The only way to be sure that what you are buying is “official” is to purchase your tickets from a company that has agents that will purchase in the real world the Powerball tickets online that you have selected. If you are a more trustworthy person and don’t need a scanned copy of your Powerball tickets online then by all means go for an online lottery ticket provider that follows the insurance model.

Reflecting common practice among American lotteries, the jackpot is advertised as a nominal value of annual installments. A cash value option (the usual choice), when chosen by a jackpot winner, pays the approximate present value of the installments. Mega Millions' previous format began on October 19, 2013; its first drawing was three days later. The current version of Mega Millions uses a 5/70 (for the white balls) plus 1/25 (for the "Mega Ball") double matrix to select its winning numbers.
The US Powerball lottery features nine prize divisions; players need five winning numbers from a drum of 1-69 and the Powerball to win the jackpot prize. The Powerball is an additional number, chosen from a separate drum of 1-26. Matching the Powerball will also give you access to the 3rd, 5th, 7th, 8th, and 9th prize categories, which means that even if you match only the Powerball number, you still get a prize. Even without a Powerball match, correctly guessing five main numbers would net you a $1 million prize, or $2 million if you use the Power Play! The Power Play is offered by the US Powerball for an additional cost and multiplies the seven bottom prize divisions by 2 to 10 times! Check more lottery results online with theLotter!
