The final 5/56 + 1/46 Mega Millions drawing was held on October 18, 2013; that night's jackpot of $37 million was not won. The first drawing under the revised 5/75 + 1/15 format—which saw the jackpot estimate "leap" to $55 million due to the change in the annuity structure—occurred on October 22, 2013. The minimum jackpot was then $15 million, with rollovers of at least $5 million. Second prize (5+0) became $1 million cash. In the revised format, players chose 5 of 75 white ball numbers, and the "Gold Ball" number out of 15.
Never choose all odd or all even numbers. Such combinations (either all ‘odd’ numbers, or all ‘even’ numbers) make up only 3% of prizes won. Most winning Mega Millions tickets are notable for having three ‘odd’ and two ‘even’ numbers. Alternatively, you could choose three ‘even’ numbers and two ‘odd’ numbers, although your chances to win won’t be quite as good. The mega-ball number can be either an ‘even’ or an ‘odd’ number, and is not related in any way to your main (white) ball choices.
On June 2, 2010, Ohio won a Powerball jackpot; it became the first lottery selling either Mega Millions or Powerball (when 2010 began) to provide a jackpot-winning ticket for its newer game. The ticket was worth a $261 million annuity; it was sold in Sunbury. Ohio's second Powerball jackpot-winning ticket, sold for the June 23, 2010 drawing, was part of another first; since Montana also provided a jackpot winner for that drawing, it was the first time a jackpot was shared through lotteries which sold competing games before the cross-selling expansion, as Montana sold only Powerball before the expansion date.
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.
This method specifically has faced criticism recently from a number of lottery organizers such as Camelot, the UK National Lottery organizers who are not happy with companies “selling tickets” (selling bets on outcomes of their established lottery draws) for prices sometimes even cheaper than Camelot themselves sells their tickets. This legal and corporate dispute looks set to continue for the foreseeable future, in the mean time you can continue to buy Powerball tickets online, only now you are aware of the key differences between the two business models.
