Some retailers that sit on state lines often offer both state lotteries with state boundaries clearly marked, since such sales still have to occur in the physical state it is offered. One retailer located along U.S. Route 62that is largely in Sharon, Pennsylvania but has a small portion lying inMasury, Ohio sells both the Ohio Lottery and the Pennsylvania Lotteryat one location. The first modern US joint-state lottery game was formed in 1985 inMaine, New Hampshire, and Vermont. In 1988, the Multi-State Lottery Association (MUSL) was formed with Iowa, Kansas, Missouri, Oregon,Rhode Island, West Virginia, and the District of Columbia as its charter members; it is best known for Powerball, which was designed to create large jackpots. Another joint lottery, The Big Game (now called Mega Millions), was formed in 1996 by six other lotteries as its charter members.
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)." 
*a tip to know whether the website you are looking at actually buys lottery tickets online or follows the insurance model is to check the wording that they use. If you see the words “Play” then you can be confident it is a company that has agents and buys your tickets physically, if you see the words “Bet” you can be sure it is following the insurance model and you are placing a bet on the outcome of a lottery.
Draws are held on Wednesdays and Saturdays at 10.59 p.m. (EST) and there are five winning numbers drawn from a pool of 69 balls, as well as one extra ball called the Powerball. If you're lucky enough to match five numbers and the Powerball, then you'll hit the jackpot, just like the many winners over the years. Be sure to visit this page after the latest draw for the most recent Powerball lottery results, to find out if you're one of those lucky people.
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.
