The odds of matching the five white balls and Mega Ball to win the Mega Millions jackpot are 1 in 302,575,350. A jackpot winner has the option of taking an annuity or cash payment. The annuity is paid out as one immediate payment followed by 29 annual payments, according to the Mega Millions website. Each payment is 5% bigger than the previous one.

“We know that many people will likely receive tickets to Friday’s drawing as holiday gifts, and what a gift that would turn out to be if you ended up with a ticket worth a $1.15 billion jackpot,” Joshua Johnston, lead director for the Mega Millions Consortium, said in a news release before the jackpot rose again to $1.22 billion.
