On Oct 4, 2015, the Powerball format changed again; the white-ball pool increased from 59 to 69 while the Powerball pool decreased from 35 to 26. While this improved the chance of winning any prize to 1 in 24, it also lengthened the jackpot odds to 1 in 292,201,338.[19] The 4+1 prize became $50,000; the 10x PowerPlay became available in drawings with a jackpot of under $150 million.[20] Three months later, the format produced a $1.5 billion jackpot, double the previous record, after 20 consecutive rollovers.[19][21]
Players who match five numbers from the first pool win $1 million; those matching four numbers from the first pool and the Gold Mega Ball number win $10,000; those matching four numbers from the first pool win $500; those matching three numbers from the first pool and the Gold Mega Ball win $200; those matching two numbers plus the Gold Mega Ball win $10; those matching one number and the Gold Mega Ball win $4; and those matching only the Gold Mega Ball win $2.
A Powerball jackpot winner may choose to receive their prize in 30 payments over 29 years or a lump-sum payment. The cash value option, in general, is the amount of money required to be in the jackpot prize pool, on the day of the drawing, to fund the estimated jackpot annuity prize. The advertised jackpot annuity and cash value are estimates until ticket sales are final, and for the annuity, until the Multi-State Lottery Association takes bids on the purchase of securities. 
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)."[3][4][5][15] [16]
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.
MUSL and its members accept all investment risk and are contractually obligated and liable to the winner to make all scheduled payments to annuity winners. If a jackpot ticket is not claimed, the funds in the prize pool are returned to members in proportion to the amount they contributed to the prize pool. The members have different rules regulating how unclaimed funds are used.[2]
Powerball® tickets print the white ball numbers in numerical order of a given play. You can match the white ball numbers in any order of a given play to win a prize. The red Powerball number of a given play on your ticket must match the red Powerball drawn. Each play on a ticket is separately determined; players cannot crisscross play lines on a ticket or combine numbers from other tickets. 
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.
