The prizes have grown so massive because it has been months since anyone has matched all six numbers and won either jackpot. The odds of winning it all are incredibly small, at one in 292.2 million for Powerball and one in 302.5 million for Mega Millions.
The jackpots listed by the lotteries are for winners who opt to be paid through an annuity over 30 years. Nearly all winners take the cash option, which for Powerball would be an estimated $411.4 million and for Mega Millions would be $550.6 million.
Mega Millions and Powerball are both played in 45 states as well as Washington, D.C., and the U.S. Virgin Islands. Powerball also is offered in Puerto Rico.
