The Powerball jackpot swelled to $635 million ahead of Saturday’s drawing.
Lottery officials previously estimated the jackpot to reach $620 million.
“When the jackpot reaches this level, we have more players jumping into the game, so we are continuously reviewing ticket sales to provide an up-to-date jackpot estimate,” said May Scheve Reardon, Powerball Product Group Chair and Missouri Lottery Executive Director.
No one has won the Powerball jackpot since June 5.
A single ticket, which can be purchased in 45 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, is $2.
The odds of winning the Powerball jackpot are 1 in 292.2 million, according to lottery officials.
Saturday’s drawing is scheduled for 10:59 p.m. ET.
