The Mega Millions jackpot is now over $1 billion. The new estimated jackpot will be the nation's fourth-largest lottery prize.

DES MOINES, Iowa — A giant Mega Millions lottery jackpot ballooned to $1.02 billion after no one matched all six numbers Tuesday night and won the top prize.

The jackpot has grown so large because no one has matched the game's six selected numbers since April 15. That's 29 consecutive drawings without a big winner.

Mega Millions is played in 45 states as well as Washington, D.C., and the U.S. Virgin Islands. The game is coordinated by state lotteries.

Tuesday night's winning numbers were 7, 29, 60, 63, 66 and the Mega Ball 15. The next drawing will be Friday at 11 p.m. ET.

If there is a winning ticket Friday, the $1.02 billion jackpot will be the third largest Mega Millions jackpot prize in the game's 20-year history, according to the Mega Millions.
