Lottery is a gambler’s game of chance, and it can be very lucrative. The odds of winning vary, but you can boost your chances by studying the math and playing a little strategy.

Lotteries are a popular source of state revenue, but I’ve never seen the percentage of total state revenues that they represent put into context. The general message seems to be that even if you lose, you should feel good because your ticket purchase supports the state.

The lottery is an old form of gambling that goes back centuries, from the Old Testament to Roman emperors giving away slaves and property. In the fourteenth century, it was a common way to distribute land in the Low Countries, and by the sixteenth century it had made its way to England, where Queen Elizabeth I chartered the first national lottery in 1567.

Despite Protestant proscriptions against gambling, public lotteries spread to America from England and became popular there. In the colonial period, they grew in popularity, and helped fund everything from town fortifications to schools. Harvard, Yale, and Princeton were all partly financed by lotteries, and the Continental Congress used one to try to raise funds for the Revolutionary War.

Americans spend more than $80 billion on lotteries every year, and it’s not surprising that most of them don’t understand the odds or how the games work. And they fall for a lot of quote-unquote systems that sound great but are based on bad statistical reasoning — like buying a certain type of ticket at a specific store, or choosing your numbers according to the time of day that you’re purchasing.
