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.
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: 
The minimum jackpot prize is a $15 million annuity disbursed in 30 payments over 29 years which is something many people would elect to do.The 30 annuity payments are not equal but based on an increasing rate schedule. For example, the first annual gross annuity payment on the base $15 million jackpot would be approximately $267,000 while the final payment would be approximately $834,000.
On January 13th, 2016 the American multi-state lottery Powerball set the world-record for the biggest jackpot of all time at USD$1.6 billion when it was won by John and Lisa Robinson of Tennessee, Maureen Smith and David Kaltschmidt of Florida and Marvin and Mae Acosta of California. It was the first time in history a prize had topped the billion dollar mark!
Under the current version's regulations (which began October 28, 2017 with the first drawing October 31) for Mega Millions, the minimum Mega Millions advertised jackpot is $40 million, paid in 30 graduated yearly installments, increasing 5 percent each year (unless the cash option is chosen; see below for differences by lotteries on cash/annuity choice regulations.) The jackpot increases when there is no top-prize winner[1] (see below for information on how the Mega Millions jackpot is funded.) As of December 13, 2017, there has yet to be a jackpot winner under the current Mega Millions format, including wagers for the newly created Just the Jackpot option.
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.
