The January 4, 2011 Mega Millions drawing drew attention for its similarity to "The Numbers," a sequence of six numbers that served as a plot device of the ABC drama series Lost. One such usage involved character Hugo "Hurley" Reyes playing the sequence in a similar "Mega Lotto" game, winning a nine-figure jackpot and subsequently experiencing numerous misfortunes in his personal life. The first three numbers (4, 8, 15) and mega ball (42) in the Mega Millions drawing matched the first three numbers and the final number (which Hurley also used as the "mega ball" number) in the Lost sequence. The last two numbers in the Mega Millions drawing did not match the last two numbers that were used in the scene. Those who played "The Numbers", including from quick-picks, won $150 ($118 in California) in a non-Megaplier game; $600 with the multiplier.
Mega Millions' second-largest jackpot, $648 million, was for the December 17, 2013 drawing. Two winning tickets, one each from California and Georgia, were sold. The holder of the Georgia ticket claimed the next morning; they selected the cash option, which amounted to $173,819,742.50 before withholdings. The holder of the California ticket claimed on January 3, 2014. (The California ticket holder received an equal share, but potentially a larger cash-option amount, as California lottery winnings are exempt from state income tax)." 
On Jan 31, 2010, the date of the cross-sell expansion, Mega Millions and MUSL each added lotteries; eight Powerball members added Mega Millions by May. The Montana Lottery joined Mega Millions on March 1. Nebraska added Mega Millions on March 20; Oregon followed on March 28; Arizona joined Mega Millions on April 18; Maine added Mega Millions on May 9; Colorado and South Dakota joined Mega Millions on May 16. The U.S. Virgin Islands joined Mega Millions in Oct 2010.
And of course, if non-US residents are eligible to buy the tickets, they are also eligible to claim the prize money should they win. However, be aware that the rules covering taxes and withholding vary depending on where you live. Countries outside of the United States might have different procedures. If you do win, be sure to consult with a tax professional for more information.
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 structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
