The US Powerball game, arguably one of the most popular and widely-played games in the United States, is a shared jackpot game which is co-ordinated by an NPO formed by an agreement between the various state lotteries. The US Powerball game has become renowned for its impressive $40 million starting jackpot, with the potential of yielding nine-figure jackpot wins.
Mega Millions' second-largest jackpot, $648 million, was for the December 17, 2013 drawing. Two winning tickets, one each from California and Georgia, were sold. The holder of the Georgia ticket claimed the next morning; they selected the cash option, which amounted to $173,819,742.50 before withholdings. The holder of the California ticket claimed on January 3, 2014. (The California ticket holder received an equal share, but potentially a larger cash-option amount, as California lottery winnings are exempt from state income tax)." 
Since the secondary prizes are defined in fixed amounts (except in California), if the liability for a given prize level exceed the funds in the prize pool for that level the amount of the prize may be reduced and the prize pool be distributed on a parimutuel basis and result in a prize lower than the fixed amounts given in the prize tables. Because the secondary prize pools are calculated independently, it is possible lower-tier prizes will differ among the game members.
On March 13, 2010, New Jersey became the first previous Mega Millions-only member (just before the cross-selling expansion) to produce a jackpot-winning Powerball ticket. It was worth over $211 million in annuity payments; it was sold in Morris Plains. On May 28, 2010, North Carolina became the first previous MUSL member (just before the cross-selling expansion) to produce a jackpot-winning Mega Millions ticket; that jackpot was $12 million (annuity).
The structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
