Meanwhile, it's Powerball's turn to take the big-jackpot spotlight.
Two winning lottery tickets worth millions of dollars were sold in the Central Florida area, meaning locals who chose to test their lottery luck should check their numbers. The prizes must be claimed at the Lottery's headquarters in Lansing.
Note: Michigan's $1 million winners should contact the Michigan Lottery Public Relations Division at 517-373-1237 to schedule an appointment to collect their big prize.
Wednesday's Powerball lottery prize stands at $620 million, making it the fifth-largest jackpot in US history, after no one got all six numbers in Saturday's drawing. They were bought in 17 states and the District of Columbia.
South Carolina's lottery director says they hope to reveal the identify of the store that sold the winning ticket by mid-day Wednesday. Otherwise, the jackpot is doled out over 29 years.
This story has been corrected to show that the Mega Millions lottery won Tuesday night was the second-largest based on actual sales, not the world's largest-ever lottery grand prize, based on final details provided by the lottery.
The last time that happened was July 24, when 11 co-workers from California won a $543 million prize.
