Based on statistical projections, the average jackpot win increased from $95 million to $141 million. Over 3.5 million additional prizes were expected to be won yearly due to the change in probability. The starting jackpot increased to $20 million, with minimum rollovers of $5 million. The jackpot contribution increased from 30.3% to 32.5% of total sales. The Power Play option was modified; second prize, usually $200,000, was given an automatic 5x multiplier, making the 5+0 prize $1 million cash. The bonus second prize if the jackpot exceeded its previous record by $25 million, triggered only twice, was eliminated with the 2012 format change.
The New Jersey Lottery, among others, in early 2009 announced it would seek permission to sell Powerball tickets alongside Mega Millions. In October 2009, an agreement between Mega Millions and MUSL allowed all U.S. lotteries, including New Jersey's, to offer both games. On January 31, 2010, Mega Millions expanded to include the 23 MUSL members; as of that date, 35 jurisdictions were participating in Mega Millions. On the same day, 10 existing Mega Millions-participating lotteries began selling Powerball tickets. Ohio joined Powerball on April 16, 2010. On March 1, 2010, Montana became the first MUSL member to add Mega Millions after the cross-sell expansion. Nebraska became the 37th Mega Millions participating member on March 20, 2010, followed by Oregon as the 38th member on March 28, Arizona as the 39th member on April 18, and Maine as 40th Mega Millions participant on May 9, 2010. Colorado and South Dakota added Mega Millions on May 16, 2010, bringing the total to 42 jurisdictions.
In spite of the huge popularity of this lottery draw game it is still an unknown to many that you can buy Powerball tickets online, whether you are in the US or not. To be clear, this doesn’t even mean that you have to be a citizen of the US either. No citizenship & not based in the US? You can still play powerball online and buy lottery tickets online for a number of different lottery draw games.
