^ Jump up to: a b Prizes are uniform in all Mega Millions jurisdictions, with the exception of California (where all prizes, including the jackpot, are pari-mutuel; payouts are based on sales and the number of winners of each prize tier.) All other Mega Millions members' second through ninth prizes are set amounts, although in rare cases they can be reduced.

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.


Unlike Hot Lotto, which used a random number generator during most of its run (including the December 2010 drawing whose jackpot was "won" by Eddie Tipton, a MUSL employee), Lotto America is drawn using physical ball machines and numbered balls. One machine draws the five main numbers while another is used to draw the "Star Ball". As of September 1, 2018, none of these drawings have been made available to the viewing public; these drawings are believed to be held in Tallahassee, Florida, even though Florida does not participate in the game.[5]

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 minimum jackpot prize is a $15 million annuity disbursed in 30 payments over 29 years which is something many people would elect to do.The 30 annuity payments are not equal but based on an increasing rate schedule. For example, the first annual gross annuity payment on the base $15 million jackpot would be approximately $267,000 while the final payment would be approximately $834,000.

The probability and odds can be taken into a mathematical perspective: The probability of winning the jackpot (through October 27, 2017) was 1:(75C5) x (15); that is: 75 ways for the first white ball times 74 ways for the second times 73 for the third times 72 for the fourth times 71 for the last white ball divided by 5 x 4 x 3 x 2 x 1, or 5!, and this number is then multiplied by 15 (15 possible numbers for the "Megaball"). Therefore, (75 x 74 x 73 x 72 x 71)/ (5 x 4 x 3 x 2 x 1) x 15 = 258,890,850, which means any combination of five white balls plus the Megaball has a 1:258,890,850 chance of winning the jackpot. Similarly, the odds for second prize are 1:(75C5) x (15/14) = 1: 18,492,204 chance of winning. The overall probability of winning any prize was 1 in 14.7. If there are no jackpot winners for a specific drawing, the jackpot will keep increasing, however, the odds will still remain the same.
The two different methods, both offer you, the player, the same user experience and the only difference is in the back end of how the online lottery ticket provider works. The two methods that online lottery sites use differ in one key way; They either have agents and employees all over the world that physically purchase tickets on behalf of clients or, the more recent phenomenon is when companies essentially take out an insurance policy on every ticket which is tied to the size of the jackpot. This is the difference between you playing the lottery online and betting on the lottery online*. In the latter option you are, de facto, not playing the US Powerball online but rather you are placing a bet with an insurance company on the outcome of the corresponding Powerball draw.
