The previous record jackpot in the Mega Millions game was $390 million in 2007, split by two winners in New Jersey and Georgia.
In Tuesday night's game, 47 players came very close, matching 5 of the 6 winning numbers. Each of those tickets is worth at least $250,000.
Mega Millions is played in more than 40 states, the District of Columbia and the U.S. Virgin Islands. Lottery officials had placed the odds of winning Mega Millions at 1 in 176 million.
So what if you do beat those odds?
Experts say you'll want a team of financial advisors, including a tax expert. Then, keep a low profile or risk getting inundated by friends and relatives you didn't know you had. Also, don't go on a spending spree - most winners spend all their money within five years.
The retailer who sells the winning ticket will receive a maximum $1 million bonus.
