The Powerball jackpot continues to grow.
With no winner matching all six numbers on Wednesday, the jackpot for Saturday is now an estimated $1.5 billion, which would hold a cash value of $745.9 million, Powerball said.
The winning numbers in Wednesday night's estimated $1.2 billion jackpot were 2, 11, 22, 35 and 60, and the Powerball was 23. The powerplay number was 2.
There was also no jackpot winner Monday -- 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.
