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. 
Lottoland is not an official lottery operator and does not buy any lottery tickets on your behalf. Instead, Lottoland allows you to make bets on different lotteries. If you win any bets, then you get paid directly by Lottoland and not the official lottery operator. All jackpots are estimates and subject to currency fluctuations. *Tier 1 winning bets on the US Powerball and US MegaMillions are paid out as 30 year annuity or discounted lump sum at Lottoland’s election, and Tiers 1 – 3 are also subject to 38% reduction as per T&C's. Tiers 1 - 3 for winning bets on SuperEnalotto are subject to 12% reduction as per T&C's.
Before the advent of government-sponsored lotteries, many illegal lotteries thrived, such as number games. The first modern government-run US lottery was established in Puerto Rico in 1934. This was followed, decades later, by the New Hampshire lottery in 1964. Instant lottery tickets, also known as scratch cards, were introduced in the 1970s and have become a major source of lottery revenue. Individual lotteries often feature three-digit and four-digit games akin to numbers games; a five number game, and a six number game (the latter two often have a jackpot.) Some lotteries also offer at least one game similar to keno, and some offer video lottery terminals. Presently, many US lotteries support public education systems.
Once your ticket is purchased, scanned and uploaded into your account that ticket is yours. Legally and in every other sense possible. The same questions always pop up at this stage of the explanation to new time online lottery players and these doubts can be best explained in further detail in the article on the Iraqi Lottery winner but the gist of it is as follows: 
Lotto America players are required to pick five main numbers from a range of 52, plus one Star Ball from a separate pool of 1 to 10. Alternatively, players can select the Quick Pick option to have Lotto America numbers randomly selected for them. Tickets costs $1 per line, but for an additional $1 players can also select an All Star Bonus option to have any non-jackpot prize multiplied - much like the Powerplay option in Powerball.
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.

Two machines are used in each Mega Millions drawing. The model used for Mega Millions is the Criterion II, manufactured by Smartplay International of Edgewater Park, New Jersey. The balls are moved around by means of counter-rotating arms which randomly mix the balls. Individually, the five white balls, several seconds apart, drop through a hole in the bottom of the mixing drum.

The conditions for Florida joining Powerball included a move of the live drawings from Iowa to Universal Studios in Orlando. The three hosts rotating announcing duties from Universal Studios were Tracy Wiu, Elizabeth Hart and Scott Adams (MUSL headquarters remained in Iowa, where its other draws are held). The wheel that was used to determine the Power Play multiplier was retired when the drawings moved to Florida; a random number generator (RNG) was used until the 2012 format change.

In spite of the huge popularity of this lottery draw game it is still an unknown to many that you can buy Powerball tickets online, whether you are in the US or not. To be clear, this doesn’t even mean that you have to be a citizen of the US either. No citizenship & not based in the US? You can still play powerball online and buy lottery tickets online for a number of different lottery draw games.
