The Powerball jackpot just keeps getting bigger.
There was no winner that matched all six numbers after Monday's drawing, and now the estimated jackpot for Wednesday is $1.2 billion, with a cash value of $596.7 million, Powerball said.
The winning numbers in Monday night's estimated $1 billion jackpot were 19, 13, 39, 59 and 36, and the Powerball was 13. The powerplay number was 3.
While there was no jackpot winner -- though more than 5.4 million tickets totaling $59.5 million in cash prizes won on Halloween -- Powerball said in a press release, including 10 tickets that matched all five white balls for a $1 million prize.
Wednesday's jackpot marks the third time in the game's 30-year history that the main prize has hit the $1 billion milestone.
If there's a winner Wednesday night, the jackpot would be the second-largest jackpot in Powerball history and fourth-largest in U.S. lottery history, Powerball said.
The largest prize in Powerball history, sold in January 2016, was $1.586 billion and was shared by three winners in California, Florida and Tennessee.
