The Powerball lottery jackpot — the biggest of the year — is swelling after nobody won in Monday night's drawing. The jackpot is now $643 million, with the next drawing set for Wednesday night. Although no one took home the full prize, two Powerball players won $1 million each, according to Powerball.

The odds of winning the Powerball jackpot are one in 292.2 million. The odds of matching all five white balls and winning the $1 million prize are 1 in 11,688,053. The overall odds of winning a prize are 1 in 24.87.

More than 755,000 other Powerball tickets sold in the United States also won prizes ranging from $4 to $1 million, the lottery said.
