DES MOINES, Iowa – The Powerball jackpot has reached a new high of $365 million – making it the largest jackpot in U.S. lottery history.

With no winner Wednesday, the multistate Powerball jackpot jumped for Saturday’s drawing. The jackpot is expected to spark a frenzy of ticket sales.

“It’s been crazy already,” Jasmina Goretic, a clerk at a Dahl’s Food Mart in Des Moines, said Thursday.

The Powerball jackpot tops the previous lottery record, which was $363 million for the Big Game – the forerunner of Mega Millions. It was won by two ticket holders in Illinois and Michigan in 2000.

Powerball’s previous record of $340 million was won by an Oregon family in October.

The chances of winning the jackpot are 1 in 146.1 million. The tickets cost $1 and players try to match six numbers.

The game grew out of the Lotto America game, which started in 1987 in seven states. It evolved into Powerball in 1992 and, since then, more states have been added – 28, including Idaho, plus the District of Columbia and the U.S. Virgin Islands.
