One of the largest Mega Millions jackpots ever is on the line Tuesday with an estimated grand prize of $530 million.

Only seven of the previous Mega Millions sweepstakes have yielded a bigger jackpot, with the largest coming in October 2018 with a $1.5 billion prize.

Tuesday’s Mega Millions drawing will take place 11 p.m. EDT. The winner’s numbers must correctly match up with the five white balls and the gold Mega ball in order to hit the jackpot.

The odds of winning the jackpot: 1 in 302,575,350, according to the Mega Millions website.

Friday’s drawing saw one person in California match each of the five white balls for $1 million, but not the gold ball for the grand prize.

Only two Mega Millions sweepstakes have ever exceeded a $1 billion jackpot, with the second instance occurring last year. Seven others have reached a grand prize above $500 million.

Tuesday’s drawing includes a cash option for the jackpot of $304.7 million.
