Powerball jackpot reaches $425 million

At $425 million, Wednesday's Powerball jackpot could be one of the largest prizes in the game's history, and if the pot goes unclaimed yet again, the prize will grow even larger.

"Good Morning America" co-anchor Robin Roberts suggested Monday that in recent months pots have been growing so quickly that people won't even consider playing until the prizes reach nine digits.

"It's interesting, because people are like, '$50 million, I'm not going to play for $50 million," Roberts said on "Live! with Kelly and Michael." "'While, oh, $300, $400, now I'm in.'"

Party to blame -- or thank -- for the increasingly rapid growth of the prizes are lottery officials, who in Poweball's case, doubled ticket prices from $1 to $2 at the beginning of last year also doubling the amount going into the jackpot.

Tonight's jackpot comes only three months after Gloria C. Mackenzie, 84, of Zephyrhills, Fla. took home Powerball's largest payout ever -- a one-time payment of $370 million, before taxes.

The odds of an exact match of all six numbers are 1 in 175.2 million.
