Changes to the Mega Millions game matrix were introduced, meaning the jackpots will likely get bigger more often, and players have a better chance of winning the second-tier prize of $1 million (without the Megaplier). Certain states can now take advantage of the Just the Jackpot feature, which allows players to buy a ticket ($3 for two lines) that gives them a chance of winning the jackpot if they match 5 + 1, but no prizes if they match anything less than that.
Lotto America players are required to pick five main numbers from a range of 52, plus one Star Ball from a separate pool of 1 to 10. Alternatively, players can select the Quick Pick option to have Lotto America numbers randomly selected for them. Tickets costs $1 per line, but for an additional $1 players can also select an All Star Bonus option to have any non-jackpot prize multiplied - much like the Powerplay option in Powerball.

Unclaimed prizes are kept by the lottery jurisdiction. If a Grand Prize goes unclaimed, the money must be returned to all lotteries in proportion to their sales for the draw run. The lotteries then distribute the money, based on their own jurisdiction's laws, to other lottery games or to their jurisdiction's general fund, or otherwise as required by law.
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.
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.
