The lucky winner of Saturday's drawing could choose between the full jackpot paid in annual installments over 29 years or a one-time cash payment of $316.3 million before taxes, according to Powerball.

But it’s the Saturday, Aug. 23 Powerball jackpot that’s raising eyebrows, currently estimated at $700 million. That total likely will go higher before the drawing because of increased ticket sales. The Classic Lotto jackpot is $6.9 million for Saturday’s drawing.
