Presumably due to their experience with the Power Play option for Powerball, all 23 lotteries joining Mega Millions on January 31, 2010 immediately offered Megaplier to their players. The Megaplier continues to be drawn by Texas Lottery computers, as California does not offer the multiplier. Montana, offering Powerball before the expansion date, became the 24th lottery to offer the Megaplier, followed by Nebraska (the 25th), Oregon (the 26th), Arizona (as the 27th) and Maine (as the 28th lottery to offer the Megaplier option). After Colorado and South Dakota joined Mega Millions, this raised the number of lotteries offering the Megaplier to 37.

In March 2009, it was reported that New Jersey, already a Mega Millions member, sought permission to join Powerball. Shortly after, discussions were revealed about allowing each US lottery to offer both games. On Oct 13, the Mega Millions consortium and MUSL reached an agreement in principle to cross-sell Mega Millions and Powerball.[9] In Nov, MUSL signed an agreement to start streaming Powerball drawings online.[10][11]


Players who match five numbers from the first pool win $1 million; those matching four numbers from the first pool and the Gold Mega Ball number win $10,000; those matching four numbers from the first pool win $500; those matching three numbers from the first pool and the Gold Mega Ball win $200; those matching two numbers plus the Gold Mega Ball win $10; those matching one number and the Gold Mega Ball win $4; and those matching only the Gold Mega Ball win $2.
Having initially played 'little sister' to Mega Millions, changes made to Powerball in January 2012 and October 2015 meant that the Powerball lottery now consistently awards the biggest lottery jackpots in the world. In the year after the 2012 changes just under one in two (actual amount: 50 out of 104) Powerball draw jackpots were more than $100,000,000.
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).
These changes were made to increase the frequency of nine-figure jackpots; a Powerball spokesperson believed a $500 million jackpot was feasible (it became a reality within the year,[15]) and that the 1st $1 billion jackpot in US history would occur by 2012[16] Less than three months after the Powerball changes, Mega Millions' jackpot reached $656,000,000 despite remaining a $1-per-play game.[17] The random Power Play multiplier was retired for a set, fixed dollar amount payout.[18] The $25 million rollover "cap" (creating larger 5+0 prizes) was eliminated.
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.
