In the United States, lotteries are run by 47 jurisdictions: 44 states plus the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Lotteries are subject to the laws of and operated independently by each jurisdiction, and there is no national lottery organization. However, consortiums of state lotteries jointly organize games spanning larger geographical footprints, which in turn, carry larger jackpots. Two major lottery games, Mega Millions and Powerball, are both offered in nearly all jurisdictions that operate lotteries, and serve as de facto national lotteries.
Note: As indicated in the instructions, for the purposes of eligibility some countries include components and dependent areas overseas. If you are a native of a dependency or overseas territory, please select the appropriate country of eligibility. For example, natives of Macau S.A.R should select Portugal, and natives of Martinique should select France.
On top of the cost of a regular ticket, you can pay extra for the Power Play option which acts as a multiplier of prizes in a similar way to how Mega Millions’ Megaplier does. Taking the Power Play option multiplies winnings earned by matching just one number right through to matching five numbers - turning the $1,000,000 prize into a $2,000,000 prize.
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.
