(ABCNEWS.GO) — The Powerball jackpot has swelled to $425 million, the largest in the lottery’s history, after no tickets matched the winning numbers in a drawing Saturday night.

The Powerball numbers for Saturday were 22-32-37-44-50, and the Powerball was 34.

Iowa Lottery spokeswoman Mary Neubauer said the jackpot could get even bigger before Wednesday, because sales tend to increase in the run-up to a big drawing.
