This weekend's Powerball jackpot will be worth at least $300 million, so the $2 tickets are likely to sell quickly.
Saturday's jackpot is still well below the record Powerball jackpot of $590.5 million that an 84-year-old Florida widow won in May.
But it's big enough to attract casual players who only buy tickets when they think the payoff is big enough to be life-changing.
The odds of matching all six numbers -- five white balls plus the Powerball -- are 1 in 175.2 million.
Lottery officials expect plenty of tickets will be sold in the 43 states that offer Powerball. Tickets are also sold in Washington D.C. and the U.S. Virgin Islands.
