Two machines are used in each Mega Millions drawing. The model used for Mega Millions is the Criterion II, manufactured by Smartplay International of Edgewater Park, New Jersey. The balls are moved around by means of counter-rotating arms which randomly mix the balls. Individually, the five white balls, several seconds apart, drop through a hole in the bottom of the mixing drum.

In the United States, lotteries are run by 47 jurisdictions: 44 states plus the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Lotteries are subject to the laws of and operated independently by each jurisdiction, and there is no national lottery organization. However, consortiums of state lotteries jointly organize games spanning larger geographical footprints, which in turn, carry larger jackpots. Two major lottery games, Mega Millions and Powerball, are both offered in nearly all jurisdictions that operate lotteries, and serve as de facto national lotteries.
Lottery winners can choose to receive the money in either an annuity — annual allotments over 30 years — or to get it all at once in a single payment for a smaller amount. For example, the lump sum on the $502 million jackpot would be $301 million, according to lottery site USAMega.com. If a single winner takes the single payment, the federal tax withholding would be over $75 million. Then, there are state taxes too.
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.
