Annuity option in play as Mega Millions jackpot grows to $640M

The Mega Millions top prize grew again to an estimated $640 million after there was no winner of the lottery's latest giant jackpot.

The numbers drawn late Friday night were: 10, 24, 48, 51, 66 and gold Mega Ball 15.

The estimated $640 million jackpot in the next drawing would only be distributed to a winner who chooses an annuity paid over 29 years. Nearly all grand prize winners opt to take a cash payout, which for Tuesday night's drawing is an estimated $328 million.

The jackpot is the seventh largest in the game's history, Mega Millions said in a statement.

Four tickets matched all five white balls to garner the second prize level in the drawing. A ticket sold in South Carolina included an optional multiplier, making it worth $2 million. Two tickets in California and one in North Carolina also were second-tier winners, Mega Millions said.

Despite the game's long odds of 1 in 302.6 million, players continue to purchase tickets as the size of the grand prize grows.

The last time a Mega Millions player hit the top prize was April 18.

Mega Millions is played in 45 states as well as in Washington, D.C., and the U.S. Virgin Islands.
