With Powerball sales breaking previous records, the odds are growing that someone will win Saturday night’s $800 million jackpot — but if no one matches all the numbers, the next drawing is expected to soar past $1 billion.

For this weekend’s record drawing, about 65 percent of the possible number combinations will have been bought, officials with the Multi-State Lottery Association, which runs the Powerball game, said Friday. That percentage could rise if the jackpot estimate is increased — but even lottery officials say they don’t know what to expect.

“You can throw out the logic. You can throw out the statistics,” said Gary Grief, executive director of the Texas Lottery. “We’ve never seen jackpots like this. It’s a new experience for all of us.”
