Before the advent of government-sponsored lotteries, many illegal lotteries thrived, such as number games. The first modern government-run US lottery was established in Puerto Rico in 1934. This was followed, decades later, by the New Hampshire lottery in 1964. Instant lottery tickets, also known as scratch cards, were introduced in the 1970s and have become a major source of lottery revenue. Individual lotteries often feature three-digit and four-digit games akin to numbers games; a five number game, and a six number game (the latter two often have a jackpot.) Some lotteries also offer at least one game similar to keno, and some offer video lottery terminals. Presently, many US lotteries support public education systems.
Another study looked at winners. In 2015, the Maine Department of Health and Human Services analyzed data from the Bureau of Alcohol and Beverage and Lottery Operations on individuals who won money in the state lottery. Some 4,865 winning tickets of $1,000 or more were cashed in by 3,685 individuals receiving state benefits over the previous five years, reaching $22 million in lottery jackpots of various sizes. So — unless they were an unusually lucky group of people — they likely spent far more than any other group on tickets.
