A lottery is a game of chance in which numbers are drawn to win a prize. Lotteries are used to raise funds for a variety of public and private ventures. They are simple to organize and popular with the public. During the American Revolution, several colonies held public lotteries to help finance local militias. In the early United States, lotteries were often used to fund public projects such as roads, canals, bridges, and libraries. Private lotteries were also common. Some of the earliest public colleges were founded with lotteries, including Harvard, Dartmouth, Yale, King’s College (now Columbia), and William and Mary.

Despite their popularity, the purchase of lottery tickets cannot be accounted for by decision models based on expected value maximization. In fact, a lottery ticket has negative expected value, and people who purchase them are making a bad investment decision. Nevertheless, people continue to buy lottery tickets, perhaps because they enjoy the entertainment value of the gamble or because the prospect of becoming wealthy is appealing.

Those who want to maximize their chances of winning must understand the mathematical foundation of lottery strategy. While many lottery players rely on luck, successful winners use proven strategies to achieve their goals. Richard Lustig, a retired professor of economics, has won seven lottery grand prizes over the course of two decades. His method combines a clear understanding of probability with rigorous testing and meticulous practice.
