A record Mega Millions drawing will take place Tuesday with a massive jackpot of nearly half a billion dollars ready to be claimed.
The jackpot has grown to at least $493,000,000, the fifth largest in Mega Millions' 16-year history. The odds of winning is less than 1 in 302,000,000.
If people buy enough tickets, the prize could surge past the half billion mark.
The prize is the largest total since March, when $533 million was awarded to a person in New Jersey.
The grand prize was last won May 4. Since then, the jackpot has rolled over 22 times.
