Sales grow as Powerball jackpot reaches an astounding $900 million

MILWAUKEE -- With Powerball sales breaking records, the jackpot has jumped once again -- to $900 million.

But if no one matches all the numbers Saturday, the next drawing is expected to soar to $1.3 billion.

Officials with the Multi-State Lottery Association, which runs the Powerball game expect about 65 percent of the possible number combinations to have been bought for Saturday night's drawing.

That percentage could rise if the jackpot estimate is increased before the drawing. But even lottery officials say they don't know what to expect.

Since Nov. 4, the Powerball jackpot has grown from its $40 million starting point as no one has won the jackpot.
