The Powerball, which is the 8th largest jackpot, is up to $640 million. The odds of winning are one in 292.2 million.
The Powerball Jackpot numbers were 14, 20, 39, 65, 67 from Saturday's drawing. The Powerball number is 2.
Another on of the largest jackpots in U.S. history will grow even larger since there was no winner for Friday's drawing of the Mega Millions' $750 million top prize.
Those numbers were 3, 11, 12, 38, 43, with a Mega Ball of 15 and would have marked the fifth-largest jackpot ever drawn.
There were many smaller winners Friday.

It's been nearly two years since a lottery jackpot has grown so large. No one has won either game's top prize in months.
The listed jackpot amounts refer to winners who opt for an annuity, paid over 30 years. Winners nearly always choose cash prizes, which for Powerball would be $478.7 million. The estimated cash prize for the next Mega Millions jackpot is $628.2 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.
