The half-billion jackpot was announced Wednesday morning. If sales go well, that number can go up again to $525 million or even $550 million.
The winning numbers of Tuesday night's drawing were 9, 19, 34, 44, 51 and the Mega number was 24.
Forty-seven tickets had 5 of the 6 winning numbers. Each of those tickets is worth at least $250,000.
Five of those lucky people were from Southern California. Those tickets were sold at a 7-Eleven in Corona, a Unocal 76 station in Fontana, an Arco AM/PM in San Bernardino, Stopper Liquor in Placentia and Surf Liquor in Santa Monica.
Lotto buffs streamed into Surf Liquor Wednesday, hoping some of the store's good luck would rub off on them.
Lottery officials had placed the odds of winning Mega Millions at about 1 in 176 million. The retailer who sells the winning ticket will receive a maximum $1-million bonus.
The next drawing will be held on Friday.
