ORLANDO, Fla. (AP) -- The Powerball jackpot is expected to grow to an estimated $57 million for Saturday since no one matched all six of the numbers in the midweek drawing.

Last night's winning numbers were 18-23-36-47-and-59. The Powerball was 4 and the multiplier was also 4.

Players matching all five numbers and the Powerball would have won or shared the $45.5 million jackpot.

Two Power Play tickets sold in North Carolina and Pennsylvania matched the first five numbers only to win $1 million.

Colorado's top prize was $400 for 31 Power Play tickets that matched other number combinations.

Powerball was created in 1992 and launched in Colorado in 2001.

It's now played in 30 states, the District of Columbia and the U.S. Virgin Islands.
