A competition based on chance in which tickets are sold and prizes are awarded according to the results of random draws, often as a means of raising money for public or private enterprises. Lotteries are also popular with the media, where they are used to select contestants for television shows and sports teams.

Lotteries have been around a long time, as evidenced by keno slips from the Chinese Han dynasty, or even earlier, and by the casting of lots for everything from kingship to whether Jesus should keep his garments after the Crucifixion. In modern times, they’ve become a popular form of gambling, where people buy numbered tickets in the hope of winning large sums of money. They are a major source of revenue for state governments, although the costs of organizing and promoting them can subtract from the pool of available prizes.

Lotteries have been criticized for being addictive forms of gambling, but they can also provide people with the means to improve their lives. Lottery spending tends to rise during economic downturns, Cohen writes, as people are looking for a way to escape their troubles without having to raise taxes or cut services. But as they do so, they can end up worse off than before because the lottery robs them of their savings and erodes their financial stability. Those who do win the big prizes find themselves unable to control their spending habits and may find themselves struggling with addiction.
