You can increase your non-jackpot winnings by purchasing the PowerPlay option as well; you can do so by marking "YES" next to Power Play option. You can also play the same numbers you selected again any number of times by marking the multi-draw option. Then you take your play slip to the retailer and have it processed.

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.

No one hit the jackpot in the Monday, Aug. 18 drawing, so the grand prize will increase to an estimated $643 million.
