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 American Powerball lottery makes use of two machines drawing two sets of numbers. In this way, it is similar to other lotteries like the Mega Millions and EuroMillions. Powerball players need to match five numbers from a possible 69 (these are the white numbers), and one number from a possible 26 (these are the red bonus ‘Powerballs’). If a player matches up all six numbers that have been drawn, they will win the jackpot. Second tier division winners have a $1 million prize to look forward to – one does not even need to match all six numbers in order to become a millionaire with the US Powerball game!

The North American Association of State and Provincial Lotteries dispute the findings of these various studies. Lottery retailers are located in areas where people work, not just in low-income neighborhoods, along with grocery stores, the organization says. This is why you will find more lottery outlets in the center of a city, just as you would find more grocery stores and convenience stores, the NASPL adds. Since the New Hampshire lottery was founded in 1964, according to the NASPL, it says lotteries have raised more than $200 billion for government programs in North America.

On January 13, 2016, the world's largest lottery jackpot, an annuity of approximately $1.586 billion, was split among three Powerball tickets in Chino Hills, California, Melbourne Beach, Florida and Munford, Tennessee, each worth $528.8 million. Since there is no income tax in Florida or Tennessee (and California does not tax lottery winnings), the cash option after Federal withholdings is $187.2 million each.[32]
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.

The odds of winning the Mega Millions jackpot are 1 in 302.6 million, making them the highest odds of any other state or multi-state lottery game ever played in the United States. However, this means the jackpot can grow to surpass the billion-dollar mark with relative ease. The overall odds of winning any prize are 1 in 24, which is slightly better than that of Powerball, which are 1 in 24.87.
The only way to be sure that what you are buying is “official” is to purchase your tickets from a company that has agents that will purchase in the real world the Powerball tickets online that you have selected. If you are a more trustworthy person and don’t need a scanned copy of your Powerball tickets online then by all means go for an online lottery ticket provider that follows the insurance model. 

Some retailers that sit on state lines often offer both state lotteries with state boundaries clearly marked, since such sales still have to occur in the physical state it is offered. One retailer located along U.S. Route 62that is largely in Sharon, Pennsylvania but has a small portion lying inMasury, Ohio sells both the Ohio Lottery and the Pennsylvania Lotteryat one location. The first modern US joint-state lottery game was formed in 1985 inMaine, New Hampshire, and Vermont. In 1988, the Multi-State Lottery Association (MUSL) was formed with Iowa, Kansas, Missouri, Oregon,Rhode Island, West Virginia, and the District of Columbia as its charter members; it is best known for Powerball, which was designed to create large jackpots. Another joint lottery, The Big Game (now called Mega Millions), was formed in 1996 by six other lotteries as its charter members.
On January 13th, 2016 the American multi-state lottery Powerball set the world-record for the biggest jackpot of all time at USD$1.6 billion when it was won by John and Lisa Robinson of Tennessee, Maureen Smith and David Kaltschmidt of Florida and Marvin and Mae Acosta of California. It was the first time in history a prize had topped the billion dollar mark!

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.
Power Play, when it began in 2001, was drawn with a special wheel. In 2006 and 2007, MUSL replaced one of the 5× spaces on the Power Play wheel with a 10×. During each month-long promotion, MUSL guaranteed that there would be at least one drawing with a 10× multiplier. The promotion returned in 2008; the ball landed in the 10× space twice. After being absent in 2009, the 10× multiplier returned in May 2010 (after the Power Play drawing was changed to RNG.) The promotion was extended for the only time, as the 10× multiplier was not drawn until June 12. The second prize 5× guarantee continued; the 10× applied to all non-jackpot prizes, as in previous promotions.

Winning the jackpot requires matching all five numbers, plus the Powerball. Players who match five numbers win $1 million; players who match four numbers plus the Powerball win $50,000; players who match four numbers win $100; players who match three numbers plus the Powerball win $100; players who match three numbers win $7; players who match two numbers plus the Powerball win $7; players who match one number plus the Powerball win $4; and players who match only the Powerball win $4.
First introduced in 1996, the USA Mega Millions was originally known as ‘The Big Game’ - and looking at its payouts over the years, it’s no surprise as to why. With a starting jackpot of $40 million and a record jackpot of $656 million to date, winning the USA Mega Millions is no joke - although when you hit the big one you’ll be laughing all the way to the bank.
Jump up ^ "Mega Millions jackpot reaches record $500 million". Komo News. Sinclair Interactive Media. March 28, 2012. Retrieved September 4, 2013. The jackpot was originally announced at $476 million early Wednesday morning but rampant ticket sales boosted the estimated payout to the $500 million mark. Tuesday night's jackpot was $363 million, fed by weeks of drawings without a top winner. It has rolled 18 times since Marcia Adams of College Park won $72 million in the Jan. 24 drawing. A winner could get $19.2 million a year for 26 years or a single payment of $359 million. The previous record jackpot in the Mega Millions game was $390 million in 2007, split by two winners in New Jersey and Georgia.
