Powerball is Now Up to $620 Million

After nearly four months without a big winner, the Powerball jackpot for tomorrow night has climbed to an estimated $620 million-- the 10th largest US lottery prize.

There have been 39 drawings in a row without a Powerball grand prize winner. The last time someone hit the jackpot was June 5th.

Although the jackpot is billed as $620 million, that's the estimate for the annuity option paid over 30 years. Winners nearly always opt for the cash option, which for Saturday's drawing will be an estimated $446 million.
