottery.

Once established, state lotteries resemble most other businesses in their market orientation: they compete for players by offering a variety of products that reflect the preferences and demographics of the population. The resulting competition, in turn, drives innovations in the game itself. Lotteries often start with a modest number of relatively simple games, then increase their size and complexity. They may add new categories of tickets, such as scratch-offs, or introduce new ways to play existing ones, such as a prize payout that is proportional to ticket sales.

Many, but not all, lottery websites display information about ticket demand. For example, some states list the total number of tickets purchased by all buyers, the number of winners, and other statistics. Some also report on the percentage of the total prize pool that is paid out, as well as the amount of winnings for specific dates and games. The disposition of unclaimed prizes varies from lottery to lottery, but most allow the proceeds to reenter the prize pool for future games.
