The Powerball jackpot is now an estimated $1 billion for Saturday night's drawing. There was no grand prize winner for Wednesday's roughly $850 million jackpot, and Powerball initially said the increased jackpot was approximately $950 million. Game leaders reviewed national ticket sales and increased the jackpot, Powerball said Friday.

Monday’s drawing — the 37th since the jackpot was last won — could be anyone’s game, with $750 million up for grabs in the Powerball jackpot. It will be the 10th largest in the game’s history, after no ticket matched all six numbers in Saturday’s draw.
