Powerball is an American lottery game offered by 44 states, the District of Columbia, Puerto Rico and the US Virgin Islands. It is coordinated by the Multi-State Lottery Association (MUSL), a nonprofit organization formed by an agreement with US lotteries. Powerball's minimum advertised jackpot is $40 million (annuity); Powerball's annuity is paid in 30 graduated installments or winners may choose a lump sum payment instead. One lump sum payment will be less than the total of the 30 annual payments because of the time value of money.
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)."

Lotto America is an American multi-state lottery game that began in 2017. It is operated by the Multi-State Lottery Association (MUSL). It takes its name from the original Lotto America, offered from 1988 to 1992. Lotto America was re-launched by 13 state lotteries on November 12, 2017. Plays are $1 each (or $2 with the All-Star Bonus option; see below.) Lotto America replaced the scandal-tarred Hot Lotto game; each of the 13 members of Lotto America offered Hot Lotto when it ended on October 28, 2017.
The probability and odds can be taken into a mathematical perspective: The probability of winning the jackpot (through October 27, 2017) was 1:(75C5) x (15); that is: 75 ways for the first white ball times 74 ways for the second times 73 for the third times 72 for the fourth times 71 for the last white ball divided by 5 x 4 x 3 x 2 x 1, or 5!, and this number is then multiplied by 15 (15 possible numbers for the "Megaball"). Therefore, (75 x 74 x 73 x 72 x 71)/ (5 x 4 x 3 x 2 x 1) x 15 = 258,890,850, which means any combination of five white balls plus the Megaball has a 1:258,890,850 chance of winning the jackpot. Similarly, the odds for second prize are 1:(75C5) x (15/14) = 1: 18,492,204 chance of winning. The overall probability of winning any prize was 1 in 14.7. If there are no jackpot winners for a specific drawing, the jackpot will keep increasing, however, the odds will still remain the same.
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.
