The winning numbers for Saturday's drawing were 21, 24, 36, 42, and 45, with the Powerball 15.
The revised estimated jackpot wasn't available immediately after Saturday's numbers were drawn, but it was expected to fall well below the record $590.5 million jackpot that was won in May by an 84-year-old Florida widow.
Saturday's pot was big enough though to attract casual players who only buy tickets when they think the payoff is big and potentially life-changing.
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.
