You do not have to be a U.S. citizen or U.S. resident to play Powerball®. Players from jurisdictions where Powerball tickets are not sold, either in the United States or outside the country, can purchase Powerball tickets from a retailer licensed or authorized by the selling jurisdiction, if they meet the legal age requirement in the jurisdiction of purchase. Federal and jurisdictional income taxes may apply to any claimed prize money.
The Euro Jackpot results are comprised of seven numbers, 5 regular balls chosen from the numbers 1 to 50 and the two special Euro Balls which are chosen from the numbers 1 to 10. Matching all of the numbers on your Betslip wins you the multi-millionaire jackpot but there are 11 other smaller tiers which you should also check as just matching two numbers correctly will win you the minimum prize. Simply click on a result and this will produce a full prize breakdown for all of the different tiers. Good luck!
Drawings for Powerball are held every Wednesday and Saturday evening at 10:59 p.m. Eastern Time. Since October 7, 2015, the game has used a 5/69 (white balls) + 1/26 (Powerballs) matrix from which winning numbers are chosen, resulting in odds of 1 in 292,201,338 of winning a jackpot per play.[1] Each play costs $2, or $3 with the Power Play option. (Originally, Powerball plays cost $1; when PowerPlay began, such games were $2.) The official cutoff for ticket sales is 10:00 p.m. Eastern Time; some lotteries cut off sales earlier.[2] The drawings are usually held at the Florida Lottery’s studio in Tallahassee.
The minimum Powerball bet is $2. In each game, players select five numbers from a set of 69 white balls and one number from 26 red Powerballs; the red ball number can be the same as one of the white balls. The drawing order of the five white balls is irrelevant; all tickets show the white ball numbers in ascending order. Players cannot use the drawn Powerball to match two of their white numbers, or vice versa. Players can select their own numbers, or have the terminal pseudorandomly select the numbers (called "quick pick", "easy pick", etc.).
In March 2009, it was reported that New Jersey, already a Mega Millions member, sought permission to join Powerball. Shortly after, discussions were revealed about allowing each US lottery to offer both games. On Oct 13, the Mega Millions consortium and MUSL reached an agreement in principle to cross-sell Mega Millions and Powerball.[9] In Nov, MUSL signed an agreement to start streaming Powerball drawings online.[10][11]
A Powerball jackpot winner may choose to receive their prize in 30 payments over 29 years or a lump-sum payment. The cash value option, in general, is the amount of money required to be in the jackpot prize pool, on the day of the drawing, to fund the estimated jackpot annuity prize. The advertised jackpot annuity and cash value are estimates until ticket sales are final, and for the annuity, until the Multi-State Lottery Association takes bids on the purchase of securities. 
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.
