Wednesday's estimated Powerball jackpot has grown to $425 million because of strong sales nationally.

No one hit the Powerball jackpot on Saturday, so the money rolled over. The estimated jackpot was $400 million before Tuesday's announcement.

While hefty, the prize for Wednesday's drawing is still well below the record $590.5 million jackpot won in May by an 84-year-old Florida woman.

The winning numbers Saturday were 21, 24, 36, 42 and 45; the Powerball was 15.

The odds of matching all six numbers are 1 in 175.2 million.

Powerball is played in 43 states, Washington, D.C., and the U.S. Virgin Islands.
