The Mega Millions prize was already giant, but now it's absolutely massive.
Lottery officials have raised the estimated jackpot for Tuesday night's drawing to $667 million, making it the third-largest grand prize in U.S. history. The increase from $654 million reflects a surge in ticket sales.
The record lottery jackpot remains a $1.6 billion Powerball prize won in January 2016.
Although the Mega Millions prize has grown larger, the odds of winning remain the same at 1 in 302.5 million.
The $667-million jackpot refers to the annuity option, paid out over 29 years. The cash option, which is favored by nearly all winners, is $380 million.
The last time anyone won the jackpot was July 24, when a group from California claimed a $543-million prize.
Mega Millions is played in 44 states — including California — as well as Washington, D.C., and the U.S. Virgin Islands.
California has had winners in three of the top 10 largest jackpots. Here is a look at the 10 largest U.S. jackpots that have been won and the states where the winning tickets were sold:
