The coveted Powerball jackpot is still up for grabs, which means there's still a chance to take home the over half-a-billion-dollar grand prize. The current jackpot is estimated to be worth $643 million,

The Powerball jackpot has grown to $643 million -- with a cash payout of $290.6 million -- after no one won Monday night's drawing. A total that was already the highest of the year has now crept higher. The next drawing will take place Wednesday night.

No one hit the jackpot in the Monday, Aug. 18 drawing, so the grand prize will increase to an estimated $643 million.
