The Mega Millions is an American lottery game which is played in multiple jurisdictions across the country (and indeed, the world), with the first draw taking place in 2002. It also holds the proud title of giving off the third largest recorded lottery win in American history. In March 2012, a $656 million annuity value (cash value $474 million) jackpot was won and split three ways due to three winning tickets.

Powerball numbers are drawn from two sets of numbers, so the odds of winning a prize are calculated by combining the odds for both sets of numbers for all prize levels. The odds for matching just the Powerball are calculated by combining the odds of selecting the Powerball and the odds of not selecting any of the five numbers from the first set of numbers drawn.
When it was launched in 1992 Powerball became the first game to use two drums. Using two drums to draw numbers from offers more manipulation by simultaneously allowing high jackpot odds, numerous prize levels and low overall odds of winning (as explained later, a ticket can win by matching only one number). The two-drum concept was suggested by Steve Caputo of the Oregon Lottery. The two-drum concept has since been used by The Big Game (now Mega Millions) in the US, Australia's Powerball, Thunderball in the UK, Eurojackpot and EuroMillions (unlike most two-drum games, Euromillions selects two numbers called "Lucky Stars" from the 2nd drum; jackpot winners must make a total of seven matches).[citation needed]
The US Powerball is a standard lottery draw game based and operated from the golden State of California. The US Powerball has been making millionaires and multi-millionaires since its first drawing way back in 1992. With over 25 years of experience in the lottery industry, the Powerball, along with many other State lotteries, has broken through the final glass ceiling and transformed itself from an interstate lottery into a truly international lottery of global reach.
