The Mega Millions lottery jackpot has risen to $640 million after no one won the top prize in Tuesday’s drawing. The jackpot is the sixth-largest in the history of the nationwide lottery game. The grand prize winner will have the option of taking an annuity that pays the jackpot out over 30 years, or taking the cash payout, a one-time lump sum. The cash payout for $640 million would be $328.3 million. The last time anyone won the Mega Millions jackpot was on Oct. 14. Mega Millions drawings are held on Tuesdays and Fridays. The winning numbers drawn Tuesday are 9-13-36-59-61 and Mega Ball 11.
