Less than 50% of the possible number combinations for Wednesday night's drawing have been sold, California Lottery officials said.
"We're getting into this routine now where this is becoming normal," spokesman Alex Traverso said, "which is great for us because when you look at sales, they're steadily climbing."
Even though sales are no longer "exploding" as they were when the wave of nine-digit jackpots began, he said that collectively, the spikes in sales add up.
The bigger jackpots are drawing more players and excitement to the California Lottery after years of decline. The turnaround is a result of changes made to the lottery in 2010, when revenue was falling.
About a month after the state joined the game, a Powerball jackpot climbed to about $600 million, setting a record for the game. Officials say that with Powerball's $2 tickets, jackpots in that game can rise faster with fewer tickets sold than in a game like Mega Millions, which costs $1 per play.
